After a couple of months' break, I regained some motivation and compatibility has greatly improved. Grandia II in particular seems fully playable, with the only visible issue being the battle transition animation (expected as it relies on hardware capabilities that I'm not emulating yet).
Deecy is an open source Dreamcast emulator written in zig by myself.
