Well I installed the mamewah program a little bit of problem but it seems to work. Now i have the mamewah setup screen also i install the emulator i want and the rom path and it comes up on the mamewah screen the FCEUltra for nes roms works but the game screen never takes up the whole screen it stays as a small window how do i change that. Also when i use the second emulator which is kega Fusion for the sega genesis setting are the same as the nes emulator it never runs it freezes the mamewah screen and locks up and i have to end the program with a ctrl alt del can you tell me what i m doing wrong there?
