I've decided to add a new desert theme to my WIP #dreamdisc25 project for the #dreamcast
The actual levels (10) are more or less complete and I can finally focus on polishing and audio.

just for fun, I put together some comparison clips of tile skewing vs scanline subdivision, plus some bonus debug visualization 🧵
you'll have to bear with me tho. bluesky only allows 1 video per post, so there's gonna be a lot. upside: more yapping, more nerd details.

Today's update on the #SonicMania port to the #Sega #Dreamcast... while our leader is fighting the uphill battle to implement the per-pixel/per-scanline visual effects, I've been... errrr... laying the foundation for the goodies we plan for our Visual Memory Unit. 🤣

There's still so much to do for #dreamdisc25, but at least the game loop is almost complete. The visuals also got some love.
And yes, you are a Tomato.
Here are some screenshots (debug cam and gameplay), captured from my #dreamcast

One of the biggest challenges since the Gamescom demo for MD was figuring out animation skinning. Thanks to @kazade.bsky.social 's work on implementing the base framework for gltf anim channel import and @falcogirgis.bsky.social 's sh4zam work, Jeenie can smoothly move!

I'm finally at a stage where I'm no longer experiencing weird crashes. Thanks to my rudimentary VMU logger I was able to identify a bug that only popped up when played from /cd/.
dc-tool-ip (dc-load) and emulators did NOT! trigger it.
Anyway, the focus is on completing the game loop now!

Spent some time getting drifting and handbrake turns working and I'm glad I did, driving around feels so fun now! Just needs some tire smoke 🚕💨
Still need to do some basics like figuring out the scale of my world, but should start making progress now I'm back at my desk.

I've been trying to implement music into my next Dreamcast gamejam project and it was infuriating. For 2 weeks I've been battling against random crashes caused by streaming adpcm encoded files to the AICA. The crashes were all race conds, but not in my code, rather in KOS. Today I changed to CDDA.

One of my favourite articles to work on of the past year was this one that digs into a Dreamcast rabbithole I happily fell into. It also showcases some of Sega's past steps taken for online gaming on console, and a mascot that deserves so much love.

The port of Yume Nikki PS to PC is going pretty well!
It runs at 60 FPS and recently I:
- Implemented Silent Hill fog on PC
- Implemented 100% accurate PS1 dithering
- Implemented a CRT shader (you'll be able to turn it on/off).
