Sorry I should have been more specific.
There is a trainer that was recently released by
Belokk for Dreamcast games. When the programs starts it gives you the option of four different trainer types. Then you can insert your game. But once the game starts there must be a way to access the trainer in order to make codes, but I don't see you can do so.
I was hoping this trainer was something like the Gameshark Pro's code generator and if it is, I'll be very happy.
BTW, what others way are there that allow you to search a game's memory addresses to make Code Breaker or Gameshark/Action Replay codes?
