(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

At least there's a current gen console that will always get physical releases!

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

Our port of #Sonic Mania to the Sega #Dreamcast is nearing completion! Here's 2 minutes of footage captured directly from my physical DC! Stand by for the Blue Blur's epic return home to a #Sega console! @sonicfreak94.bsky.social #retrogaming #gamedev #gamedevelopment #indiedev

Looks like realtime shadows (Dreamcast, PSP, and desktop) will be landing in Simulant very soon! #gamedev #dreamcast

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

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

Short video with some fixes, also showing the LOD/morphing that allows for relatively large environments to be rendered on #saturn using just a few quads. #retrogaming #indiedev

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!

Direct hardware capture of a scene from #ResidentEvil 4 recreated within the PH3NOM engine, running on an actual #Sega #Dreamcast! This was after only a week's worth of hacking too! Unbelievable! #re4 #gamedev #retrogaming

Got something cool for the #Dreamcast #homebrew community @mousesmistake.bsky.social is working on a new 3D platformer, entitled "Dust Magic" Running on the "Simulant Engine" developed by @kazade.bsky.social and utilizing @falcogirgis.bsky.social's "SH4ZAM" fast math #retrogaming #gamedev #indie

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.

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

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

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

This is what the Dreamcast VMU SDK looked like in 1999 (April 22), with a tool to simulate/emulate it on your development environment

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!

Can you imagine if this and GTA3 were released on DC back in the day? SEGA might still be in the home console market!
