Exception in thread "main" java.lang.IllegalStateException Lua 5.0

Hello i encounter an error when decompiling lua scrip 5.0 using unluac.jar

Exception in thread "main" java.lang.IllegalStateException
at unluac.parse.BHeader.<init>(BHeader.java:28)
at unluac.Main.file_to_function(Main.java:55)
at unluac.Main.main(Main.java:34)</init>

here are the lua script;

It was compiled with MAXSTACK 300 which for Lua 5.0 changes the way that certain bytecode instructions referencing constants are encoded. (It sounds like you're maybe using an old unluac version as well, but that's neither here nor there.)

It's easy to adapt unluac for this change:
