How do you change the emulated hight and width in the rom settings back to default? It doesnt allow for letters only numbers to be typed. What is the default setting?
The default is actually autodetected by the plugin, in some cases in may be 320x240 (usual 4:3 NTSC resolution) or it may be the Pal 4:3 standard or a widescreen resolution, etc... The "problem" is that the plugin cannot properly detect the resolution of some games so those end up being modified by hand.
Clearing both boxes will return it to the default autodetect.
