Game Boy Advance game gets split-screen multiplayer through new FPGA core
The latest emulation-powered retro-gaming upgrade to cross our paths greatly simplifies an oft-overlooked capability built in to many Game Boy Advance titles. Namely, it adds the ability to play multiplayer titles in split screen on a single display.
This upgrade is the work of Robert Peip, a developer who's spent years working on field-programmable gate arrays (FPGAs). These days, Peip works primarily on the MiSTer FPGA an open source project that recreates classic gaming hardware extremely accurately through emulation "cores" that replicate every single logic gate involved in the schematics of the original system (most of Analogue's high-end retro hardware is similarly powered by FPGA cores). Such cores are currently available for consoles ranging from the Odyssey 2 through the Neo Geo era and more.
Peip's new "special version" of the Game Boy Advance FPGA core works relatively simply, running two GBA cores in a single MiSTer. As Peip explains, "you get 2 raw GBA cores, one connected to SDRAM, one connected to DDR3, communicating directly inside the FPGA. Sound is used from Core 1 only."
