Downland for Sega Genesis, Day 9: first playable version, seen here on hardware. Still lotsa work to do! #downland #tandy #coco #sega #genesis #megadrive #sgdk

Downland for Sega Genesis, Day 8: had a busy day so only worked on it a bit. Now exporting the character font. Not used in game yet. Hopefully tomorrow will be a bit more productive. #downland #tandy #coco #sega #genesis #megadrive #sgdk.

Downland for Sega Genesis, Day 7: got background drawing up and running. Out of chocolate so back to the couch! #downland #tandy #coco #sega #genesis #megadrive #sgdk

Me: it’s Friday! Let’s work on the project!.Also me: no. Leave me alone. I want to couch. Me: I’ll bring chocolate!.Also me: ugh. fine.

Downland for Sega Genesis, Day 6: more work on the resource extractor and it’s almost ready for use. Light work session otherwise #downland #tandy #coco #sega #genesis #megadrive #sgdk.

Downland for Sega Genesis, Day 5: continued on the resource extractor. Now exporting a dedup'd tileset from the game rom, and started on saving tilemaps as .c/.h files. Still a day or two from displaying them in the game. #downland #tandy #coco #sega #genesis #megadrive #sgdk.

I'll eventually break down the images into a dedup'd tileset and tilemaps.

This will also be useful for the Sega Master System version.

Downland for Sega Genesis, Day 4: For extracting background and sprite graphics, instead of doing it at startup as before, this time I've started an offline tool to generate assets at compile time. #downland #tandy #coco #sega #genesis #megadrive #sgdk

This is the. (counts on fingers). eigth platform I'm porting Downland to. The todo steps are getting too wellworn now. Do background drawing, then sprites drawing, then handle input, handle transitions, handle sound. I should switch it up to keep it interesting.

Downland for Sega Genesis, Day 3: Just some housekeeping today. Spruced up makefile, updated other platforms about an API change, added stub game runner and joystick handler code. Nothing fancy. #downland #tandy #coco #sega #genesis #megadrive #sgdk.

Downland for Sega Genesis, Day 2: Integrated Downland game code in the SGDK sample. Successfully loads game resources. So far so good. #downland #tandy #coco #sega #genesis #megadrive #sgdk.

Downland for Sega Genesis, Day 1: Getting back into the SGDK. Adapted a sample project and got it running. Looking good for the sound situation as it natively supports multiple wav file playback. #downland #tandy #coco #sega #genesis #megadrive.

Downland for Sega 32X running on hardware. #downland #tandy #coco #sega #32x #sega32x

I can't tell you what actual the problem was. I'm sure some code in the MD crt.s was modifying the COM ports for some reason. I'm very much not an assembly guy so when I found a working example, I swapped out everything blindly hoping the problem would go away. And it did. Phew!.

Downland for Sega 32X, Day 11 supplemental: And with that, I do believe the 32X version of Downland is complete. Let the rejoicing begin! #downland #tandy #coco #sega #32x #sega32x.

Downland for Sega 32X, Day 11: Couldn't figure out why the joystick state kept getting reset every second. Swapped out the entire MD code and with a much simpler version and the problem disappeared. Crisis averted. #downland #tandy #coco #sega #32x #sega32x.

Maybe it's related to how it waits for vblank. It's different from the sample app.

Downland for Sega 32X, Day 10: investigating glitchy joypad state. Reading at 60fps is flaky, but 30fps is stable. But a separate 32x sample app has stable joystick state at 60fps. Oh come on, lady. #downland #tandy #coco #sega #32x #sega32x.
