Outside of work I run trespordez.pages.dev — The Archivist's corner for emulation guides, hardware deep-dives and preservation.
I mod, repair and tune classic consoles to work better today — from the Atari era all the way to 6th gen and beyond. GDEmu swaps, region-free patches, recap jobs, RGB mods, ODE installs... if it blinks, I probably wanna poke at it.
MAME · CHD tooling · DOS/retro computing · Cars · Movies & Series
