looking for executable unpacker for ArcR format

jotd · 22 March 2020, 10:02

Hi,

Trying to decrunch Liberation / Captive II executables, but xfddecrunch doesn't recognize this format.

Disassembling the code shows only garbage except for the startup (jumps to the last hunk) and the last hunk which decrunches & relocates the first hunk (others I don't know)

I could manually unpack & save the main program, but now the small program is the same. I was wondering if there was a clean solution like xfddecrunch, or if I missed something.

xfddecrunch knows "ArcR" fourcc, but not as executable.

The packed executable: Liberation.zip

bump bump.

Seems that this game was cracked. Comparing crack & IPF original, both executable files are different, and the cracked executables (DELIRIUM) seem to have been repacked by the same ArcR cruncher.

It probably means that such an unpacker + packer exists.I know ArcR exists, but not as executable, with hunk reloc, etc... like a lot of others (powerpacker, propack, imploder...). I'd very much like to get hold of it.
