Moreover, I have observed that the name of the game, code, controllers and some other things in the header are not filled. But it's true that it doesn't influence the running of the game.
Incredible to play this game in a Megadrive/Genesis, I love it!
I test with the Mega Everdrive PRO and works perfect. I tried to create a cart for collect this game but not works on my Nomad :/. Use the soniccd123 boards with FRAM
Another thing, the rom has replicated the header two times
