To jump into the topic:
I’ve set my pi to HDMI group 1 and mode to 4 (720p). I want all my Emulators to stretch the image to 16:9 and have set the configfiles Tod:
Custom_vieport_width = 480
Custom_viewport_height = 640
Aspect Ratio to 1.33 and screen to 16:9 but only some like pocketsnes work and Emulators like picodrive give me fullscreen with master system games but a cropped and smaller image with borders in mega CD games. Where’s the problem? -_-
