False. I'm literally the author of a vector/SIMD accelerated math/linear algebra library for the Sega Dreamcast, which utilizes the shit out of its special FPU instructions. FIPR and FTRV in particular had higher FLOPS than an equivalent Pentium SIMD: github.com/gyrovorbis/s....
Vectorized, HW accelerated #FFT algorithm for my SH4ZAM fast math/linear algebra library targeting the Sega #Dreamcast's SH4 CPU. Screenshot is a single frame capture from my DC visualizing the frequency domain output of a song in real-time!

The #homebrew projects just keep coming today, it would seem.
Apparently, an anonymous developer is currently working on porting #Zelda: Ocarina of Time to the #Dreamcast
And so far, it's looking pretty good.
"thesegaguru" has gotten an exclusive first peek!

We just got a cool little preview from @freakdave.bsky.social of the rather impressive FDV Engine for the #dreamcast, showing reflection & refraction effects

You Are Tomato on SEGA Dreamcast – Cult Indie Chaos | Review & Gameplay
Welcome to a new week - You ARE Tomato! Deal with it!
#YouAreTomato #SegaDreamcast #Dreamcastgames #Dreamcasthomebrew #Freakdave #indieDreamcastgames #retroindiegames
Two builds of #MarioKart 64 running on the #Sega #Dreamcast. Top is release using our stock GLdc driver for graphics. The bottom is an experimental build I have optimized with my accelerated math library, SH4ZAM. Community gainz are coming!

Here's the world's very first look at the #Simpsons: Hit & Run... FOR THE SEGA #DREAMCAST!
Developer, maximqad, has decided to undertake this insane porting endeavor, and while it currently runs like ass and needs extra RAM, that's better than GTA3 DC was at this stage!

Aaaaand it's finished!
Here are all 10 levels in its full glory.
It may not seem like much but trust me I've been through so many issues and crashes that I was *very* close to giving up.
But now it's in a state where I am happy with the results.

Only a couple of small features left to add now (and audio!) but starting to polish things up a little more now for the end of the jam
#dreamcast #homebrew #gamedev
Made it so that each tile in my tileset has a different resistance, so driving through mud or deep water will slow you to a crawl.
Feels a lot more dynamic!

Here is one of the later levels from
"You Are Tomato",
a #dreamcast #homebrew game that I am developing right now for the #dreamdisc25 game jam.
I can't wait to share all 10 levels with you soon! 🍅

It's the first time I am showing "You Are Tomato" in motion.
There's still 1 month to go until #dreamdisc25 's deadline!
Oh yeah, and I've finally switched to sh4zam for a "slight" perf boost on the #dreamcast (thanks! @falcogirgis.bsky.social)

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.
#gamedev #homebrew
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. 🤣
#gamedev #retrogaming #sonic
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!
#SonicMania Plus for the #Sega #Dreamcast finally has audio! Here's a 2 minute direct hardware capture of me playing the latest build of @sonicfreak94.bsky.social's port on my actual DC to hype up the Blue Blur's epic comeback to a Sega console... where he has always belonged!
#retrogaming #gamedev
Exploring @8bitmods.bsky.social latest SDK for their superb #vmupro. Not sure if it can run DOOM but it surely can run DOOM fire :D
Discord wants to know how you feel about AI.
Go tell them: discord.sjc1.qualtrics.com/jfe/form/SV_...
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!

The next #Nintendo64 classic has just hit the Sega #Dreamcast! Here's over a minute of #SuperMario64 gameplay, captured directly from my DC!

(1/2) It's with tremendous pride that I'm releasing my new version of openMenu and the accompany card manager software, bringing virtual folders/subfolders to the GDEMU for the very first time (and more)!

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.

CDDA on the other hand has some weird oddities: Looping is bugged on GDEmu and MODE. The last track won't loop. And on Flycast none of the audio tracks will loop. I assume it's a bug. On hardware it just works (although I have to playback by LBA sectors instead of tracks). I can live with that :-)
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.
