Weird-ass select button issue with a 1 slot / 4 slot, and Stereo on a 4 slot in AWSD

[kernow]

uhm

In preperation for my 4 slot coming, last week I wired up my select button and it worked fine, I wired it up to a spare button (HK on the kick harness) and it worked lovely, as it was a one slot I chucked it into home mode (unibios) and tried pausing it, yep worked fine, did a quick button test in the test menu, yep nothing wrong.

so today I get the four slot through and its completely minging but in good overall condition so I give it a thorough clean so now its minty, I got a few issues but I think its mainly dirty carts or slots, so I got my contact cleaner and sprayed it a few times, and I'll clean my carts in future, annnyway.

uh, select no longer works on the four slot OR the one slot. , I got a mate around to test continuity from the jamma edge and its fine, the wire isn't broken at all, so I don't know wtf is wrong, the ground is fine for that button too as it works fine connected to other ones. I've even tried joining the ground wire to the select button wire and ... nothing, you'd expect the 0 to turn to a 1 in the test menu, but nope. wtf

also, I realised I was getting screwy sound on the four slot, because it was running in mono, I plugged in the little four pin connector that Mr Megalo told me about and it seemed to even the sound out so it sounded 'correct'

only thing is when I change the switch on the AWSD control panel from mono to stereo, all sound is cut, it only works on mono, when I do a sound test, in the MVS test menu I test the right channel and it comes out of both speakers, the left is nothing, so I can only assume its running in mono still , even with the little four pin connector connected to the side of the board.

the switch is still in mono too so its obviously.. still running in mono.

I am puzzled as to why my select button now no longer works even with the 1 slot, whereas last week it was completely fine, so wtf is going on there?

apologies for the long post. any help would be awesome :ohmy:

[Mr-Megalo]

I didn't know you could use the select button with 1 slots, does it just act as pause button ?

i'm guessing its a grounding issue

[kernow]

yeah, you can use it with a one slot (in the test screen its still there, which is useless) and in AES mode using a unibios, it does whatever the select button would do on a home system stick (i.e pause in most games)

grounding issue, hmm, surely if I tried another ground it'd do something, I dunno.

I can't see how it was working last week and I've changed literally bugger all, and now its not working at all.

[gundaRn]

Only works as pause if you have Unibios set to console rather than MVS.

Dunno about the problem though, if it did work and now doesn't, could be grounding.
What BIOS are you using now?

[Mr-Megalo]

IIRC not all the grounds on the Egret II/ Egret III/AWSD are "common" with each other, its part of the reason why things like the Super/MGCD boards NEED an adaptor for them to work

[kernow]

Only works as pause if you have Unibios set to console rather than MVS.

Dunno about the problem though, if it did work and now doesn't, could be grounding.
What BIOS are you using now?

unibios 1.0 , it was a 1.3 but I've had a 4slot euro bios in there too

(is there any difference between a 1slot euro bios and a 4 slot euro bios do you think ? it works fine)

gonna quickly put a different bios in just in case. but hmm

[gundaRn]

Unfortunately, I've done a ton of arsing around with select buttons on my six slot and everytime I rewired it, it was fine.

Have you wired up "select up" or "select down"?
I always did both, I have a rocker switch on my harness to do it now, and on my Big Pink it's just wired up to the "flipper" buttons on an X-Arcade stick.

[kernow]

uhm, LOL

it was grouding on the CPS2 as the kick harness was still connected to the CPS2 motherboard. (HK/select on both 1p/2p)

I just need to remember to disconnect the CPS2 kick harness whenever I connect up the four slot.

well thats that problem solved, I can solder up those two sides as they are simply twisted together at the moment.

so , about the mono/stereo issue on the four slot, I guess thats next.

(select up on 1P HK, select down on 2P HK)

[kernow]

oh fucksake, my D button ground was joined to the C button ground, and that fell out as it wasn't soldered, so I try to do that properly and now both selects aren't working again

I am such a fucking noob, I might just wait until tomorrow when my mate is back, jesus F christ. :laugh:

[gundaRn]

At least you always learn from your mistakes.

