On some tape drives, there is an extra all metal ground cable hanging lose. I remember a guy taking that cable and dragging it over the user port until his c64 was reset. :lol: Yes, that's what I used too! Not that I dragged it over all pins of the user port, but I just hit the reset pin with the c...

The problem is that the programs that run in such huge memory, must be specifically written for them . Unless you use the RAM as a RAM disk for switching in parts of your program or data when needed. That way you could write a program that runs on original hardware (albeit slower) and benefit from ...

I disabled the process with a 37166, 128. What is that for? I've never heard of it. Normally before you alter the interrupts you do a SEI and after you are done you do a CLI. You can always disable interrupts at its source - one of the VIAs. That's why you can also disable NMIs. 37166 is the IER (i...

Are my eyes deceiving me or do you manage to mix the colours to get new shades? I'd like to download that program! Is it available somewhere? I was trying to mix the colors by switching between two colorsets on every frame, but it it only looks good on the picture. In reality the screen is flickeri...

The Vic-20 is "your friendly color computer", therefore it offers the rainbow colors red-orange-yellow-green-cyan-blue-purple in dark and bright. See here.Kweepa wrote:3. A grey in the palette (maybe the C64 palette?)
I would not change that.

@Jeff: Bomberman would be great. Unfortunately it is probably slightly more effort than the simple game I wrote for the demo. @Pedro: Combat looks nice and doable for the Vic-20. Something similar to the plane fight exists for the VIC and was one of my favourite games back then (Of course, the secon...

Basically, the 2400 baud limitation is the kernal, 38k speed comes from software bit-banging the user port. I've seen this done on the 64 so I assume the same could be done on the Vic. As with the IEC-port, Commodore intended to use the shift register of the 6522 for transmission. Unfortunately, th...

In BASIC you write something like: 10 SY=828:LE=11 20 FORI=0TOLE 30 READ A 40 POKE SY+I, A 50 NEXT 60 SYS 828 70 DATA <here come the bytes from 828 to 839 in your case> For a small program like in your example you could just PEEK the values for line 70 from memory after loading the prg, but for bigg...
