![]() ![]() ![]() ![]() The motherboard could still be trimmed smaller however it would require rewiring many more sub-circuits and no space is gained as the limiting factor here is the cartridge and the 3.5″ screen. Then I desoldered the RAM expansion slot and resoldered it at 90 degrees to make it as thin as possible. I trimmed off the cartridge connector and rewired the signals back to the RCP/CPU. I cut it even smaller as close as possible to the required components. The trim I used is based on the Advanced N64 trim from the new Advanced N64 Trimming guide on Bitbuilt. I’m proud to finally hold the record after all these years! Each new record pushed the N64 motherboard to its limit of trimming advancements and case layout imagination. The record to build the world’s smallest N64 portable gripped my imagination since I was a young teenager just getting into portablizing. Get yourself a reliable memory pak that will keep its saves for generations! Author Gunnar Turnquist Posted on JanuFebru6 Comments on N64 Memory Pak from scratch World’s Smallest N64 Portable I think this has turned out to be a good product that is needed in the market flooded with over priced FRAM modded paks so I will be selling them on ebay. Some aftermarket paks that advertise extra memory, quite literally have two memory ICs inside with a switch to activate either chip. Due to the memory bank size, it is not possible to use a larger memory. The memory size is 256KB, which is the same size as the original pak. I modeled the memory pak shell to be 3D printed. The pcb will even fit perfectly in an original nintendo memory pak shell in that case that you want to swap them. I used an FM28V020 FRAM IC which does not require a battery to retain the saves and according to the datasheet it will last 150 years! Most FRAM modded paks I see use parts harvested from an original nintendo memory pak so instead I designed my own pcb so I can build the whole device with off-shelf purchased parts. Ever had your N64 memory pak battery die and lose all your precious saves from your childhood games? Or purchase an aftermarket pak only for it to arrive broken? I have, which is why I designed my own N64 memory pak. ![]()
