@Ivanhoe76: I agree, and no criticism was offered. As Kweepa stated, it's his itch to scratch, go for it!
... and the fact that he's using a 6502 C compiler makes it that more interesting.
@Ghislain: "I recall Jeff D. saying that he feels guilty if he doesn't use Commodore-branded cassette tapes to store his programs. He's hardcore."
No, I think he's just plain whack for using tape.
And, yes, re-typing Killer Comet is still better than using tape.
I had tape, b&w TV, then later added 3k. When I got the multi-slot expansion card, I bought VICMon followed by an 8k expander. Never saw much need to beyond that on VIC.
Three years after VIC, I went the C16 route with a Cardco floppy; at the time, I found that machine more aligned with VIC 20 friendliness than C64. Improved BASIC, ML monitor, 40-columns, more colors, flash, same cool keyboard but with an improved layout, 16K RAM ... it was _everything_ I wished the VIC was and the C64 was not.
Of course, when C128 came out shortly after... it was the crown jewel of 8-bit machines, perfectly keeping that culture thriving through the end of the 1980s.
Very OT, sorry... looking forward to seeing some behemoth orange ball-busting in our near future! If it gets too complex to complete, though, consider slimming it down to do a
Tunnel Runner like game.
