Re: WIP: Manic Miner port
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 ...

Dragonwing 2
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...

Re: 10-Bit Oscillator Frequency Resolution
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

Re: 10-Bit Oscillator Frequency Resolution
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...

Re: 4ty - 40x25 interlaced text mode on unexpanded VIC 20
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...

10-Bit Oscillator Frequency Resolution
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 $...

http://i.imgur.com/pMT0KJ2.jpg http://i.imgur.com/pydhwf8.jpg http://i.imgur.com/Cb2R7KB.jpg There's a bunch of 40 column programs created for VIC, but I believe this one is different.

Re: Maxi-/Uber-Edit
Great work Tokra! I was actually a bit surprised that all this could be done without hacking the ROM Of course, people have done 40-wide screen routines before, but this one is much more useful, because it's fast!

Re: WIP: Vicious SID Converter
Great converter, Kananga! And a nice pack of songs from Tokra too. Has anyone else successfully converted other SID tunes recently? I've just "ported" the Sid Vicious code to C64 and optimized it for pulse waveform only - (NMI no longer needs x-register and C64 NMI doesn't need to jump thr...

Re: New release: Dropout
Very nice game and highly polished to make it playable! Of course this: - PAL version does a graphics hack to display 12x8 pixel square blocks interests me the most. From what I can see you mean 8x12 pixel blocks (x by y) not 12x8. I see from a quick peek in the VICE-monitor that you seem to flip-v...
