Okay, so I've mucked around enough and managed to get Mamewah working as it should. I've even managed to get the custom FE all set up.
There are a couple of things I'm trying to get figured out, such as how to disable the 'ok' or l-r joystick nag, but the biggest issue right now is for...
Adding other emulators, such as Z26 & Daphne.
I've successfully managed to add the other items to the "list", but particularly for Z26, I am not able to have it successfully pull up the right layout/screens, even though (and I'm treading lightly on this one) I'm pretty sure I do have the right pathing information in place.
The same goes for launching actual roms; I get a "file not found" dialog, yet again, I'm pretty sure I do have the correct pathing in place.
Any suggestions?