Not that I ever make any... :happy:

[Mr-Megalo]

the only mistake I ever made was not travelling back in time and stopping my parents from meeting

[kernow]

Mark sounds like he wants to be the next Doctor, haha

bizarre, whereas before on the one slot select was working, now it does bugger all on both sides, I plug the four slot in, and it works perfectly on both sides *explode in frustration*, oh well, I guess its working how I wanted on the multi-slot I guess. Although on CPS2, I have no 1player HP, whereas its fine on the other side, lol. Man I'm really not very good with wires and shit.

oh, is this a power issue do you think? I've had similar on my woodie when playing metal slug, I don't see how its only on MS1 and MSX works fine though (see the black bars down each side?) I'd imagine the four slot draws more than the 1 slot and would probably need the 5/12 on the power supply bumping up a little. :unsure:

[Mr-Megalo]

it could be a PSU / amperage related issue as the AWSD wasn't really designed with multilot MVS in mind, have you tried the cart on the 1 slot and if so does it display the same black bars on that ?

going from memory, this is with the 2nd AWSD you got when I replaced your tube which we initially had problems with isn't it ?

and no I don't want to be the next Doctor, unless you mean Dr Emmet Brown - then yea i'd be up for that (would give me chance to drink a pint or two of plutonium :laugh: )

[kernow]

Yeah, its fine in the 1 slot with MS1, I might try tweaking the psu a little

and yes this is the one (pangs) that the psu was fooked on when it arrived, well not fooked, but in a coma so to speak.

I don't understand how more demanding games even the giga shock ones are fine though, it seems to only be metal slug. I think its gotta be a power issue but really you'd expect artifacts or weirdness on other games too, but nothing.

:unsure:

I'll play about with it more tomorrow, my extension harness hasn't arrived yet, should be later this week, so I'll be able to actually fit it in the cab, as for stereo sound, christ knows. even with that little dongle connected on the side its still mono , I'm pretty sure

[Mr-Megalo]

do me some pics for when I get home sometime tomorrow (i'm up in 4 hours with an early setoff and unknown finish) for me to have a gander over - I want to see which connector you have connected up on the MVS's stereo connector and whatnot, when the cab is set to stereo via the switch, volume controls are split left and right and thats why they have 2 seperate volume knobs one for left channel, one for the right the one you use for mono is no longer used. TBH Neo Geo has never been my strongest point as I was more interested in playing the games than learning anything about it really

[Mr-Megalo]

also, and yes I know the screen is tated, but try the MSlug setup that displays black bars on AWSD No2, on AWSD No1 and see if that displays the same issue

process of elimination kinda thing

[Mr-Megalo]

P.S - I am charging you an hourly rate for this advice :laugh: kern your going to put my kids through college :smile:

[kernow]

hmm, thats a clever idea mark, I'll try that in a sec.

(marks a clever geez)

edit: BWAHAHA, at least I keep the tech section busy I suppose.

I'll get you a bottle of JD or sommat, .. cough one day when I'm a little richer.

I appreciate any help I really do , you know that my old mucker. :wub:

[Mr-Megalo]

i'm only kiddin with ya - no need for owt mate, unless you know of an Elle McPherson look-a-likey and a Jenifer Love Hewitt look-a-likey who can distract me for a bit :biggrin:

[kernow]

Yep, does it on the tate cab too, awesome :rolleyes:

But I guess they are pretty much identical on the 5/12 voltages because a couple weeks ago we made sure they were pretty much the same, ahem.

I'm hoping thats it really, fuck I'm anal

why does it only have to be metal slug that does it, makes no sense if you ask me.

