Pokemon Mini Hardware Overview

Pokemon mini handheld device

The Pokemon Mini is a hand held created by Nintendo R&D3 around 1999. The hardware as engineered entirely in-house and does not appear to contain any off the shelf parts other than a few slightly less important crucial elements like the LCD controller and internal EEPROM. The system is built around a 4mhz custom CPU (with a 4 cycle data access period), with a 4k bios image, 4k of ram and a 21-bit cartridge bus. The internal memory map is decoded as 24-bit with no known mirrors. The entire system is controlled by writting to 256 hardware registers, most of which are Open-Bus.
