So I got myself an "NEO N64 Myth + NEO2 Pro 1024M SD" and spent 4 hours just to get the menu to boot from my n64. It said "failed to burn N64 menu" or USB desync bla bla". And when I finally got it to work I found out that the only games I get to even boot from my SD card is Goldeneye, Mario 64(jap and EU) and Doom 64 of the games I have. It can't even boot Super Smash Brothers. Some times when I try booting a game it hangs on 100%, the lamp on the flash cart blinks 1 time and in the rare event something actually happens the screen goes black. I also tried burning the roms directly into flash but it always fails on validate or desyncs. I tried 3 different computers too.
The game I'm using to boot with is Goldeneye Europe and I'm using a n64 black edition Europe. Am I doing it wrong?
