Re: Double buffering screen bitmap
Clearing an entire bitmap is slow... In "Back in the Good Old Days" demo from 2004 I allocated chars dynamically (like a ring buffer) when drawing and eor-filling the frame. Char 0 was used for empty screen, so I only needed to clear ~200-256 bytes to wipe a screen buffer. Dynamic char all...

Re: Multipaint VIC 20 support
Perhaps an incomplete, multicolor-only MG mode would be still easy to add - and very useful for VIC 20 people... Multipaint saves also to some native formats, so it could have an option to save MG picture file. You could then do some hires edits/additions in Minipaint on VIC Having mixed hires&m...

Re: Multipaint VIC 20 support
Good points there Mike, and I fully agree about the limitations and the OS friendliness issues. Please send Dr. Terrorz a spec of MG format and an executable viewer (email at bottom of page http://multipaint.kameli.net)! You can tell him I totally recommend adding MG support as well :) (and there's ...

Re: Jeff's VIC 20 Book
Great work! One thing I noted: Page 117: Block-Read and Block-Write commands. B-R and B-W are said to be buggy and they should be always replaced by U1 and U2 respectively. However, I don't know what kind of bugs they have and if that only concerns C-64 and not VIC 20. Maybe someone else can clarify...

Lazy LZD Data Packer
Lazy LZD Data Packer is a C64/VIC 20 frontend for the minimal LZ compressor LZD I wrote two years ago for a specific purpose - fast decrunch of data from VIC 20 cartridge ROM. I wrote Lazy now, because I was too lazy to load, crunch and save files manually while working on a new C-64 game. lazylzd-v...

9-color Block Graphics BASIC Extension for Unexpanded VIC 20
When I got my first computer, a VIC 20, in December 1984, one of the first BASIC commands I tried was PLOT. And was I a little disappointed when my little friendly computer didn't recognize this command at all. 37 years later I got the idea to write a BASIC extension with block graphics and a PLOT c...
