Sorry,I don't really understand the technical aspect of ROMs and emulation. But just to be clear ,the ROM's name I'm talking about is "theends" by Stern ,not to be confused with the Konami version entitled "theend". It's a shame that a great game like that doesn't have a proper ROM.. I wish I could help but as a low-tech man I can only play the game not analyse it..lol Cheers mate!
