I thought i might make this video public, now that there is a very stable version for NTSC - J SM64. Might be ported to other games soon.

This code was designed for speedrunners to be able to train specific strats better. 
This will requires an ED64 or  a gameshark.
This code will not work properly on emulator! You'll need the 4MB ram extension on your N64.
It can be easily ported to any other N64 game that uses 4MB ram i guess.

V3:

V2 saves the whole game, V3 only saves objects and camera statuses.
