Dev & Modder. I like taking things apart to see how they work: emulators, game ports, ROM hacking and retro hardware, all on Linux.
I document everything step by step (in Spanish) on my blog: lowlevel1989.click
- dbar4gun: Linux userspace driver that turns Wiimotes + a DolphinBar (or a Wii sensor bar) into light guns. Built for Raspberry Pi / RetroPie, works across MAME versions.
- ambidextro-port: PortMaster port of Ambidextro (Godot) for AArch64 handhelds. Virtual or native controls, a lightweight mode for low-end devices, and mod support through Godot Mod Loader.
- ambidextro-mods: Godot mods for Ambidextro: an in-game achievements screen and snappier trampolines.
- tamatama: runs an Android game
.soon Linux with my own loader (QEMU x86_64 and Raspberry Pi), replacing Android calls with stubs until the whole game runs native. - vol2spinnerd: Rust daemon that turns a USB volume knob into an arcade spinner for Arkanoid in RetroArch.
- Pachinko Wars (SNES ROM hacking): reverse engineering the game's LZSS compression to decompress, edit and reinsert graphics without touching the original code. Write-ups: LZSS graphics · finding the money
- krontra: Contra (NES, Japan) hacking notes: finding lives and weapon values in RAM with FCEUX, then patching the ROM with Radare2.
- PortMaster: I'm a porter: I package and maintain game ports for Linux handhelds.
- RetroPie: dbar4gun install module for RetroPie-Setup, so light guns work out of the box.
- MAME (libretro): fixed the default crosshair path, which matters for light gun setups.
- LinApple (Apple II emulator): disk / HDD eject support, Spanish keyboard layout and build fixes for Fedora / RHEL.
All my merged pull requests in other projects.
- PICO-8 carts on Lexaloffle, like Abacus, an abacus for practicing addition and subtraction.
- RetroAchievements: the retro games I'm playing.
If my tools or write-ups are useful to you, you can support my work on Ko-fi.
