Full-stack developer from Brazil. Building things at Yomali and vibe coding whatever seems cool or useful.

• 🎬 neo-geo-cd-fmv — A custom full-motion video codec and bootable player built specifically for the Neo Geo CD: 320×224 at 15 fps, native 16×16 sprite tiles, graphics RAM as a persistent dictionary, continuous 1× CD streaming, and synchronized YM2610 ADPCM-A audio. Includes the 68000/Z80 source, offline encoder, measured performance data, and complete technical documentation without distributing any media or BIOS files.
• 🎞️ sega-32x-fmv — A bootable Sega CD + 32X Cinepak full-motion video player with asynchronous CD streaming across the Sub-68000, Mega Drive 68000, and both SH-2s. Includes the complete source, custom stream format, performance measurements, and build documentation without distributing any media or platform files.
• 🖼️ image-dup-finder — Cross-platform desktop app for finding exact and visually similar images, comparing quality side by side, and safely moving unwanted copies to a recoverable internal trash. Built with .NET, Avalonia, ImageMagick, and SQLite. Download v1.0.0.
• 🕹️ mame-for-ai — MCP server for driving MAME headlessly, focused on arcade and systems without a stronger agent-drivable route: sessions, frame stepping, registers, breakpoints, watchpoints, and CPU-visible decrypted arcade code.
• 🔬 mesen-for-ai — MCP server that lets AI agents drive Mesen headlessly for SNES, NES, PC Engine, and Game Boy Advance reverse engineering: frame control, registers, memory callbacks, breakpoints, traces, and Code/Data Logger exports.
• 🧬 exodus-for-ais — Linux headless port of Roger Sanders' Exodus Mega Drive emulator with an MCP server, so AI agents can drive Active Disassembly through an API: execution-guided code/data separation, jump-table recovery, breakpoints, watchpoints, and traces. Verified against a Windows MSVC build by a cycle-equivalence gate — byte-identical traces over 18,941 68000 instructions.
• 🛰️ ares-for-ai — Headless fork of the ares emulator with an MCP daemon for AI-driven Sega 32X, Mega CD / Sega CD, and 32X CD reverse engineering: frame stepping, memory, registers, trace, breakpoints, and execution-guided code/data maps.
• 🏞️ pitfall-2600-genesis — A Sega Genesis / Mega Drive port of Activision's Pitfall! (Atari 2600, 1982), reimplemented in C with SGDK from Thomas Jentzsch's commented disassembly — pixel-exact collision and original timings, shipped both as a 1:1 port and as a 16-bit remaster with all-new artwork. Play it on itch.io.
• 👾 hong-kong-97-genesis — A 100% faithful Sega Genesis / Mega Drive port of the infamous SNES Hong Kong 97 (1995) — reverse-engineered from the original ROM with a custom 65816 disassembler and reimplemented in C with SGDK. Play it on itch.io.
• 📨 telegram-mcp-worker — Cloudflare Worker exposing a Model Context Protocol (MCP) endpoint that sends Telegram notifications, so AI assistants can message you. Streamable HTTP transport, gated by a secret path, with all credentials kept as Worker secrets.
• 🕹️ xevious — A faithful Sega Genesis / Mega Drive port of Namco's arcade Xevious (1982), in 68000 assembly, built on jotd666's reverse-engineered core. Play it on itch.io.
• 🎮 shadps4-game-manager — Desktop app that installs PS4 PKG files into the shadPS4 emulator and manages your library of games, updates, and DLCs. Built with Rust and egui.
• 📺 iptv-freedom — Desktop IPTV client for Xtream Codes providers: live TV, movies, series, downloads, and favorites — fast, native, and in 20 languages. Built with Electron, React, and Tailwind CSS.
• 🎙️ streamer-copilot — Desktop copilot for live streamers: unified chat across Twitch, YouTube, Kick, and TikTok, sound/voice commands, scheduled messages, raffles, polls, and customizable OBS overlays. Built with Electron, React, and TypeScript.
• 📜 20th-century-democide — Open-source preservation archive for R.J. Rummel's powerkills democide research corpus, with full provenance metadata and a multilingual static site. Built with Astro.
• 🗺️ latency-map — Desktop app for measuring network latency and traceroute to cloud provider endpoints worldwide. Built with Electron, React, and TypeScript.
• 👀 lurk-buddy — Automatic stream lurking for Twitch, YouTube, and Kick. Never miss a live. Never lift a finger.
• 📦 ps4-pkg-extractor — Simple command-line tool to extract PS4 PKG files. Written in Rust.
