Imploder exe/data files cruncher/decruncher. Based on the reversed implode/explode routines from lab313ru.
Imploder packs quite well, the decruncher is relatively fast and can decrunch in-place without any overhead.
It can pack Amiga executables, X68000 executables or plain data files.
Packed executables use "overlay" depackers:
A forged header instructing the OS to only load a fraction of the file (just containing a 2nd level loader and a data depacker), the exe then loads, depacks and relocates the data it contains "in place" thus only using a very tiny amount of memory overhead.
68000 asm decruncher taken and improved from a Team 17 game.
Windows and Amiga executables provided.
