Oh, this is just Esppiral loading and rendering a scene from the #PS2 title, "Dragon Quest 8," on a Sega #Dreamcast, no big deal... ...WAIT, WUT?! 🤯 #retrogaming #retrcomputing #gamdedev

"Mute Crimson" from @icedlizardgames.bsky.social, captured from my Sega #Dreamcast! This is an action-packed, precision platformer running at a solid 60FPS, with extremely responsive controls and tight gameplay mechanics. Super polished and fun to play! #gamedev #retrogaming #retrocomputing

Can we get a HELL YEAH for developer, Mephiles, who was just able to host a #Minecraft server on his Sega #Dreamcast (right) and connect to it successfully using a PC client (left)!? #retrogaming #gamedev #retrocomputing

Soon... #dreamcast

Mad modder Esppiral has done it AGAIN by bringing the #Simpsons Hit and Run to the Sega #Dreamcast! ...okay, fine, you got me! This is Homer Simpson in a heavily modded Grand Theft Auto Vice City on the Sega Dreamcast! 😂 Follow him on YT for more: www.youtube.com/@esppiral #gamedev #retrogaming

I'm only happy to do what little I can to spread awareness of the amazing work you guys are doing for the whole #retro #gaming community It's you guys' efforts that push the envelope & help make development more accessible and less intimidating for newcomers too, helping the scene bloom #dreamcast

HUGE day for the Sega #Dreamcast homebrew community! The next release of DreamSDK, our all-inclusive, powerful, user-friendly, bleeding-edge ready-to-go DC development environment for Windows is finally getting a MASSIVE update! #retrogaming #gamedev #indiegame

Just discovered a new way to calculate an approx sqrt of a floating point number 5 cycles faster than using the dedicated instruction on the Sega Dreamcast's SH4, by combining the fast inverse sqrt approximation instruction and a multiplication! #gamedev #retrogaming #retrocomputing #optimization

Epic retro homebrew community cross-over with Elias's beautiful upcoming PS1 game running on the Sega Dreamcast via Paul Cercueil's hotly anticipated "Bloom" emulator!

Jnmartin's Sega #Dreamcast port of #MarioKart 64 is now available! Here's 6+ minutes of footage captured directly from an actual DC console to celebrate! It was an absolute honor to get to be a part of this one! Build Instructions: github.com/jnmartin84/m... #gamedev #indiegame #retrogaming

It's here! Mario Kart 64 for #Sega #Dreamcast Brought to you my the 2 mad geniuses, "JNMartin" & @falcogirgis.bsky.social who has meticulously ported the whole game to run natively on DC all made possible by the recent decomp from just a couple of months back #retro #gaming #romhack #homebrew #n64

Esppiral has just released V.03 of his epic texture and model MOD for our Sega #Dreamcast port of Grand Theft Auto 3! Just look at Claude's jacket and that Xbox-level of detail on the foliage! You can find it here: gamebanana.com/mods/589485 #gta #retrogaming #gamedev

Grabbed some final moneyshots for the repo of our Mario Kart 64 port to the Sega #Dreamcast. Fixing the build system for Windows DreamSDK users before posting an alpha release trailer! Linux and Mac users, you can already build your images here: github.com/jnmartin84/m... #gamedev #retrogaming

I DON'T BELIEVE IT. While I've been working on fixing up the last couple bugs in our #Dreamcast port of Mario Kart 64, jnmartin went and got STAR FOX 64 running on the DC in just two freaking days!? Glitches aside, it's already running well too!? INCREDIBLE. #retrogaming #starfox #n64 #gamedev

Our community mad modding scientist, Esppiral, has returned from a brief hiatus to Grand Theft Auto 3 for the Sega #Dreamcast... and he has brought Claude's enhanced model from the Xbox version with him! 🔥 #gta #retrogaming #gamedev

Just fixing up the last few minor graphical glitches (such as this one) with jnmartin before we're ready for the initial release of Mario Kart 64 for the Sega #Dreamcast! #indiegame #mariokart #retrogaming

Accidentally screwed up the item box diamond thingies in Mario Kart 64 for the Sega Dreamcast... so now I'm writing unit tests for all of my inline SH4 ASM routines that were added during my optimization passes to validate each one in CI on my physical DC HW! #cplusplus #indiegame #retrocomputing

After another week of intense bugfixing and performance gainz, jnmartin is preparing for the initial public release of #MarioKart 64 for the Sega #Dreamcast! Here's your very first look at the state of the game now with fully implemented audio, directly captured from my DC! #retrogaming #gamedev

One of my favorite parts of bringing classics like Mario Kart 64 to the Sega #Dreamcast is getting to add all of the DC-specific polish such as VMU support to make the game feel at home on the platform... Jnmartin has ALWAYS gone that extra mile, and it shows! #mariokart #retrogaming #gamedev

FINALLY got Mario Kart 64 for the Sega #Dreamcast compiling with LTO enabled... which, due to UB in the decomp code, has now broken the game in new and exciting ways! ...maaaaaybe commenting out "generate_collision_grid()" to avoid crashing was a bad idea! #gamedev #retrogaming #mariokart

When you have a sudden epiphany about pipelining single vector-by-matrix transforms for the Sega Dreamcast's SH4 CPU at 3AM and have to grab a notebook... #retrocomputing #dreamcast #optimization #gamedev

Absolutely MASSIVE audio performance gainz in Mario Kart 64 for the Sega Dreamcast from swapping to FP math, instruction pipelining, loop unrolling, prefetching, inline ASM, and the god SIMD instruction on the SH4, FTRV, for matrix transforms! #gamedev #retrogaming #mariokart #cplusplus

Dat look on Mario's face when he sees that he's been ported to the Sega Dreamcast...

So cool of Nintendo to do this in celebration of the upcoming Dreamcast release of the game. 😂

Loop unrolling, prefetching, memory barriers, SIMD acceleration, and custom memcpy() to optimize the SW audio synthesizer and mixer from Mario Kart 64 to not run like crap on the Sega #Dreamcast's 200Mhz SH4 CPU! Here's the first HW capture with audio! #gamedev #indiegame #retrocomputing #mariokart

What would Super Mario 64 look like were it enhanced for the Sega #Dreamcast? Mad DC scientist, Esppiral, is embarking on an epic quest to answer this question! Here's the very first look at his upcoming mod for our Mario 64 DC port! #mario64 #gamedev #retrogaming

Stay tuned for further updates and the inevitable rerelease! #mario #dreamcast #retrogaming #n64 #gamedev

Been writing SH4 assembly code for the Sega Dreamcast all night, trying to create an optimal replacement for the our built-in memcpy() routine, which is slow AF. Any gainz made here will be universally beneficial for every homebrew app or game! #retrocomputing #retrogaming #gamedev #cplusplus

Sega really does what Nintendon't and now Dreamcast is getting a port of Mario Kart from N64 and the decomp code base! It's day zero stuff but... Sega wins again! Thanks to @falcogirgis.bsky.social for the help on this one! youtu.be/KgjskVfAMvc

Draw a cube, convert the cube to vertex data, get all fucked up with projection matrices for an hour, read docs, find that KOS will do the hard part, and finally have a 30 second demo to show for your 4.5 hours of effort. ...still better than my last desk job. ☺️ #dreamcast #gamedev #indiedev

If you aren't already following along with the development of dRxLaX, you should check it out! It's one of the hottest, most highly anticipated upcoming original homebrew titles for the Sega Dreamcast!