[Mr-Megalo]

i'm thinking amperage, especially if it doesn't display the issue with a 1 slot.

it might be a boot :wacko: :laugh: j/k

i'm stumped mate, as I said MVS has never been and never will be my forte (and I think the Metal Slug games are extremely over-rated :blush: )

[kernow]

haha, yeah the later metal slugs (and most later neo games), can feck right off

by amperage I guess you mean changing the psu voltage will affect it? (if you can't tell already, I know feck all about volts and current etc, probably why I got fired from my last job where I had to help teach electronics n stuff)

I take it its drawing a higher current (amps) and that requires a higher voltage to power it, ahem

stab me in the face if I'm talking bollocks, which I probably am. Just prodding in the dark, like I do every friday night after a few beers. cough

[kernow]

mmh, been doing a bit of reading old threads on killercabs, and it seems I might need some sort of MVS->JAMMA adaptor board (seen them for sale before) sigh, more money

I tried hooking up the supplied stereo connector in the cab, and managed to get the LEFT speaker test coming out of the LEFT speaker, but fook all out of the right speaker test. blargh

guess I could just run it in mono but that sucks a bit, I don't think the stereo connector from the cab actually fits to the header on the adaptor either.

honestly, fuck cabs in the ass sometimes, I might just give up gaming all together, lol :laugh:

[Mr-Megalo]

I had Pete (thechop) 4 slot running in stereo no problems on his AWSD, I think on yours aswell (I was going to mod the 2 sync lines so you could join them, only to find that little white connector at the front so didn't need to)

[Mayhem]

mmh, been doing a bit of reading old threads on killercabs, and it seems I might need some sort of MVS->JAMMA adaptor board (seen them for sale before) sigh, more money
You're running a multi-slot MVS board in a straight-up JAMMA cabinet without any kind of adapter? That's definitely a bad idea...

As for the MS1 problem, have you tried running the cart in different slots? These motherboards can be finicky or so I understand.

[kernow]

ok, I'll stop running the four slot in there until I get an adaptor, I guess. can anyone point me out as to which is the best one? does 'thechop' use one? hmm

Yeah, MS1 does it in every slot, you'd think a more demanding game like MSX would do the same, but nope. meh.

I'll ask over at killercabs too because I've noticed quite a few people harping on about those MVS->JAMMA adapters, thankies ;)

[kernow]

Well at least I got select up/down working with both 1 slot and 4 slot.

I replaced the unibios 1.0 in the 1 slot with the 4 slots original euro bios and both started working, the 4 slot has a unibios 1.3 in, so maybe theres some bug that got fixed between 1.0 and 1.3, or I'm being stupid and missing something else.

I bridged the ground for my D button off C on both sides, and this works fine on MVS (ABCD+select on both sides) but on CPS2, only Hard Punch (C) on the 1p side isn't working, whereas on 2p side, it works fine, I think I bridged the ground off something different for D on the 2p side actually.

But you'd think putting the 1p C button wire on a different button with a different ground would make it come back to life, but nope. lol .. I suck \o/

Going to hold off putting the four slot in again because of what you've just told me about, don't want to blow or damage anything, so I'll investigate those adapter boards first.

[gundaRn]

I've never used an MVS to JAMMA adaptor and everything has always been fine for me.

[kernow]

*passes out*

[kernow]

Well I've got C(HP) working on the 1p side. so everythings sorted related to buttons and selects and grounding etc (christ)

stay tuned for the chronicles of kern-noob and his cluelessness, and how he sorts out stereo on this damn 4 slot in the near future \o/ :laugh:

MKL on KC said about a MVS stereo out -> JST 4 pin connector, I have a pic of it here, so thats probably needed too, he never got feedback from the buyer as to wether it actually did the job or not though, hmmmehh.

http://i7.photobucket.com/albums/y278/parple/jstmolexue7.jpg

voila. (this plugs into the MVS->jamma adapter card header)

[gundaRn]

The 4 pin plug you are talking about there, I just cut them off old PC power supplies and wire them up myself (they are the ones used to power the floppy drive).

