So, does anyone know a way to edit the in-menu part of the emulator itself to acknowledge X as the accept and O as the back buttons? Or is it stuck with O as accept and X as the back buttons. And I don't mean in-game, I mean when you go into the emulator and select things within it, can you use the X button for all that instead of the O button, I've tried to find a way to change it but only can find the in-game control configuration menu.

You do that in the recovery menu.

Hold R while you turn your PSP on.

that's for the psp itself, that has nothing to do with the PicoDrive menu.

True, but it will change X to O and vice versa.

I have my PSP set to X in the recovery menu, and the PicoDrive menu still uses the O, it must be a setting in the PicoDrive itself, half of my emulators use the O button while the others use the X, so it must be a setting in the emulators and I'm just trying to find a way to change this setting. I've looked in the config file, I've looking in the menu's configurations area, I've looked in the eboot itself, I can't figure out where the setting would be.

It is mostlikely preset in the eboot meaning you can't change it.

no way of editing the eboot with something like PSPBrew to change it?

No you have to change the source code and compile it.
