Hunkster
I found a neat little program hunkster, written in Free Pascal, to create an Amiga 68k Hunk file of a given file, which can be linked to your program, very nice if you want include everything into the Executable. The program was made for Windows only but also compiles without problems on Linux. The command line version of it also works out of the box on Amiga. In principle one could even compile the GUI version with the Amiga MUI-LCL but its far too slow and buggy, therefore I wrote a little MUIClass application which does the same as the LCL application.

Downloads:
- Amiga Version (OS3.0+, MUI3.8+, 68020+)
- Linux Version (x86_64)
My source is on github as well.
