Currently reconsidering that TG-16 version. I'm feeling the tired. The NES version wore me out.

Gonna start looking at the TurboGrafx-16 now, using llvm-mos again if I can. I think that'll be the last port on the checklist I made myself. Or at least, it'll be the last port of the year.

Downland for NES Day 18, con't: Improved the sounds. I'm pretty much done, I think. I wanted to convert the game from regular unrom to unrom-512 but can't find a good example. I'll leave that for the future. #downland #tandy #coco #nintendo #nes

Downland for NES Day 18: Made the set of sounds for the game. They sound... not great. But at least I have something. #downland #tandy #coco #nintendo #nes

Downland for NES Day 17, Con't: Managed to make crappy sounds for running and climbing and they seem to work fine. Finally some positive developments! #downland #tandy #coco #nintendo #nes

Downland for NES Day 17: Managed to get a sound effect working. Turns out with famitone2 you can't have sound effects if you don't have music. Considering that only music loops I think I'll use that as the run/climb sfx. #downland #tandy #coco #nintendo #nes

Downland for NES Day 16: Finally moved enough functions around so that the famitone2 and example sfx fit in the fixed bank. Turns out the sound doesn't actually work? Sigh. #downland #tandy #coco #nintendo #nes

Downland for NES Day 16: Even more moving of functions out of the fixed bank. Can *almost* fit the famitone2 lib and an example sfx in the fixed bank. I've avoided it as much as possible but now I'll need to start cutting up the shared Downland code. Pain. #downland #tandy #coco #nintendo #nes

Downland for NES Day 15, con't: While I figure out the tools, tried integrating a sample sound fx in the game. Of course I'm busting the fixed_bank size and I somehow have to find more than 1k of space. Still moving functions around. It's getting real annoying. #downland #tandy #coco #nintendo #nes

Downland for NES Day 15: Started to look at sound. The sound conversion tools I thought that would convert sounds aren't converting sounds. #downland #tandy #coco #nintendo #nes

Downland for NES Day 14: Restored screen transitions. Code clean up. Moving out lots of data out from the fixed bank but still always hitting the 16k limit as soon as I implement new stuff. So frustrating. Only sound is left now. #downland #tandy #coco #nintendo #nes

Downland for NES Day 13: Fixed the background drawing. Restored part of the titlescreen by moving stuff around in banks. Restored jumping. #downland #tandy #coco #nintendo #nes

Downland for NES Day 11: Some progress. Figured out why the background wasn't being drawn correctly. Trying to move code to different banks. Looking at bugs. #downland #tandy #coco #nintendo #nes

Downland for NES Day 10: No luck figuring out my linker problem tonight. But there is a possibility that I've hit a llvm-mos compilation bug, though! Top men are looking into it. Who? Top men. #downland #tandy #coco #nintendo #nes

Downland for NES Day 9: Not a productive evening. Trying to investigate why uncommenting the setting of a flag somehow balloons the first bank from 13k to past 16k. Linking errors can go jump in a lake. #downland #tandy #coco #nintendo #nes

Downland for NES Day 8: Exporting banked resources. Brought in and now running the game main code. Drawing sprites. Might have a slight issue with backgrounds. Can't currently jump because enabling the flag somehow causes a linker error. #downland #tandy #coco #nintendo #nes

Downland for NES Day 7: Not a lot of time on it today but got banking figured out. It's so simple compared to the Master System it's almost silly. #downland #tandy #coco #nintendo #nes

Downland for NES Day 6: Worked on the exporter. Did a clean up pass and now exporting tilemaps. Lots of fiddling with the makefile to get everything to build. Gotta figure out how banking works now. #downland #tandy #coco #nintendo #nes

Downland for NES Day 5: Can now display a map. Done experimenting, started the nes project proper. Trying to get it to compile with the game code. Have to work on the DLExporter too. #downland #tandy #coco #nintendo #nes

Downland for NES Day 4: Now exporting all the sprite tiles. Fixed an export bug. The high bytes weren't exported correctly. Figured out how to draw 8x16 tiles. It's a start. #downland #tandy #coco #nintendo #nes

Downland for ColecoVision Day 2: Sound works better if I use the actual correct PSGLib file. Whoops! (whoopsie!) Updated a few minor things. And I do believe it's pretty much done! The updates to DevkitSMS make this port super easy #downland #tandy #coco #coleco #colecovision #devkitsms
