I just released new patched GBSC-Pro AV firmware based on original GBSC-Pro 1.3 release.

We now have full Atari output image without any cropping.

What to do…

1. Update your GBSC-Pro main unit with the original firmware: https://github.com/RetroScaler/gbsc-pro/releases/tag/1.3

2.Update your GBSC-Pro AV unit with my patched firmware: https://github.com/matosimi/gbsc-pro/releases/tag/v1.3_patch01

3. Connect your Atari XL/XE machine with S-Video to GBSC-Pro and enjoy!