[kernow]

excellent! I might do that too

I wonder if it'll fit the other (MVS adaptor) side also? hmm


edit: doh! that would be the mvs adaptor side as the other side is just pins, what about that side? I dunno where to get those pin things from, I guess I could rape those from an old floppy drive too huh? :p

[Mr-Megalo]

wish I could remember what the extra header cables were labelled, I can't remember if it was the "P" connector I used or not

[thechop]

[QUOTE=kernow;12754]ok, I'll stop running the four slot in there until I get an adaptor, I guess. can anyone point me out as to which is the best one? does 'thechop' use one? hmm

I've only ever used a 1-slot in the AWSD 'cause they're standard JAMMA, my 6-slot i've put back the Lordsvale which is MVS standard, so i've never used an adaptor in the AWSD but i use an MVS>JAMMA in the Lordsvale if i'm playing CPS2's in it but i'd recommend a JAMMA>MVS adaptor to play a multislot in your AWSD not too sure why but it's supposed to be a bad thing to do Multislot in a standard Jamma with no adaptor.

[thechop]

Oh, got mine from here-
http://www.jammaboards.com/store/neogeo-mvs-to-jamma-adapter/prod_198.html

Also they're Binkerball on eBay, think i had mine off the bay:sick:

[kernow]

http://i7.photobucket.com/albums/y278/parple/molexes1.jpg
http://i7.photobucket.com/albums/y278/parple/molexes.jpg

labelled the other way round on an E2 apparently.

I've now cut off the floppy power cable from a PC PSU, so I have that part, but not the pins on the other side, hehe.

[Mr-Megalo]

the "P" connector, is used for the Atomiswave stereo connector on the awave motherboard, thats the detachable one on the AWSD isn't it ?

[kernow]

Not sure if its detachable, I presume you mean the other end, right. (haha of course)

looks like all I need is one of these

http://i7.photobucket.com/albums/y278/parple/A-10.jpg

and one of these (to connect to the JST connector)

http://img144.imageshack.us/img144/9051/jstmolexue7.jpg

and I should be (finally) trucking, then I can look into why slug has those funky borders, probably a voltage issue, gotta be really.

[thechop]

Weird one that, the funky borders:unsure: i find putting the carts in order of size(megs) usually does away with any strange behaviour.The same 6 games which will not all work together suddenly will if you get the order right, takes a bit of jiggery-pokery tho':sad:

[kernow]

Yeah, I've heard about the 4/6 slots being fussy with cart/megabit arrangments in the past, such as giga-shock games not knocking out others and what what.

trying to find a thing with four pins on so i can solder these wires to it like in the diagram, apart from desoldering one from an old floppy drive I'm stumped. I guess I could just get MKL to make one as he made the one above.

[kernow]

MKL is going to make me up an adaptor as he has the proper parts, so thats cool. I doubt it'll cost that much, its only a few wires really. \\o

Waiting for that yaton (yes him) to email back relating to the adaptor, and it looks like I'm almost set. phew.

[Mr-Megalo]

MKL is just an awesome dude isn't he

[vib_ribbon]

MKL is just an awesome dude isn't he

amen.

[kernow]

Yeah, the guy is a star, has helped in the past with some other stuff too, knows his shit, much like you guys :p

[kernow]

JAMMA extension arrived and ... its not a straight-through which can take MVS, its just literally a JAMMA extension (duh) and I have no select or D button when using it.

fucking awesome :ohmy:

[guddler]

Ok, back to plan A then!! - I'll pick up a new battery next week, send you yours back and ensure theres a jamma adapter in there for you to make up your own MVS adapter :smile: You know what they say - if you want to do something right, do it yourself :laugh:

[kernow]

To be honest I think my mate has a fingerboard and he's going to make up an extension today for me, so I'll probably not need it next week.

I'll just use this extension in another cab I guess. hmm, or something.

Someone did say on KC about swapping the -5v pin over as its not used in an AWSD anyway, but I'd still need to swap another pin, a ground maybe? I dunno really.

[Mr-Megalo]

you can take the wire off of -5v and add that to the D yes, AWSD as defautl has no -5v unless you add something called a "negatron"

[kernow]

I've chucked it in the vert AWSD now, its good to have the harness a little longer in that one I guess, but I didn't really need it at all. - bah!

