Good jobb! :)

We released our C++ Vulkan graphics demo "Sentinel 7" at #evoke2025 demo competition and we got 4th place 🙂

Recovering from first day of #evoke2025 demoparty :)
In a few hours the Science crew will drive back to Cologne again for some more partying \o/

Finally got myself a #Sega #Dreamcast (and a Naki VGA Box) woot! #segadreamcast
Experience on a 50" Plasma TV via VGA is still amazing in 2024

Kudos to @dark1x and @digitalfoundry for their awesome #idTech videos, which were a great inspiration!

@hfrhjb 😆 just add some glitch overlays/noise, camera shake, and heavy bass audio - done.

[Armin Jahanpanah @arm1n]

PS2SDK on the real thing.
So I have a working dev setup now :)

[Armin Jahanpanah @arm1n]

Yay, #Playstation2 succesfully revived, power supply fixed (replaced capacitor C3) 😄

I used the great guide at

Here is the #ps2sdk VU1 example (built on M1 Mac, running in AetherSX2)

Managed to build #ps2dev cross compiler toolchain and #ps2sdk on M1 Mac :)

Here's the teapot example running in AetherSX2:

There's the measure tool, but that's cumbersome to use to get exact numbers

[Armin Jahanpanah @arm1n]

In #blender #b3d what is the quickest way to determine the world- or local-space dimensions of a mesh object? Can I see the viewport coordinates of my mouse pointer somewhere?

[Armin Jahanpanah @arm1n]

Trying to write a simpler #blender #b3d mesh exporter so far hasn't been a pleasant experience:
- Scarce or outdated documentation
- APIs that seem to change every year or so
- No straight forward way to get triangle index buffer data
- etc.

More RGB30 pixelart shots (some vertical shmup goodness)

[Armin Jahanpanah @arm1n]

Some GameBoy pixel art snapshots from the Powkiddy RGB30 #retrogames

[Armin Jahanpanah @arm1n]

@hfrhjb Pixelart sieht 1A darauf aus. Das heben auch alle Reviews hervor

[Armin Jahanpanah @arm1n]

Awesome little thing.

[Armin Jahanpanah @arm1n]

@hfrhjb Es gibt jede Menge Optionen für Scaling/Filtering (inkl. Integer scaling ohne bilinear). Auch Shader für CRT/scanlines und so. Ist ein Linux mit den bekannten Emulatoren, nettes Dashboard.
Wifi integriert, HDMI out zum TV, Headphones. Auf YT gibts viele Reviews

[Armin Jahanpanah @arm1n]

@hfrhjb Powkiddy RGB30 (720x720px screen mit 1:1 aspect ratio, perfekt für GB und PICO-8) aus China. Emuliert die meisten 8/16/32-Bit Systeme ziemlich gut. Sound und Verarbeitung sind auch prima.
