10 years ago the guys from the demogroups wAMMA and Trilobit tried to build a cartridge that runs 6 different already released demos together with a newly coded menu.
9 years ago they gave up and released their stuff unfinished as a cry for help.
5 years ago I was asked, if I could try to fix it finally. I succeeded, but for other reasons it never was completed.
Well, until now.
The whole story is available at https://xayax.net/nonxayax/triptych/, including an option to run the demo in an emulator running in your webbrwoser.
The coolest part about it: a cartridge will be available in the AtariAge store soon.
("demo" in this case demonstrates cool coding skills as a non-interactive animation, and not some kind on unfinished game)
