building up a few event sequences now the scripting is mostly working. The textbox uses a lot of CPU so scrolling around at the same time is a problem.

Been working on a concerningly robust scripting system for my Megadrive game. A few flickers here and there I need to iron out. The textbox engine is my beloved pride and joy.

It's totally safe to switch the Megadrive's background plane address mid-frame, testing that out with some hastily scribbled cloud graphics. Combining that with a raster palette swap and some sprite duplication to make a nice water effect. This console is fun to tinker with.

Been bouncing between a few setups, 60hz on an emulator/GameGear, 50hz on a megadrive. Put 50hz/Hardware for some PAL rep. This just reminded me, on Blastem there are a few corrupted sprite tiles, haven't spotted these under any other circumstance.

The console I'm using for testing is uh not happy, cracks and pops coming from my TV speakers and video dropouts.

Today I've been making improvements and fixing palette bugs. Had a problem where an object wouldn't share their slot properly and end up claiming a second, evicting lower priority objects such as this NPC, causing them to draw with the wrong palette data.

rough bossfight flow, this is working pretty close to how I planned it! Player combat needs a lot of work, haven't merged some good changes in yet.

needs a lot of improvements like a working hitbox and some proper patterns, but this guy was fun to work on

I made it into a youtube video, thank you mr PigsyRetro! He's remaking/demaking Symphony of the Night and I leant him some code to handle 3D props. Video series here, my cameo is in the latest one :) > www.youtube.com/playlist?lis... <

Polishing this stage up, using every megadrive trick I know. It's a short little interstitial area where you'll be attacked by birds while travelling. featuring two framebuffer effects at once using a task scheduler and a big wobbly carriage sprite that drops a shadow (and needs a redraw).

game map is like this wrapped inside a cylinder (ref: gundam unicorn, gundam CCA)

030

Space… bruce! @spacebruce.bsky.social · 05/08/2026

Does this layout feel like a good way to represent a map of an o'neill cylinder? The world layout loops on the X axis between 3 zones, so I want to suggest that by repeating a little bit at the the edges

fixed the 32X port, only using it in subtle ways for now like increasing the background framerate on this stage and fixing a few visual whoopsies. Unless life throws another wrench at it, game is coming to both Megadrive and 32X platforms. #gamedev

I had a spare bit (singular) going free in the tilemap layout so decided to use it to mark secret wall chicken spots. Doing a few arithmetic tricks to make sure it's not a speed burden on the scrolling engine which is already kinda slow.

I once fell deeply in love with that one bonus stage from Melfand Stories...

Space… bruce! @spacebruce.bsky.social · 29/07/2026

also here's a stage background i'm working on, the player is going to be in the mid ground on a cart doing something or other, it works by using the 68k's user mode to render then a bunch of small funky shaped DMA writes to copy up to vram, designed so action can still run at 60fps ontop.

been having an absolutely terrible time IRL (jobseeking in this economy!) I'm porting my game off SGDK and onto the 32X (yes really) and making a native PC port alongside the 16-bit version. 3 simultaneous releases! Bit of a technical nightmare as the 32X SUCKS, but should be worth the pain.

here's it drawing... a blob. The CPU is very unhappy about this and it's missing the occasional frame.

I started on a level editor a year or so ago, never finished it, currently reviving it and getting it working properly. One thing I thought was pretty useful is it can parse the target project's source tree to detect object definitions and pull values.

there are some, uh, rendering issues and the font is broken, but I've got my localisation system with working with non-ascii languages.

Space… bruce! @spacebruce.bsky.social · 04/06/2026

Working on locale/language stuff. bit of a WIP as UTF8 strings aren't handled by this font, but it's no problem to redraw all the text fields while the game is running, idk why this isn't more common. (I don't know french beyond baby level, but if anyone does, bonjour!)
