GoKawiilRetro hardware archive details Nintendo 64's Partner-N64 debugging dev kit
A detailed technical breakdown has surfaced describing the PARTNER-N64 PC development kit, built for Nintendo by Kyoto Microcomputer (KMC), which paired with a specially modified N64 console to give developers real-time debugging access. The modified console allowed the debugger software to trigger breakpoints that halted gameplay for memory inspection, and to reset the console via software command, made possible by rerouting IRQ and RESET signals from the cartridge slot to the CPU using added tie-line wires.
