Standalone port of the Bally Midway MCR arcade families for Sipeed Tang FPGA boards — no MiSTer/HPS required. MCR-2 (Tron, Domino Man, Satan's Hollow, Wacko, Kozmik Kroozr, Two Tigers), MCR-3/91490 (Tapper — hardware-verified — plus Timber and Discs of Tron), and MCR-1 (Kick, Kic
Standalone port of the Bally Midway MCR arcade families for Sipeed Tang FPGA boards — no MiSTer/HPS required. MCR-2 (Tron, Domino Man, Satan's Hollow, Wacko, Kozmik Kroozr, Two Tigers), MCR-3/91490 (Tapper — hardware-verified — plus Timber and Discs of Tron), and MCR-1 (Kick, Kickman, Solar Fox; builds, unverified). The flagship target is the Tang Console 60K: each family's games in one bitstream, selected at runtime from an on-screen menu, ROMs loaded from a single microSD card shared by every family (pack format v2). The roadmap toward the full-series multi-core jukebox is at the top of…
