Kyoto Microcomputer's Partner-N64 Dev Kit: How Nintendo 64 Games Were Debugged
The Nintendo 64 Partner-N64 Development Kit
This is the PARTNER-N64 PC development kit for the Nintendo 64, made by Kyoto Microcomputer (KMC). It required a specially modified N64 console with tie-lines re-routing IRQ and RESET signals to the CPU, enabling real-time breakpoints and resets. The kit also supported the failed 64DD development system, using an IPL ROM PAK for FONT and WAV data. A DCC adapter board allowed parallel cartridge connections for testing. Includes an in-depth video demo.
The Partner-N64 loads the IPL4ROM first, and then loads the game ROM under test, into the cartridge SRAM.
