Testing fixes for Gamma's screen overlay effects for use with widescreen on Flycast. This was the last technical requirement to get PkR and Exant's Flycast Widescreen patch pretty much done.

The scanlines that scroll needed fixing, the static pixels needed fixing, now everything renders to 16:9 properly and is tested as working without crashes. It is now integrated into the Flycast Widescreen mod and distributed with PkR's DC Image Builder for Sonic Adventure Dreamcast version 1.005.

This will Only work on Flycast and is not hardware compatible. You can use the stretch widescreen mod for hardware instead.

Our DC mods can be found here alongside instructions and links for the DC Image Builder: github.com/X-Hax/dreamcast-mods
