this file loading code is broken. it tries to load the file in 64kb chunks but it only saves the size as a 16bit variable, so a 64kb file will be recorded as 0, and any bigger file will break.

but fortunately the file is only 11kb so it works, as the read-second-chunk behavior never triggers

at least this is a compression algorithm that isn't too complicated: it's simple RLE.

0xFF is a marker, and is followed by a byte of repeat count(-1) and a byte of value.

although technically this is the second time I hacked this compression, I did figure this out already back in, like, 2013?

this game uses a ton of hardcoded offsets into data files. I wonder if this was done with linker nonsense or if they had to be manually hardcoded in.

the latter is frighteningly possible

@foone@digipres.club that's good, I guess...
