Any tools to decompile .luac files?

[gregsadetsky]

Thanks for this list of tools!

Would you be able to recommend tools that work on macos and allow decompiling / disassembling of .luac files?

Thanks!

Hey! I had some flakey success using unluac with these patches by zhuowei:

However, Panic has since changed the Lua version shipped with more recent versions of the firmware and SDK, so your mileage may vary

Thanks for the quick response!

No worries! I should say, I haven't spent a whole lot of time trying to decompile Playdate Lua yet (compilers and decompilers are... not my forté), so if you find something that works well please give me a shout!

I'll also make a note to reply to this thread if I ever take a deeper look into it.

I patched the Java applicaton unluac to decompile all known Playdate Lua bytecode files, including the ones with a standard Lua 5.4 header (and, as it turns out, opcodes appended to the end of the ORDER OP enum):
