I made a table for Cheat Engine that has some custom code in it to automatically put the n64 ram address in the description of the cheat. you can also put a n64 ram address into the address slot and it will convert that to the right address for the emulator.
just make sure when putting a address into the address slot you don't put "0x" at the beginning or else it wont recognize it.
this one is set up to work with Project64 but it can be changed to work with any emulator. just go to 'Table>Show Cheat Table Lua Script', and replace "2E50FFFE" on line 1 with the memory offset for that emulator
