My ED64 died before I could test it out. Seems that the memory chip the game gets flashed to decided to short and burn on me. Thought my PSU on my N64 had died when it was the circuit breaker popping from the short on the cart. I haven't messed with the cart to cause this to happen. DAMNIT!!
The link below describes a cic switching method that seems to be tested. i think for the cic6105 there is a jumper to be closed on the pcb, too. perhaps someone can confirm that. ^^ btw: i wrote that on the first page of this thread 'cause of that link. have a nice weekend, saturnu http://hcs.freeshell.org/ubc.html EDIT: Ok the website is down, right now... as a service i reconstructed the page with google cache: Here's my attempt at a Universal Boot Cartridge for the N64. Laugh as you may, it works. You can insert the cartidge with whatever save you want in the slot and use the switch to choose a boot chip to use. Currently it only supports CIC-6102 and CIC-6103. If you want to do this yourself, you should know that you can connect all of the CICs together, they only need: pin 16 (VCC) 15 (goes to edge connector 18) 14 (goes to edge connector 43) 13 (ground) 11 (1.6 mHz, edge connector 19) 9 (cold reset, edge connector 20) To switch between CICs you only need to deny ground (pin 13) to those that shouldn't be active. If you just switch VCC (pin 16) the "inactive" ones still mess up the operation of the others. I also observed that you can change the CIC at any point during execution of the game, and even reset it, the proper chip is only needed at initial power on (which is why cold reset is suppiled, eh?) though one of the CICs must be connected at all times. All pinouts were figured out by Valery