[Mr-Megalo]

I believe they call that sods law :laugh:

[Mr-Megalo]

Serve the public trust
protect the innocent

:rorocock:

[kernow]

yes, pretty much, always the same with me LoL :laugh:

[gundaRn]

JAMMA extension arrived and ... its not a straight-through which can take MVS, its just literally a JAMMA extension (duh) and I have no select or D button when using it.Hence my post earlier about making mine myself.
Also, one thing I found with an extension on my six slot is that the longer it was, the more it messed with the voltage on the connector.
Four Slot might be fine.

Thats a fair point actually.... bugger

hmm, what can go wrong, (for kern), will go wrong

(all my jamma stuff including cabs is going in the bin outside soon, I swear) :laugh::wink:

[Mr-Megalo]

/puts on Binman outfit

[kernow]

:laugh:

[kernow]

lol, jesus, I've just realised that the adaptor card I'm getting:

http://i7.photobucket.com/albums/y278/parple/A-10.jpg

As you can plainly see, select (and maybe D?) isn't wired up even on this bloody convertor :laugh: So my jamma extension harness I bought for £20 actually will be fine, and I'll just wire the D/select off the adaptor card instead.

sigh :)

I might go and put the board in, I'm that bored.

oh .. yesterday was fun, I went to turn my horizontal cab on, and it wouldn't come on, wtf, I switched it on from the stepdown and mains block (2 switches) and still, it was dead as a doornail.

I panicked and thought , must be the bloody wei-ya PSU as its gone and kicked the bucket or sommat, so I started diagnosing and looking for bad connections and faults, took the psu case off to see if the fuse had gone.

then about 8minutes later. I remembered the cab had a switch on it too, flicked that, oh look, the whole thing has come on


god I'm excellent, .. at being a retard. \o/

Then I just put the casing back on and started playing LB1 and shiz.

[Mr-Megalo]

thats as bad as me sometimes, I call them "schoolboy errors"
we've all done them, whether it be not realising about a power switch or plugging a board in the wrong way round

[gundaRn]

we've all done themBut yours is still quite spectacular.

:pacers:

[kernow]

I'm tempted to just plug it in directly again and see if the MKL harness is the same as the 4 slot stereo output, then I dont need the adaptor and dont need to rewire D or SELECT either.

I know mayhem said you're not sposed to do it, but I know loads of people that have and I've never ever heard of a blown board. hmm :huh:

edit, ah I'm a dick, I'd still have no D or SELECT due to this extension harness, no big deal. I'll wait for the adaptor card, its been stuck in UK customs for the last two days (eep!) :)

[kernow]

Bizzare. I guess it could be a grounding issue again but I doubt it.

I got the card / adaptor today, when I plug it in and MKL's harness, I get stereo woo! :wub:.. sounds great too.

I was getting around to wiring up select and D from the card, and I did a quick controller test, I've noticed that when I press the A button on the 2p side, select down is pressed too. wtf? if I press A on 1p, only A is pressed.

looking on the actual tracks on the card, I can sorta see that P2-A is indeed traced to select down, but for what fucking reason. I've emailed the dumbass yaton but I bet he won't know, jesus christ.

this four slot idea is just hassle from the very start .. lol! :)

I'm tempted to just cut the track, I can't make any bloody sense why it'd be wired or designed like that at all. sigh

[kernow]

oh this is getting on my titties,

this is the most poorly built piece of equipment I have ever seen, you need to insert it a certain way just so the bloody thing works, and then the SELECT+P2-A issue (I fixed by cutting the tracks so now it only is P2-A)

so I test with a few wires and now , oh fuck this I can hardly be bothered to explain, when I test select up on the card's pins, its now P1-A . this is a joke. :laugh:

[kernow]

I have learned from today to solder when drunk with music on

and that 4 slots fucking suck

put 4 carts in it boots cart 3

bloody hell

at least ABCD/ABCD/Select down is working

sigh

\\o

[gundaRn]

Would it be wrong to suggest you invest in a 1-Slot?

[kernow]

I have two 1-slots.. lol

:laugh:

[gundaRn]

I have two 1-slotsThere's something dirty sounding about that. :wink:

[kernow]

I'm sure I could fit four in one, if I was drunk enough :mad:
