Emulator Cheats

Even if each game has its specific hardware, fortunately the cheats are the same :) tazmania, tazmani2, tazzmang : <cheat desc="Clear Room Now!"> <comment>This doesn't work on bonus rooms</comment> <script state="on"> <action>maincpu.pb@8558=02</action> <action>maincpu.pb@819D=00...

it's funny that you can find some new cheats and corrections for games that have been in MAME for ages ! Yes, there's always going to be plenty of scope for bug fixes and new cheats even for those games that appear stuffed to the gills already. When I wrote 'you', I was in fact thinking about you (...

Thanks a lot for the update and happy new year 2010 !

First the "Play all levels" cheat : <cheat desc="Get All Dolls"> <script state="run"> <action>maincpu.pb@C314=20</action> </script> </cheat> I'm not sure exactly about how it should be named, but this cheat is required so that the game doesn't end after Area 7 Round 4 i...

Some more observations 1. The poke value returned by the cheatlist command should be the first value rather than the current value (as it's what you desire most of the time). So, if you do start a lives search when you have 5 lives and find the result when you have 2 lives you'd expect it to show s...

Even if I haven't tested your additions (I can't even compile them yet), I'm very impressed (and of course happy) to see that you've added in an easy way what we expected from Aaron since last year and the change to XML format :) Before you submit this to MAME Team, here are a couple of things to do...

WOW ! How do you find out that time is frame-dependant ??? It's a known issue that happens in many games ... To check this, pause the game, initialise search, go to next frame (Shift + P), search for values decremented by one, repeat until you find only one value ... Note that such "trick"...

Little reminder : this topic is supposed to talk about new cheat databases or XML files releases, so if you want to discuss about non-working cheats, if you have some requests, or if you need some help, please use the other boards ... Note to Pugsy : I think that only "experts" shall be ab...

Using the beta .dat file for mame 0.127, samurai showdown gets a work ram error on startup. It's definatley from the cheats because turning them off fixes it. I'm unaware of the new xml format but I'm assuming there is a code on that messes the game up. Not sure how to fix it, but thought I'd post ...

hi everybody, I've found some bugs in king of fighter 2003, 2002,2000, 97 and in last blade2: kof2003: every time you choose to play with a boss character you will find a rom error: kof2002: rom don't work when the cheats are active kof2000: rom don't work when cheats are active kof97: rom don't wo...

Pugsy the F6 button doesnt work, if i want to deactivate the cheats of every game can you fix it? Pugsy can't fix it (he only works on the cheats, not on the functionalities), but he could report the bug on MAME Testers so Aaron can have a look .. Well it's not actually a bug at the moment...as I s...

When I turned on Strider 2 on mameui32 v0.127, I get this message: strider2.xml(5): error parsing cheat expression "main.pb@C3628=09" (invalid memory name) All I'm asking for is a "fixed" xml of Strider 2... There's a MAME problem with all games in zn.c driver (see MAME Testers ...

Full list checked, there are fortunately no other problems like this

Thanks, that looks like a real bug....easy to fix, in the meantime you can change the sub. to user1. (apart from in the sound test cheat) in the xml - that should work. I was about to post the same thing ... I can confirm that all refs to "sub." shall be replaced by "user1.", wi...
