Side quest in texture land... DMA is on it's knee and interrupts are eating a good chunk of CPU on #SegaMegadrive #SGDK #BlastEm

Jumping! I want the driving to feel smooth and arcadey like a Sega Rally. I was never a big fan of Wipeout's physics, but I love the graphics obviously :)

More Mega Driving. Mostly so I can avoid thinking about how inefficient my raycaster sprites are. #sgdk

Basic road clipping and collision is on, the ship is just two triangles but with dynamic(ish) shadow! It runs pretty well, I'm quite happy with my rasterizer so I will try to add more polygons and scenery #SegaMegadrive #SGDK

Only 2 colors, but finally some stable 30fps 3d without line-doubling (256x128 or 320x128 pixels) on stock Sega Megadrive :) The bottleneck is the height of the polygons. I exhausted all my ideas so I don't think I can do faster at this resolution.

Today we reveal a very early prototype of The Lion King for #SEGA #GameGear, dated April 1993. Glitchy, incomplete, and packed with placeholders (plus Lemmings music?!). A fascinating look at this work-in-progress Disney title.

More Megadrive Scaling madness !!
Convert scaler to a line scaler rather than column, allows for per line expansion / contraction eg more like mode 7.
Speed up the code & have about 50% cpu free running the scaling (cpu calculated) + sprites + audio etc.
The target for this is ingame effects !!

most recent build of my #SNES Baseball engine. I've got a few different pitch types in there currently, and they move pretty well

I'm super curious, is the code for this public?

I kid you not, @itch.io has been taken down by Funko of "Funko Pop" because they use some trash "AI Powered" Brand Protection Software called Brand Shield that created some bogus Phishing report to our registrar, iwantmyname, who ignored our response and just disabled the domain

I couldn't figure out a way to generate the sequence though I was close. FM may be easier to recognize though SMPS would have trouble playing it back due to the speed required to stream the audio.

Did get to play around with the format and make some cool transmissions.

Might revisit.
