programmable function keys, fixed C128 keyboard extra keys
Turbo Tape 64 (LOAD only)
JiffyDOS (with 1541 - slightly slower than original one, unfortunately)
bugfixes and various improvements
All similarities >3 explained in the last commit.
BTW, I had to disable the Retrofan Mega65 logo again - depending on the RAM content (filling bytes) it triggers a bug in the screen editor, where printing a character in the last column can even crash the ROM. Bug is probably very old (can be observed on the last ROM revision before I started development) - I'm going to investigate it, but not in this 'sprint', there is enough changes in this pull request already.
In short:
