SMSRally, Day 18. Smspower folks suggested a "double buffered" car tile update solution. Copy the car's tiles over 2 frames into a "back buffer" area while using an "active" tile area for the current sprite. Switch when the copy is done. #sega #mastersystem #homebrew #devkitsms

SMSRally, Day 17. Worked on improving the world to pixel to screen space transformations. The car follows the ground better now. Sprite still glitchy at certain angles. #sega #mastersystem #homebrew #devkitsms #gslib

Downland for Game Gear Day 2: changed the timer and lives markers to be sprites. The lives display has been simplified to reduce flicker. Gotta fix bugs with scrolling when changing screens. Also, this game can be brutal. #downland #tandy #coco #sega #gamegear #devkitsms

Downland for Game Gear Day 1 con't: Added basic scrolling. Tiny screen is still tiny. Lives, time, and score can't clearly be seen. I will remove the top and bottom except the time, and display that with sprites in a corner. #downland #tandy #coco #sega #gamegear #devkitsms

Ugh, fine. Might as well... Downland for Game Gear Day 1: Made a common game code folder for 8bit machines. Migrated SG-1000 and SMS to it. Created GG project. Updated makefile and game colors. The screen is tiny! #downland #tandy #coco #sega #gamegear #devkitsms

Downland for SG-1000 Day 8&9: Finally got sprite drawing working. Reworked the obj gfx, toned down the player to be more like the original. Making 1bpp graphics is hard. I think I'm almost done with this version. #downland #tandy #coco #sega #sg1000 #devkitsms

Downland for SG-1000 Day 5: Still working on the new player sprite. I realized that the black areas from yesterday's version are transparent. Reworked to have less transparency and I think it has a bit more personality now. #downland #tandy #coco #sega #sg1000 #devkitsms

Downland for SG-1000 Day 4: Reworking the object graphics for 1bpp sprites. I can't use the original 1bpp ones because they're made in such a way that they assume CRT artifact effects to produce colors. #downland #tandy #coco #sega #sg1000 #devkitsms

Downland for SG-1000 Day 1: Might as well try it. Couldn't sleep last night thinking about it. This will probably be more experimental, but let's see how far I can get. Got a basic project building. Anybody got hardware to test on? #downland #tandy #coco #sega #sg1000 #devkitsms

Downland for SMS Day 26: At first I was thinking of converting SFX sample wav files to PSG compatible values, but I've decided to go straight to the source and mimic the CoCo directly. Time to RevEng the sound playback. #downland #tandy #coco #sega #mastersystem #sms #devkitsms

Downland for SMS Day 25: Reading up on the SMS sound hardware and looking up stuff. Still trying to find a strategy to play the Downland sounds with reasonable fidelity/believability. This is not my fun part. #downland #tandy #coco #sega #mastersystem #sms #devkitsms

Downland for SMS Day 24 con't: moved stuff around in the banks and now the rom is half the size, 256k to 128k. I don't think I can get it any smaller because of the uncompressed 6k bitmaps needed for terrain collisions. #downland #tandy #coco #sega #mastersystem #sms #devkitsms

Downland SMS Day 24: Switched to using 8x16 sprites. Sprite tiles take up the whole space now because of the necessary padding. Performance is now pretty darn good. CPU usage spikes to update the score but I don't care. #downland #tandy #coco #sega #mastersystem #sms #devkitsms

Downland for SMS Day 23: Good work day. Optimized a bunch, now alternating collisions every frame, sped up timer handling, smoothed out drop management. Emu says I'm using ~80% CPU in the worst case scene. Solid 60fps #downland #tandy #coco #sega #mastersystem #sms #devkitsms

Downland for SMS Day 22: Just small speedups tonight, related to door drawing and copying sprites. SDCC is very annoyingly unpredictable. Using the techniques I've used so far would tank performance by absurd amounts. WTF #downland #tandy #coco #sega #mastersystem #sms #devkitsms

Downland for SMS Day 21: More optimization. First time hitting 60fps (with some stuff disabled), which is encouraging. No real strategy, though. Just looking at slow functions, randomly changing stuff, and reprofiling #downland #tandy #coco #sega #mastersystem #sms #devkitsms

Downland for SMS Day 20: Continuing to prune out unused vars, de-struct-ifying things, and const'ing the un-const'd. Banks 0&1 down to 15k. Ram usage is 1274 bytes. Also finally tested and works on hardware. #downland #tandy #coco #sega #mastersystem #sms #devkitsms

Downland for SMS Day 18: Optimization time. Found little speed-ups but nothing super so far. I can't tell yet how to craft functions for best perf with SDCC. Straightforward functions appear heavy in Emulicious' profiler #downland #tandy #coco #sega #mastersystem #sms #devkitsms
