Re: cheat lua plugins
A plugin starts before anything is loaded. You need to use register_start to get a callback once the emulation starts.

Re: cheat lua plugins
> [MAME]> manager.machine.devices[":maincpu"].spaces["program"].install_read_tap(0x2000,0x2fff,"test",foo())
foo() is calls foo and install_read_tap gets the return value from foo() (nil) as the tap callback function.

Re: cheat lua plugins
What are you trying to do? That's beyond the scope of cheats but luaengine supports adding taps which can allow you to get a callback when a memory region is accessed.

Re: cheat lua plugins
I was hoping that wouldn't happen but thankfully it's not a big problem. Screen height is a property now so changing screen:height() to screen.height should fix it.

Re: cheat lua plugins
Lua cheats are part of the cheat package. If you use the plugin they will be listed in the Plugins-Cheats menu otherwise they are ignored.

Re: HELP!! CHEATS NOT WORKING----NO OFF/OFF SWITCH, JUST CODE'S DESCRIPTION!!!!!!!!!!!
Sega cd rom cheats don't make sense. I don't know the old cheat format but I suspect the two latter ones are ram cheats in the sega cd address space, maybe use segacd:segacd_68k

Re: Intel .HEX to cheat converter?
Interesting. You could write a script for the lua plugin that would load the hex patches directly but the result would only be usable with the plugin, otherwise there isn't any existing mame feature to convert intel hex files to xml cheats.

Re: Intel .HEX to cheat converter?
As far as I know there's nothing like that anywhere. I'd like to know what you are trying to do though because I'm not sure what kind of cheats you could get from a hex object file.

Re: cheat lua plugins
Is it possible to change the way it works so that it looks for a match using the 32K block size first (58ef,d8ef,158ef,1d8ef etc) and then falls back to a 8K block size (18ef, 38ef, 58ef, 78ef etc) if it can't find a compare value match on the 32k block size. Sure, this isn't hard. What to do with ...

Re: cheat lua plugins
This isn't possible in a general way. It is potentially possible for all the software on a particular hardware platform in lua but not with the cheat engine or finder.
