Sega Dreamcast developer on a quest to correct the timeline of video gaming history. Working on the modern, open-source indie DC SDK and library OS, KallistiOS.
Interesting pixel art for an upcoming Dreamcast game... seems oddly familiar...
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.

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!

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.

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!

Writing hand-optimized implementations of the C standard library's 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!

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? :)

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!
