(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.

DOOM running on cat's PC in my ꩜Dreamcast game (direct HW capture). Recorded this again using RetroTINK 4K Pro so that it's easier to see what's going on. Been kind of in a state of "where do you go from there..." for the past few days, still can't believe it worked.😂

Dreamcast is so powerful... It's not just an image on the screen. You can interact with the in-game PC with the Dreamcast mouse and keyboard. (I won't copy Win95 for the final look, want to design my own fake OS :D)

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

I've been working on this for over a year: I'm remaking all of Ocarina of Time's prerenders in 3D, trying to match the N64 style rather than the 3DS one. The provisional name is OoT unJPEG. It will be distributed as both a romhack that runs on real N64 hardware and a mod for Zelda 64 Recompiled.

Big ol' GAINZ on the FPU in the #Sega #Dreamcast when applying a translation matrix, after increasing superscalar dual dispatch rate of the processor by finding a novel way to zero out two FP registers in parallel, using two different but parallel-issued instructions. #retrocomputing #simd #gamedev

Small quick stop on #dreamcast. Bumped the texture resolution from 32x32 to 128x128. It looks really nice even on my lame composite capture card, and the game still holds up at 60 fps (640x480) Next back to #ngage to close the circle #retrogaming #indiedev

Fuck off. If anything is "millennial", it's those cool transparent colors our iMacs, Gameboys, and Tamagotchis came in. No fucking millennial likes the house flipper grey. Call it a millennial paint job when I can see through the exterior of a car because it's Glacier Purple like my GBA.
An image showing the colorful transparent plastic of various pieces of technology of the 90's and early 2000s, that were easily the popular choice of the millennial age bracket. Some of the tech is an iMac, Nintendo 64, Sega DreMcast, a PlayStation 2, a Gameboy color and Advance, and CD player.

Small update on the Megadrive *rally game* ? I added sprites and did some optimization so CPU is still at 70% usage with a stable 60 fps. I'm a bit disappointed by the sprite width limit per-line. I wanted a lot more dense vegetation but it's not possible with sprites. I'll try other methods.
