I've been working on various original projects for the Dreamcast these past few month. With that came the idea of a studio logo, and basically an intro for my upcoming Dreamcast games ☕ yes, this runs on Dreamcast and yes, those sounds are my actual coffee cups lol Wanna know more? check below ↓

(1/3) People have been asking me about this redesigned GDEMU clone (Dreamcast ODE). So I bit the bullet, bought one, and tested it. Firstly, all of the "faster speeds" stuff is pure marketing bullshit. Timing is handled by GDEMU firmware, and it's delicate. You don't want to arbitrarily increase.

Presenting shz_xmtrx_blend(): a new SH4 assembly routine for my fast math library targeting the Sega #Dreamcast! It allows you to multiply and accumulate weighted joint matrices into a single skin matrix, maintained within the 4x4 FP register back-bank for maximum GAINZ! #gamedev #simd #cpp

jnmartin and I are revisiting our port of #MarioKart 64 to the Sega #Dreamcast and are prepping for a rerelease. He's offloaded all audio processing to our SPU and redone the renderer, while I've gone and optimized all of the math and vector routines for BIG FPS GAINZ! #retrogaming #n64 #gamedev

Some time, a decent budget and let's face it: just really clever developers. It also comes down to game atmosphere, optimization at asset creation time, hiding the rougher areas and really good internal studio planning. Whatever they did, they knew what they were doing

Mouse's Mistake (Niels Van Son) @mousesmistake.bsky.social · 06/06/2026

The CPU is the real bottleneck there. Sending commands to the GPU has to happen as unfrequently as possible, and while I try cutting corners obviously I have to find other ways to get around having 1/4th of the New 3ds clock speeds

Mouse's Mistake (Niels Van Son) @mousesmistake.bsky.social · 06/06/2026

No problem, I wasnt trying to blame you 😁 just letting know. Indeed it already runs on O3ds, right now between 15-20 fps. I do think it could be optimized enough to run at full speed, but stereoscopic 3D on O3ds might be complicated. I'll see what I can do!

I think "JnMartin" is just showing off at this point xD Not only has he done a full #decompilation of #Sonic R, to work on a #Saturn to #Dreamcast conversion, But apparently, he has also been busy with porting the game to the New #3DS And it's running so well already! #retrogaming #decomp #recomp

I'm writing that 3ds port from jnmartin's decomp code (that's me playing lol). If you have any questions, feel free. Few notes: - 3D Support is present, though runs slow - This is the full 44.1Khz OST - This is true 400x240 widescreen - Citro3D, no OpenGL wrapping going on - O3DS is currently slow

Wow, I didn't expect to win the🥇place but here we are! It's been a blast developing my little game "You Are Tomato" even though there were times where I thought about just giving up due to random lock-ups and crashes. I'm glad I didn't! Also, congrats to all remaining participants! #dreamcast

I've just released a threaded software implementation of the #Dreamcast "PVR2" graphics chip as a portable standalone library (CC0) gitlab.com/Kazade/libpvr/ I've already plugged it into the "Nitrocast" emulator (lxdream fork) and performance and accuracy are way above the previous implementation!

I guess it depends on whether you see it as a means to an end or something you actually like doing. I can't see myself writing code for the sake of just getting something to work, there's a form or significance in building something over time that looks the way you want it to

I'll never understand why people (including many engineers) can't see programming as the creative art that it is. LLMs generate code the same way they generate images or videos. Bland, mediocre, inelegant remixes of the training data.

Frankly the more you indulge in game dev, the more you start to feel bad for developers of half-baked AAA games instead of feeling like it's their obligation to provide, it really is just one big bug hunt that takes much longer than anyone likes to admit

Having built many many kinds of software products, I can't tell you that the hardest final 20% goes to games over all else. That first 80% is way more fun, but that final 20 is soul destroying. It's essentially just looking at bugs going "ah, shit." #gamedev

The DC scene has a pretty strong persence at Gamescom. There's no way they're not at least somewhat paying attention. Met someone from SoA, the both of us sitting right next to homebrew games running 🤣. It wasn't the focus, but he sounded totally on board with retro stuff
