Some time ago I was focused on developing emulators. At the time, the emulators for the following systems were successfully completed: GameBoy Advance, GameBoy / GameBoy Color and NES / Famicom, Chip8, Master System II / GameGear (proto), SNES / SFC (prototype) whose demonstration videos can be found on the YT channel. Currently my efforts are focused on the following: the creation of Homebrew for various systems, the development of some tools to facilitate the hacking of games, the development of some translations and the creation of several cores for FPGAs in Verilog / VHDL.
