Pokemon Mini Hardware Reference

The pokemon mini has a 21 bit external address bus, 24 bit internal, with an external clock of 4.00mhz
The Minx processor (Custom Nintendo CPU) consists of a quazi 16bit ALU, 6 16 bit registers, and 12 8 bit registers.
The Minx processor uses 8bit instruction sizes, with immediate values of 8 or 16 bits. There are two special instructions (CE and CF) which alter the function of the next instruction.
The pokemon mini also includes a RTC EEPROM with 8192 bytes of total memory (a header is used to partition the space into 6 distinguishable blocks). Strangely enough, the first 4 bytes of the EEPROM are set to "GBMN", which can only be interpreted as "Gameboy mini". Perhaps this project was dumbed down as more of a marketing ploy rather than an actual game system.

Although the processor has a relatively high clock speed, the cpu itself appears to have an internal divider associated with the frequency, also, the processor does not seem to decern between ram and rom when it comes to speed. This probibly means that the addressing bus runs faster than the CPU itself, even when it is using the multiplexed cart bus! Strange but true.
