Re: [vigilant] Get points not just by defeating enemies, but by hitting them

I'm terribly sorry people (both necro-reply and misunderstanding). I just didn't think that as time went by the main rom of the vigilant romset was going to change. To sum up, the aforementioned cheat applies to vigilantu - The US version (1 I assume) of the rom (I tested on a mame 0.156 on windows)...

[xevious] Some cheat to play around

Hi there people, I wanted to post these cheats I've been working. I hope "at least they're not buggy" (i.e: executing an invalid opcode, resetting the game, getting it stuck on a infinite loop, etc). Here they are: With this cheat you hold the bomb button and it'll make some sort of "...

[vigilant] Get points not just by defeating enemies, but by hitting them

Sorry Pugsy for bugging you with those "Skip Checksum" cheats some time ago. Now after some very long time I've started to write cheats that may be useful. For example, in vigilant you don't get any points by hitting enemies, and the points got are few. Here the there are 3 cheats that mak...

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 th...

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 h...

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...
