Cheat Engine

[Sohail__Saha]

While making a trainer, there is an option to add a background music option to the trainer. However, only .xm format is supported. There is no way to convert .mp3,.wav,etc files to .xm file using a software. It can be done manually but it takes a lot of time. Can anyone say how to add .mp3 files as a background music in the trainers??

In general a trainer would be as lightweight as possible. This would directly oppose that.

I highly doubt adding MP3 files to the mix will ever be a thing for Cheat Engine.

mp3 also tends to come with extra license crap.

Anyhow, you can most likely get/write a lua extension or ce extension that adds mp3 playback

Well then Dark Byte, give a tutorial to "get/write a lua extension or ce extension that adds mp3 playback"

[Dark Byte]

I'd say get a mp3 playback library from somewhere. E.g BASS: http://www.un4seen.com/ (note that while it's free to use you may not sell trainers that make use of it unless you buy a license)

then it depends on what you like better.
You can inject the dll into the target process(or ce itself), extract the .MP3 file from the table to a temp folder and then execute an AA script that sets up the path and calls createThread to a asm routine that initializes the dll and plays the given file path

or
You can write a DLL using the CE plugin api
then either add a new auto assembler command like "PlayMP3" or use the GetLuaState export to register a lua command that does PlayMP3

Or just use the lua extension module straight out to add a PlayMP3 (compile it using the lua library in the svn)

And inside PlayMP3 it's up to you how to use the given library. Perhaps it gets an address, or it gets a filename. Just handle it accordingly


lua command to help: (next version that comes out very soon)
findTableFile('bla.exe').Stream.Memory will get you the address inside Cheat Engine's memory where the mp3 resides.

You can most likely (depending on the mp3 library you use) feed that address directly into a mp3 playback command


Or if this is all too difficult, you can just write a dll with the mp3 embedded in it that plays as soon as the dll is loaded. No need for manual activation. (just plays one mp3, but i'm sure you can always recompile it with a new resource)
