Interesting pixel art for an upcoming Dreamcast game... seems oddly familiar...

black screen is done, coming to Dreamcast + Steam in a month, and I'd really love it if you wishlisted it 🖤✨ store.steampowered.com/app/4063290 #dreamcast #homebrew #gamedev #spacegame #furry

Here's an actual hardware capture of me cruising through Corneria in jnmartin's port of #StarFox64... ON MY SEGA #DREAMCAST! We have another AAA-quality Nintendo 64-to-Sega Dreamcast jnmartin port on our hands here! Stay tuned for the upcoming release! #gamedev #retrogaming #indiegame

In what just may be his most sacrilegious move yet... Esppiral brings us a scene from GOD OF WAR as rendered by the SEGA #DREAMCAST! 🥹 #retrogaming #gamedev #godofwar #graphics

For everyone who is not yet privy to the fact that the Sega #Dreamcast is alive and well, thanks to a thriving homebrew community and continued GCC support, here is my talk from this year's #FOSDEM, featuring several high-profile DC ports! archive.fosdem.org/2025/schedul... #gamedev #retrogaming

All of my new followers who are confused hearing we have C23, C++23, and the bleeding-edge on the Sega #Dreamcast, here’s the FOSDEM 2024 talk in the GCC devroom about our quest to bring modern things to 1999 game console: archive.fosdem.org/2024/schedul... #gamedev #retrocomputing #cplusplus

Reproducing an old Sega trick with my fast math library for the #Dreamcast, which swizzles XYZW coordinates into WXYZ ordering to prevent a pipeline stall waiting for the W coordinate to get transformed, which we need first for perspective division. #retrocomputing #graphics #gamedev #optimization

Time to right some more wrongs in the timeline of gaming history... Today we have an actual hardware capture of Esppiral doing his thing and rendering a scene from #FinalFantasy X... ON A REAL SEGA #DREAMCAST! #retrogaming #gamedev #retrocomputing

Just managed to shave 9 clock cycles off when initializing a 4x4 matrix to identity on the SH4 CPU found on the Sega #Dreamcast, compared to the implementation found within the KallistiOS indie SDK! GAINZ!!! #gamedev #retrocomputing #coding #programmerlife

Dat awkward moment when you need to write some SH4 assembly code to optimize some matrix routines for the Sega #Dreamcast, but all you have with you is a notebook… #retrocomputing #gamedev #coding #developerlife

black screen can be played from start to finish #dreamcast #homebrew #indiedev #pixelart

Writing hand-optimized implementations of the C standard library's <math.h> routines for the Sega #Dreamcast's SH4, because the implementations we get from Newlib are using slow bit arithmetic on a platform with a baller FPU... ain't nobody got time! #gamedev #retrocomputing #cplusplus

I'm developing a Super Mario 64 clone on the Dreamcast using KallistiOS and raylib (gldc). I plan on making it for the #DreamDisc 2025 competition, just a pre alpha. So far, basic controls and camera movement has been figured out. What do ya think? :) #Dreamcast #SEGA #Mario64 #homebrew

"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

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

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
