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

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

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). #gamedev #indiedev #yumenikki #psx #ps1

Chunky, but 60 fps 3d possible with colors and transparency on bare metal Megadrive #SGDK #BlastEm

New Yume Nikki PS update looking 🔥 💯 (was inspired by @monoko1011.bsky.social art) #gamedev #ps1 #psx #yumenikki

Hand-optimizing SH4 assembly for jnmartins upcoming port of #StarFox 64 to the Sega #Dreamcast, so dropping bombs doesn’t drop FPS! #gamedev #retrogaming #cplusplus

The last toast by the legend herself: I leave it up to you to go to lindken.com and look up Jennell Jacques, now look at her job description, goddess of technology… and fuck cancer, fuck it in the ass - Becky

I never thought I’d get this wish. Odd seeing eulogies before I expire

Rebecca Heineman @burgerbecky.bsky.social needs to be transfered by helicopter to a medical center where they can better treat her cancer, which means her gofundme needs $20k more. please give to support this trans game dev elder if you can!

Unreal Tournament can now be played IN A BROWSER dos.zone/mp/?lobby=ut Along with other late 90s PC FPS classics but yeah. UT99 in a browser window... just fantastic. Thanks to the r/LGR subreddit for letting me know about it!

Now both Vinny and Joel have streamed my Yume Nikki PS1 reimagining. And they both liked it. I think I made it... 🥹 #yumenikki #psx #ps1 #gamedev

jnmartin has been putting the finishing touches on his #StarFox 64 port to the Sega #Dreamcast! To hype up its upcoming release, here's a direct hardware capture of the intro scene! Notice how crisp and sharp the textures look now? ...can you spot the blasphemous texture swap?🤣 #n64 #retrogaming

Mixing SH4 ASM, C23, and C++23 together within the same hardware accelerated linear algebra library for the Sega Dreamcast (which also runs unit tests on real HW) with the hopes of democratizing the upper performance echelons of what the SH4 FPU is capable of... #gamedev #retrocomputing #cplusplus

Experimental post: Mode 7? What About Modes 1-6? Some games on the SNES, such as Super Mario Kart, boasted "Mode 7" technology. However, this raises the question of what happened to the previous modes. This post explains them and gives examples of their usage in Mario games.

It's time for the second annual DreamDisc #gamejam for the Sega Dreamcast! We have prebuilt frameworks and libs such as #raylib and #sdl for developers of any experience level. Top 10 entries get published to a physical DC disc release! orcface.com/events/02-dr... #gamedev #indiegame #retrogaming

Looks like the page is up for DreamDisc '25! Still not decided if I have the time to enter this year with black screen getting done, but it's a really fun ride if you're curious at all about developing for the Dreamcast. itch.io/jam/dreamdis...

GP Advance was a 3D GBA racing game in development at Italian studio Prograph in 2003. Marketed as having "Psx-level graphics", using an in-house engine, the game featured up to 45k polygons on screen, running smoothly. In the end, no publisher could be found and the game was cancelled.

Yume Nikki PS1. Demo out NOW! It contains two dream worlds to explore. You can run it on a real PlayStation 1. This is a fan game. I put a lot of love and care into it. I hope you enjoy it. #yumenikki #ps1 #psx #gamedev #homebrew

The demo for Yume Nikki PS1 will be released in about 24 hours! I'll see you there. ;) #yumenikki #ps1 #psx #gamedev

I've been on the down low for a bit, but decided to start game dev again for the Sega Dreamcast. I'm currently working on a demo for the RPG Elysian Shadows, starting with pixel artwork. We'll see how it goes. #pixelart #dreamcast #gamedev

Yume Nikki PS1 work. I did so much recently... #yumenikki #psx #gamedev #ps1

Jumping! I want the driving to feel smooth and arcadey like a Sega Rally. I was never a big fan of Wipeout's physics, but I love the graphics obviously :)

Worked on balance a bit today The spread shot upgrade (bottom left) is game breaking as hell, but as it turns out is also super fun to fly around blasting, so screw balance, it's staying. #indiedev #pixelart #dreamcast store.steampowered.com/app/4063290/

I decided to go with launch NTSC packaging for the Founders Edition.
