I know the disc is a little funky, but with pirto cartrige it hesitates sometimes, but as you move the disc it makes the letters disappear. Also something wierd you press the number 1 on keypad it cycles through the game list, you cycle through the game list usually down on the disc. And when your in the game you hit reset and it goes to the begining of the game your playing not the games menu? Seems to me a firmware issue maybe. Let me say i know i bought the cartridge as experimental but would really like to get this cart working. Its a beautitful design nice fit green light but it is what it is.. Just hopeing you guys can give me a hand...Thank you 👍
