Sonic The Custom Robo

What? I thought the title was clever. Anyway I'm having a small problem with Custom Robo. Even though other ROMs will run at Normal Speeds on my No$GBA, whenever I load Custom Robo it runs at faster then normal speeds. How can slow the game down so it's easier to control?

You want to slow down Sonic? Are you crazy? That's impossible! :) Try change framerate display i.e from 60 to 30 fps. But I can't guarantee that option in nogba

LOL. Robotnik did it once on the Game Gear :P What would be the next step if that option isn't available?
