dug out this proof of concept Apple II game I was working on 8 years ago and fixed it up a bit. It's using vapor-lock (vblank detection) and mid-screen mode switching to get some interesting graphic modes on Apple II/II+ (it's not using any of the fancier IIe modes)

this took years of off and on work, but I managed to get the Atari 2600 Myst demake to run on vintage 1980s catridge hardware (essentially replacing the ROM code on a Burgertime cartridge)

Making more progress on the Apple II Peasant's Quest port. Have the archery minigame working finally, this took forever to get more or less playable.

man @StrongBadActual I'm glad the Videlectrix/Sierra merger fell through so we didn't have to suffer trying to play DOS Peasant's Quest with their choice of CGA palette...

I've been working on a DOS/CGA version of the Homestar Runner game "Peasant's Quest" written in Turbo Pascal/8086 asm It's only partly implemented I had planned to do this during the CGA Jam but the semester was too busy so only releasing it now. youtube.com/watch?v=FxjjYfDQ…

I did not expect this to be anywhere near this popular, and of course after posting I noticed a bug in the animation (most noticeable around the cow's tail). Here's a fixed version.

Hey @StrongBadActual I was working on the rain effect in the Apple II peasant's quest video and one thing led to another and in any case here's a cool music video about it: youtube.com/watch?v=DGcj_Xp9…
