Couldn't resist. Here's a quick 64x32 text routine with full 7-bit ascii. load"miniascii.prg",8,1 sys10240 to run some test code where you can type text and move cursor (destructively). Also checks return and clear/home keys test.png Memory map: $1000-$10ff screen matrix $1100-$1fff bitmap...

Interesting project! I would go for 192x160 display and 3x5 font on VIC 20. ALL CAPS and text-on-every-line get a little messy, but when the text is mostly a mix of uppercase and lowercase letters then it's still... somewhat readable. Fitting a few more lowercase letters like c, s, and z to a 2x4 bo...

Another Bunny Basic example program, a simple breakout clone. Unexpanded VIC 20. Load Bunny Basic interpreter first: LOAD"BUNNYUNEXP20",8,1 POKE56,24:NEW Then load Breakdown and start with a RUN. 1 sys6144,2:end 2 clr:gosub900 3 pokew,32:y=y+n:w=y*22:w=w+x:a=peek(w):ifa>32thengoto90 4 w=w+...

I remember this one. Charming!

Bunny Basic is a fast, very limited, integer-only basic interpreter. It's partially compatible with CBM BASIC V2, so the code should look immediately familiar and you can also "slow-run" most Bunny Basic programs in CBM BASIC V2. There's some additional features in Bunny Basic though, such...

Bunny Basic Bunny Basic is a relatively fast, limited instruction set, integer-only basic interpreter for Commodore 64 and Commodore VIC 20. It's partially compatible with CBM BASIC V2, but there's quite a few restrictions. However, you can run most Bunny Basic code in CBM BASIC V2 interpreter, it ...

For example in 0.5K or 1K minigames and such, sometimes all you need is the smallest random number routine. Here's a handy one: Random subroutine lda #$01 asl bcc .1 eor #$4d .1 sta Random+1 eor $9124 rts It's just a simple 8-bit PRNG, but the output value is shuffled with timer bits. Why? 8-bit PRN...

Haha, very nice. Good work!

Very nice! Better than original. Maybe try call the voice frequency adjust routine 2-16 times more often (set up a timer interrupt) to make the tones stable - it would steal only a few dozen cycles :) (If you need stable raster waits, you can always 1) wait for the previous line 2) then temporarily ...

The best way to halt a project for a year is to talk about it in public, but here's some sketches of Dragonwing 2 :) 1 multicolor pixel smooth scrolling works! (Look closely at the tileset character pairs and you'll get it). Unlike the first Dragonwing, this one will be PAL/NTSC-compatible. And 8-16...

Very nice! :D 10 bit test Hello please check this music that I wrote to try your corrections. and tell me if it's okay. For the songs already written I have to change the value of the note too that in your table is different. from those used in 8-bit for Pal thanks greetings Armando 10bit-pr.prg.zip

You're using it wrong... Your program only sets the high 7 bits of frequency, so there's no difference from normal VIC frequency resolution. You need to include also the low 3 bits in the data for each note - the small values 0-7 in the frequency table at start of this thread - and write them to the...

For NinjaTerm I would use a full screen bitmap with 8x16 chars, but arranged and wrapped around in a way so that you can scroll the screen very fast. Odd lines can be scrolled up by just changing the value of screen y-position and wiping the top line (8-high). Even lines can be then scrolled up by r...

One of the most annoying things about VIC 20 is that the music all too often plays horribly out of tune. This program improves the frequency accuracy of square voices 1-3 from 7 bits (0-127) to 10 bits (0-1023). Fantastic! :D Download: http://www.cncd.fi/aeeben/download/10-bit-ofr.zip To init: jsr $...
