What is *.rpk / *.class from Street Legal Racing Redline and are there programs that reverse engineer file formats?

 

Samples:

https://mega.nz/folder/gP4h2QCB#A1hMulJDGXYbtwHl0DPuuQ

rpk:

4bytes magic (PPAK)
uint unk (ver? 512)
uint num
uint zero

foreach num:
	short zero
	short index
	60bytes label

uint blockSize
uint num0
uint zero
uint num1

foreach num0:
	22bytes unks (2short, 2int, 10bytes unk?)
	ubyte lenStr
	bytes[lenStr] label

if curPos < fSize:
	bytes[toEndFile] txt
                  	

and PY script for parse *.rpk

Do RPKs from Street Legal Racing: Redline also contain map models?

no one make a tool to convert map models from street legal rpk to obj and start a map editor?

I fear you'll need your personal tool creator.

Specifically, making a "map editor" would require ages and thus they are very rare, imho, maybe one per a hundred formats.
