SunPlus SPG280

Historia

There is one Chinese company with several names that makes chips that you could probably find in devices you already own: SunPlus. The SPG2xx series use a custom instruction set (“u’nSP”), and are designed for something like the TV Plug-n-Play games; they are used in most (if not all) of those, as well as the Vii and the V.smile (if nothing else). Segher took our dumped ROM and scant documentation and built a disassembler, and then a mostly-working emulator for this architecture (more on this below). The top of the line SPG290 uses a different “s+core” architecture, and is used in the Mattel Hyperscan. Jakks Pacific TV Plug’n’Play games also use SPG chips SPMP The SPMP series chips are ARM-based SoCs that are used in cheap Chinese “Personal Media Players” that also generally come bundled with NES or GameBoy emulators.
