>>> ANTIRUINS 3D Trying some sort of very basic dungeon room. Linear filtering for the textures. No lighting yet. #dreamcast #sega #indie #homebrew

A few glitches here and there but the #dreamcast version is back up and running 😎 #retrogaming #indiedev

Added support for pre-rendered/photo backgrounds to my PS1 game. Looks pretty cool.

One of the most impressive homebrew tech demos I’ve ever seen for the #Sega #Dreamcast! I’m honored and am so proud that it’s using my SH4ZAM linear algebra library to accelerate its math! Way to go, dude! #gamedev #graphics #retrocomputing

Direct hardware capture taken of me testing out matrix and linear algebra optimizations I've introduced into our Legend of #Zelda Ocarina of Time port... RUNNING ON THE SEGA #DREAMCAST!!! #gamedev #retrogaming #n64 #oot

MASSIVE UPDATE ON OUR #SONIC MANIA PORT! Here's a series of hardware captures taken directly from my #Sega #Dreamcast! Thanks to jnmartin and the crew, the 3D stages are all now running fullspeed!!! #gamedev #indiegame #retrogaming

One of the biggest shortcomings of the #Dreamcast imo, was the lack of a second analog stick on its controller. Well, "Nai Adventure" is finally addressing this issue, and then some, with the new "Dream Color Plus" controller A fundraiser campaign is scheduled to open up this weekend #retrogaming

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! #simd #cplusplus #retrogaming #signalprocessing

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! youtu.be/j2JTcDY9LI4 #retrogaming #N64

We just got a cool little preview from @freakdave.bsky.social of the rather impressive FDV Engine for the #dreamcast, showing reflection & refraction effects Boosted with sh4zam‪ improvements by @falcogirgis.bsky.social Video Link: youtube.com/watch?v=XSCVXxCTbCw #homebrew #Retrogaming #gamedev

🚨 NEW DREAMCAST GAME 🚨 Alien Taxi, my entry to Dream Disc '25, is up now! 👽🚕 captkuso.itch.io/alien-taxi #dreamcast #homebrew #gamedev

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! github.com/gyrovorbis/s... #gamedev #retrocomputing

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! #gamedev #retrogaming

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. #dreamcast #gamedev #homebrew youtu.be/QcI3XUieh_Q

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! #homebrew #dreamcast #gamedev

"You are Tomato" is live! freakdave.itch.io/you-are-tomato #dreamcast #dreamdisc25 #gamedev

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! 🍅 #gamedev

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) #gamedev #homebrew youtu.be/IsQLCZNgiPg

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. 1/9

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! #dreamcast

The next #Nintendo64 classic has just hit the Sega #Dreamcast! Here's over a minute of #SuperMario64 gameplay, captured directly from my DC! To convert your N64 ROM into a DC image, follow the link to the web-based builder on the GitHub repo: github.com/jnmartin84/m.... #gamedev #retrogaming

(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)! Download: github.com/DerekPascare... Video tutorial: youtu.be/YZtgtykCnM4

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. #dreamcast #homebrew

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.

I have been trying to implement GJK/EPA collision detection in C for two weeks now. GJK works, but my EPA code is screwing up the polytope faces and I can't see the bug! Code is here if anyone fancies a bug spotting challenge: gitlab.com/Kazade/picop... #gamedev

Jesus CHRIST, he's done it again... Mad Sega #Dreamcast scientist, Esppiral, has taken another step towards correcting the timeline of gaming history by getting #VirtuaFighter 4's "Temple" stage rendering on a stock Dreamcast... this is a direct HW capture! #gamedev #retrogaming #retrocomputing
