You don't need to use the serial port if you make your own library for the MIPS side. Just translate the keyboard buttons to analog positions. The amount of bits you have is a 32-bit unsigned char (0x00 to 0xFF) on each axis which is heaps. You could have probably up to 10 keyboards connected to the PSX because each keyboard is typically 101 keys. 1 key per bit.
