As a short notice: I've released a fun little demo for the 2600 on the demoparty "Deadline" that happened last weekend in Berlin.

 

Here's the Pouet link: https://www.pouet.ne...php?which=71871

And here's the link to my little website containing source code and other stuff: https://xayax.net/2k_is_no_limit/

 

It's implmented for a PAL machine, but this should be my first demo, where porting to NTSC should be doable.

 

Hope you enjoy running it as much as I did making it.

Are all of the ROMs for the Atari 2600 listed on pouet.net demo's only??? I don't think I've seen an actual homebrew "game" posted on there.

The site is demo orientated, but there are a few games in there as well, the most sophisticated probably being Assembloids2600:

Do you plan to do the NTSC port yourself?

Not very soon. Right now, I've got to attend to other projects and also clean up my website, add some cartridge labels for my releases, etc. And I'm not very sure that there  really is a demand for it... I also noticed that I already did an NTSC capable demo: http://xayax.net/plasma/ can be configured via the difficulty switches: 50/60Hz and PAL/NTSC palette.

 

The 50Hz vs 60Hz timing shouldn't be much of a problem, colors neither. The main effort will be the music. It might need some workover, but I'm not a musician. If you would like to give it a shot, let me know via PM, and I'll explain how I did the conversion of the generated dasm assembler to ca65.

Couldn't you simply update the music in fractional frames? It is updated every 4 frames, right?

 

Then, for PAL, you would have to update every 4/60*50 = 3.33... frames. This can be achieved by adding 256/3.33 = ~77 to a variable (e.g. tt_timer) every frame. And when the carry is set afterwards, it is time to update the music.

 

And, to stay in sync, you would have to do the same with all animations of course.
