It's possible to rewire the CPU and RCP if you decide to cut that low but I would recommend cutting to that first line above the 1997 Nintendo logo silkscreen. That way you'd only need to rewire the RCP
Decided to try my hand at making a custom breakout PCB for the RCP.
I tried to make the footprint based off of the compendium image, but it was super difficult to scale down correctly.
I ended up finding a github with all the N64 footprints (https://github.com/dmkfasi/nus-cpu) in it luckily so...
It's a lot worse than the Wii. You're in about $150 already just getting the console and RAM chips. I had the unfortunate problem having to start a second build which I left the RAM chips on since I am still hoping I can go back and get that one working.
Small update.
I finished off the last part of the trim! I have successfully removed the cartridge slot!
Now I am ready to rewire and put this bad boy in the N64HH case!
What exactly does this do? Thanks for sharing the firmware. I have a board that's flipping the image upside down. Maybe using the firmware to re-flash my board will fix it.
After a couple of weeks putting off the RCP cartridge relocation, I finally got around to giving it a go.
I used the compendium to make sure I got all the wires done correctly. I also followed this guide for where to wire the 3.3v lines...
That's too bad on the chip. Those were not cheap parts. I ended up getting 4 of them after I messed up my first build. I'm still hopeful I can get that first board working again though.
