+
+Novag Supremo
+
+Hardware notes:
+- Hitachi HD63A03YP MCU @ 8MHz (2MHz internal)
+- 32KB ROM(TC57256AD-12), 2KB RAM(TC5516APL)
+- LCD with 4 digits and custom segments, no LCD chip
+- buzzer, 16 LEDs, 8*8 chessboard buttons
+
+Novag Primo is assumed to be on similar hardware
+Supremo also had a "limited edition" rerelease in 1990, plastic is fake-wood
+instead of black, otherwise it's the same game.
+
+TODO:
+- does not work, most likely due to incomplete cpu emulation
+  (extra I/O ports, unemulated timer registers)
