Does this mean that you have to mod the VIC's chipset to achieve higher resolutions? ... we remain at software-only solutions. :) What Mike meant by "unmodded" VIC probably is that some people have added a 3K expansion to their VIC by piggybacking it on the existing RAM in the machine. On...

Hehe :-) Exactly like I thought out during lunch break. My notes attached: 512+480 832-991 = Char: 104 - 123 = Room for 20 Chars 992-1011 = 20 Video-RAM Byte This way the cassette buffer would be used pretty nice. Will try that right now. Let's see if the VIC accepts the change of 36867 in the middl...

Here's a translation of my original reply. However I cut the "fat" out of it that doesn't apply to the graphic mode discussion. Here goes: Same time ago I pondered similar thoughts about using the lower 1K for high-res graphics, but I didn't consider *that* layout. :lol: Yes, I thought of ...

Stumbled upon this thread recently. I remember one of my favorite VIC-20 games back in 1986 was "Penco" - a Pengo clone from the german "64er Sonderheft 3/1986" (Commodore 64 paper mag special issue) A disk image of the programs of that issue can be found here and it includes Pen...

I've always been interested in maxing out the VIC-20 graphic powers. For years I thought 160 * 192 would be the max possible resolution. Then I saw some of the VIC-20 demos that use the RAM in $0000-$03ff and that got me thinking. 128 x 256 is possible with putting the video-ram at $0200 or $0000 an...

Your demo is quite impressive and shows what the VIC is capable of. I didn't mean hidden line removal though, Elite does that anyway. I meant that for each displayed frame only half the lines are drawn at all. You can check this with VICE-C64-emulator and stopping the emulator. Only about half of th...

I've been browsing this forum the last few weeks and this thread got my special attention. I think Elite would be do-able on the VIC-20 by converting the C64-version. The C64 only uses 256 x 144 resolution for the vector-Graphics and 256 x 56 for the instruments. I've grabbed a picture of the C64-El...
