Pretty much complete. Never done anything like this before, so comments are welcome. Things I missed out are: Pots on R,G and B lines, and a dual pot on the L and R audio out. If you can't read my crappy writing just ask and I'll let you know what it says
Heh, Gotta go and buy the parts before I do anything. Another thing I forgot to mention is that I'm using DB15 Neo Geo Style Joysticks. I Can't be arsed to make my own so I'll just buy a NEo Stick.
Sucks if you want to use other arcade boards.At that point, build in compatability for all joysticks, and use the built in ports on the MVS (some boards have it, some dont) for the neo sticks. Best of both worlds there
I have two words for you: Microsoft Visio Have you stopped by the BYOAC forums? I know that a lot of them have done some SCART conversions.
Not quite sure what you're getting at here - It will be compatible with all JAMMA boards - the only reason I'm using Neo Controller ports is that A) it is unencoded, so easy for me B) I can easily buy a neo stick, and not have to build one (which I would be terrible at) Not sure what you mean by all joysticks? I could always build A different joystick - I'm just too lazy! Damn, Visio would have been good for that. Oh well, live and learn I guess! BYOAC Forums - sounds like a good idea...
Im saying, build it using the parallel ports. Itll save you time when you want to play 6 button games later on. Plus, if you want to play neo, just plug it into the neo. Its not so much trouble for building a 6 or 8 button joystick, especially after you build this thing.
Ahh, fair point. Although I have 2 spare pins on the DB-15, So I could always use them and build/mod a controller. Or use a DB-25 and build an adaptor for neo controllers. The only reason I'm so set on using neo controllers is that it means I don't have to build a stick - which I think would be shite.
I'm having some trouble with exactly this... I intend to build one supergun for use with my MVS, CPS2 and ST-V.... the latter two both use 6 buttons, but using different on-board connectors. I'm soldering a DB15 directly to the Supergun, which I'll use directly for the MVS, and I'll probably build some adapter boards later which pass the additional buttons on to the ST-V/CPS2. Oh and I'm having terrible colour bleeding on the ST-V, what should I put on the RGB lines? I tried 220uf caps (as they were in the cannibalized DC RGB lead I used) but it made no difference...
Yeah, I have that problem with my Speccy too, but I have no caps on the colour lines. I think it may be an issue with the composite sync voltage being too high, or *something* else, but I could just be talking shite. I should get out the ol' multimeter and compare the voltages from my DVD player or something...
My ST-V outputs the video signals at 1Vp-p instead of 0.7Vp-p like most other boards. I fixed it with a SCART socket, a SCART plug, three pots and lots of wire, though it's a pain to get the colours adjusted correctly. I have a few spare double-sided JAMMA fingerboards (the ones with a gap in the middle, for adaptors and the like) so when I next have some spare JAMMA edge connectors I might make up a little adaptor with trimpots on the signal lines. The middle pin goes to the Supergun, then the two ends go to the board and video ground respectively. Silvergun looks gorgeous once you cut the brightness down a bit Stone
anyone got a advice how to put in a supergun also the extra soundconnector thats used for example on the konami m2 jamma boards ?
If you mean a line-level audio output I have a convertor I picked up from Maplin for about £6 which I never quite got around to adding Basically you give it power and the speaker-level amplified audio from the board, and it converts it into a pair of line-level outputs for you to plug into your normal speaker amp with. Easy enough to fix up Stone
Bastardo! I want Silvergun :smt071 But thanks for the advice, I was wondering why Astra Superstars looks so damn shite, I'll mess around with the pot idea. Which ones should I get?
