  • Gryzor (1987)(Ocean): Visual and Sound Issues

Gryzor

Has some color and palette issues on the initial start menu where you can view colors rapidly changing. Also during that screen the sound is static noise. Also in gameplay there is unusual flickering occurring.

This core is nowhere near ready for release, with several of its components needing a large re-write. It is more accuracy issues than not right now.
I will pick up work on this again eventually, but consider it very much alpha for the time being.
