any character that could be typed at a c64 keyboard is legal.

If my analysis of the decoding tables at $EB81, $EBC2, $EC03 and $EC78 is correct, These are the bytes that can't be entered from the keyboard:

$60,$61,$62,$63,$64,$65,$66,$67,$68,$69,$6a,$6b,$6c,$6d,$6e,$6f,$70,$71,$72,$73,$74,$75,$76,$77,$78,$79,$7a,$7b,$7c,$7d,$7e,$7f,$80,$82,$84,$8e,$8f,$e0,$e1,$e2,$e3,$e4,$e5,$e6,$e7,$e8,$e9,$ea,$eb,$ec,$ed,$ee,$ef,$f0,$f1,$f2,$f3,$f4,$f5,$f6,$f7,$f8,$f9,$fa,$fb,$fc,$fd,$fe

As far as I can work out, those "illegal" bytes don't appear in the embedded strings, so it's all perfectly legit.

It's a bit of a cheat (wasn't "no illegal characters" a requirement? But that begs the question: What does "illegal characters" entail?), but I just love it how he manages to put the binary encoder AND a progress counter into merely 2 lines. I was also wondering why he started with 40, wasting several bytes, until i noticed that line 41 is actually part of line 40, and he just made it to look nice! ;-)

Also: Why was this added to CSDb and 4bit mess and 6bit mess not? 8) They're even better!

Awesome shit.

Is it a basic depacker that recreates the machine code ? atleast there's runable asm routines in memory after the "depacking". nice idea.

No way anyone could pull this off in pure basic, not even xbow :-D
