Has this happened to anyone on [gladiatr]/[ogonsiro] in mame 0.193 or above

Hi, I was testing [gladiatr] and [ogonsiro] and right after the game boots a credit is inserted. This behaviour is shown in vanilla versions of mame 0.193 and mame 0.194. What could be causing this problem in the driver? A lot has changed since 0.181. When Vas Crabb added that change in the MCU some...

Re: Cheats in [flower] (now that driver is rewritten)

Hi, I wrote some changes in mame\drivers\flower.cpp and changed all ocurrences of "mastercpu" to "maincpu" and the cheats and hiscore works flawlessly. BTW, the hiscore plugin seems to write only when it detects changes in the memory areas it points to, so if you just open and then close the game to...

Re: Cheats in [flower] (now that driver is rewritten)

MCFG_CPU_ADD("mastercpu",Z80,MASTER_CLOCK/4)) mastercpu not maincpu. Should I change all the ocurrences of "maincpu" with "mastercpu"? Or just that line? Also, the line you mention was: MCFG_CPU_ADD("maincpu", Z80,4000000) /* ? MHz */ The clock frequency is hardcoded. Looking forward from reading y...

Cheats in [flower] (now that driver is rewritten)

Hi, I've tried doing simple cheats with values I found on the debugger (mame 0.193), for instance, with ci, cn eq,0, cn eq,0 (multiple times without inserting coins) and then cn eq,1 (inserting a coin) and cn eq,3 (inserting 2 coins) and then pushing the 2nd start button and then cn eq,1 I determine...

[twincobr] Skip Checksum cheat

Hi, I've been trying to find a cheat that skips all the checksum verification code and starts straight to the title screen. I know that the title screen code start about $201ae. I've tried jumping there but there seem to be a couple of conditions in the registers so it doesn't end in an infinite loo...

Re: Again the same problem reading an adrress in [mutantf], but a little different way

Oh, I see. So, there isn't any way to reference the address just to "watch" the value? I don't know if there's a syntax to reference the ioprot address apart from "maincpu.pb" (something like "ioprot.pb"). Just throwing ideas. I've a self compiled mame build of 0.174. Maybe I'll have to redefine the...

Again the same problem reading an adrress in [mutantf], but a little different way
