Emulator Cheats

The simm only sets you can use simmx.x.mb where x.x are the slot numbers (in theory, this might not work because of the period in the name) to set a byte in the rom. For the sets with a cdrom, there's no way to edit the simm data with the built in cheat engine. You'd have to use the Lua cheat engine...

I can help with the cheat engine part, the encryption is outside my skill set.

It's worth noting that you should use the standard cheat engine rather than the plugin one, as the o region isn't being poked with that as the Hit Anywhere cheat doesn't work. Fixed. Edit: The opcode space likely won't work for changing the midi data because it's data and opcode space is only valid...

Here's two codes for tiger gauntlet. <mamecheat version="1"> <cheat desc="Infinite Life"> <script state="run"> <action>maincpu.pdb@4a=09</action> </script> </cheat> <cheat desc="Walk though walls"> <script state="run"> <action>maincpu.pdb@1c=0f</acti...

You can try to make a pull request for that if you want I suspect it would not be committed. It'd be simpler to change the cheats and hiscore entry to use "mastercpu" instead.

mastercpu not maincpu.

Thanks for doing these. I did one as an example but didn't have the time to do the rest.

Watch will display the real time value of a given address so you can watch how it changes as you play.

>Suppose we obtain only a result............ on result i can select... i have pick a screenshot: The numbers there are address, value 1, value 2 (value 1 is the right operand and value 2 the left). Notice is says "Value is difference" which means it will only get matches that differ by the...

When you start a new search, the contents of the selected cpu ram or ram region are saved. Then you can compare the current or a selected past save (use save current to store another ram state) use the operators. The left and right operand numbers are a list of the states that have been saved and th...

Added input sequence cheats that sequenced button presses. Limitations, only works from a key binding (not from menu), any button presses will work as normal so may interfere with the sequence and analog inputs can only be full off or on. Here's an example that does a Hadouken to the right in sf2. S...

I think this is your problem. cheat.7z is considered a subdirectory by the mame file open code so you need to create a new subdir called cheat in the dir where cheat.7z is and put the cheat.simple file in there.

You want to be able to access registers too? That's doable, I'll get to it when I have a chance. Edit: added as cpu.regs[reg].value Anyway, bp 1234,1,{pc=1280;g} would be like cpu:bpset(0x1234, function() --[[do something here]] end) and wp deadbeef,1,w,(A==90||A=00)&&pc=1234,{pc=1280;g} wou...

Are you checking for the cheats in the plugin options menu? The cheat menu is only for the builtin cheat engine currently. (I also posted a huge game genie list here if you're interested)

Added very untested break/watchpoint support (in head right now but won't be part of .188 but .189 instead). If anyone actually uses it, be sure to let me know about problems.

There are changes to cheat/init.lua and luaengine.cpp so unless you can build mame yourself or get a recent build from someone you'll have to wait until the next release.

Now you can set hotkeys similarly to how the input menu works. It doesn't let you set multiple mappings for one cheat (which wouldn't make much sense IMO) [strike]and doesn't currently give feedback when polling except the game freezes for a second[/strike]. Added a popmessage when to press the hotk...

Added to the ui joystick hotkey binding.

You can set it to a stick by editing the hotkey json file directly. JOYCODE_1_BUTTON1 is the first stick first button, I'll think about how to work that into the UI but it'll currently not be possible to set a key or button by pressing it like the input config.

Made a one bit error, fixed now. Also added the ability to link cheats by replacing the description with a ^.
