Battle Stadium: Senbatsu Pro Yakyuu

Debug Menu
At the main menu, select and enter the "おやすみ" ("Oyasumi" or "Good night") option. Instead of powering down the console, enter Up, Up, Down, Down, Right, Left, Right, Left, A, B, Start (a slightly modified version of the Konami Code).

Game Genie code re-enables more hidden options in the debug menu as well as simple Debug Mode access cheat. To get to the Debug Menu, just hold A then press Reset. Previously unused options in the Debug Menu now can be used. Need investigate, what exactly they do. Some of them are writing some signatures to the SRAM, some toggles unknown flags, seems unused now. The game is checking if program is in full debug mode or not by checking the SRAM signature. In release version it is "IGS", but for debug version it should be "ALF". This game genie code just fool the debug signature check.
