Simultaneous Button Presses?

[PolloLoco]

I have the 6700 Multiple Keypress Program from emulamer.com - and have used it for the last year. You start it, and leave it running in the background while running any applications that would require a simultanious keypress. IE - Pressing the up arrow at the same time as button "a". Or right and left to behave diagonally.

However, it's clumsy - because if the primary application requires a lot of memory, the program gets shut down. For example, certain emulators like Finalburn CE can force the program to close.

Is there a more elegant fix, like a change in registry entries? Or perhaps a rom with an updated firmware?

I'm just curious if anyone's been able to get simultaneous keypresses on their 6700 - without the background program.

Thanks.
