Wiring a 49way as an 8way - switchable
MonMotha:
What you want to do is map all of the 49-way outputs to 8-way outputs (or 4-way, if you prefer). This can be done with a bunch of combinational logic. Draw a 49-way grid, figure out what mapping you want to the 4 output signals, come up with a Karnaugh Map for that, minimize it, and implement with 74 series - OR - write some HDL and synthesize it to a PLD. Should fit on a GAL22V10 or thereabouts.
Oh, if you'd like, I can whip this up for you for a few bucks.

Does not!
Arch Rivals uses a standard resolution monitor.

I looked it up in the manual, it uses medium res.

Funny, I just had a look in the manual at:
http://www.basementarcade.com/arcade/library/manuals/a/ArchRivals.pdf
..and it looked to me like Aaron was right and I was wrong. KLOV says standard, although they've been wrong before. Still, I was convinced enough that I even went and edited a few old posts of mine where I was telling people it was medium res.
But I know I got that medium res idea somewhere, and now you say your manual says medium? Very confusing. :dizzy:
Aaron, since you're you, I'll assume the version of Arch Rivals in MAME is definitely running standard res. Now I'm wondering if there's another version of the PCB out there that outputs medium. Or maybe just some copies of the manual that are incorrect. :dunno
