Re: redefine the charset

On unexpanded machines I usually do the reverse, with my redefined chars at the front of the charset and the rom font at the back: POKE 36869,255 to set the gfx ram looking at 7168 onwards. (With the screen still at 7680 as usual, giving me 64 redefinable chars and both are right at the end of memor...

Re: "Orb Megademo Deluxe" - Vic-20 Megademo remastered for 2016

Incidentally I'm experimenting with a cross-platform tracker using the music driver from this. Here's an example video (Again I can't get the youtube link to work which doesn't seem to be a problem elsewhere)

Re: SJLOAD-20 source code anybody?

Re: Reinventing sprites?

Yeah you can totally use a lot of that first block for sprites. My Astro Nell game a while back has the map chars at $0284 and the softsprites at $338 onwards. (I had 4 of them up to 3x2 char size I think, didn't ORA the background because they were hires and I had to shift the X position in real-ti...

Re: Vic 20 Cynthcart or similar?

Aleksi wrote a small monophonic organ a while bacxk that can controlled with the keyboard. It's in assembler so there's no latency.

If you go here and download demodisk1 it's the file called "CNCD ORGAN"
