Trying PS1 widescreen patches.
Alundra - iso patch working (16:10)
Diablo - iso patch working, though this is extra wide screen (32:15)
Vagrant Story - patch (hex code) working, but image is still 4:3, so its squished.
Crash Team Racing - patch works, getting a squished image vertically though. (Seems to affect other Crash games too)
Ghost in the Shell - Game has native Widescreen mode, but image is still 4:3.
I think most widescreen mode/patch requires the emulator/device to output to fill the screen, and the AR/GS codes for widescreen don't work.
You need to apply an ISO patch if there is one.
Too bad I can't use the screenshot plugin to take a SS, as it resizes it to 3:4 (640x480)
@cuevavirus Is there a way to force the image to 16:9 or 4:3?
I will test out more and see what works and what doesn't.
Sorry for the shitty SS, using a phone.
Alundra ISO patched (16:10)
Diablo ISO patched (32:15)
