Hacking Question about ps1 emu.self/netemu.self

[jy253]

The game is "ready 2 rumble" and it gives a black screen when running on default emu.self (webman). The fix is to run netemu.self (holding R2 when opening). I prefer emu.self since most games gives a lag when using netemu.self.

Is there a simple patch to apply on the game "ready 2 rumble" so it can run just fine on emu.self. Or I have to manually run it on netemu.self everytime?
