If you are having problems finding or using cheats for an Emulator (particularly MAME/MESS) or have found a trick that you wish to share this is the place to do it. But please read the Cheat FAQ first.

Quick way to test cheats?

Post by txcdxkqu »

Is there a way to just write the cheat code at the debugger window and have it take effect immediately?
Closing and reloading the rom every time I want to test out a cheat is too time consuming.

yes, here are examples:
first line represents the cheat in xml file, following line(s) are equivalents in mame debugger.
first example is a RAM cheat; other ones are ROM cheats.

<action>maincpu.pb@1092CD=01</action>
b@1092cd=01
rb@1092cd=01

<action>maincpu.mw@0BC74=4E71</action>
rw@bc74=4e71

<action>maincpu.mw@03FD8=0300</action>
rw@ff81fec0=0300

You can also use the reload cheats feature in the cheat menu. Edit txt file, save, reload cheats, cross your fingers and hop that you didn't make a fatal XML syntax error.
