So mayyybe it's possible to render in 4 colors, it takes 20% more cpu but two palettes of 16 colors are then free for sprites and background #SGDK #SegaMegadrive

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.

Improved this more, there were a few single frame hitches that I've squashed out

The first page spread of the manual is shown. You see the Giants Software logo and copyright on the left, and on the right it has detailed instructions for cartridge insertion and making sure you have the console off when you put it in, and have your cables connected, and all that kind of stuff. Feels very much what they would have said if it came out in the 90s.

The project came about because one of the devs was messing with @stephane-d.bsky.social's SGDK and they decided to give them space to make it. Though it was announced April 1, it's a proper game and comes with a downloadable emulator executable! I appreciate how seriously the manual treats the game.

GGS Studio Creation and Broke Studios launched a franchise with The Cursed Knight, a wonderful mix of genres that delivers a solid dose of old school gaming. It has charm, great presentation, and that wonderfully frustrating gameplay we all love.

One of the many reasons #SGDK is such a valuable Genesis game dev tool is its automation of creating multi-sprite objects for characters. I recently got a new version of Blastem that lets me see exactly how sprites are structured and it's very interesting 🀯

Now that the Square Brothers Megadrive port is finished and tested, we started a new game!

We wanted to try something with constant palette swapping to try that engine module!

Unbelievably, 35 years after its US launch, there are enough new games coming for the Sega Genesis that it can be hard to keep track.

Now, you don't have to! I've launched the Mega Drive Tracker, a site that catalogs all the new physical releases coming to Sega's 16-bit console.

I heard rumors of a service called X-Mail coming soon, I wonder if this is it?

My hobby is making a new Sega Genesis aka Mega Drive game.

Today I designed and implemented a turret enemy. Here is my plan for the trigger boxes. I had to make them a little larger to get it t working just right.
