Taking a break from casting rays. Spent some time getting my old "Mega Driving" examples to compile with #SGDK 2.11.
Also tried to improve my previous attempt at dual pseudo3d chessboards. Still not quite fast enough for real hardware. I have to get better at optimizing.

Fixed some graphical glitches and squeezed a few more LUTs in. I can still add some optimization to the sprite code and delay rendering to maybe make the clears and wall drawing faster in some situations. If that goes well, I'll add some network code for multiplayer DM or CTF #sgdk #segagenesis

Rewrote my #SGDK / #segagenesis raycaster again. This time to get rid of the Toy Story mirroring. The FPS dropped of course. But I think I'd rather run 10 to 13 FPS without mirroring the screen than run 15 to 20 with mirroring.
There's still some optimizing I can do, so maybe 15~ish is possible.

Trying a different approach to rendering textures. #segagenesis

Atari 800XL acting as a stockfish UI with #fujinet through a webserver. I'll have to think a bit on how to make the webserver handle two players. I want to update my Sega retro.link version first.

As it turns out, it's trivially easy to make a #fujinet talk to a Python webserver (with python-chess) in front of Stockfish. No need for me to move my valid-move code to a webserver.
I POST moves and GET the current board. I should be able to make both my A8 and SGDK chess boards talk to this.

Tweaked the column drawing code to make it a bit faster. I might be able to get a few more fps if I tweak the sprites a bit. After that, I'll try to see what I can do with networking and retro.link.
