So, while "
redream" may seem the most recommended Dreamcast emulator, the fact it holds some features behind a paywall is a bit iffy to me.
But, I found a
list of Dreamcast emulators as well as their ratings, and it seems this "
Flycast" emulator is more recommended by 101 votes over redreams 55 votes. It's got an open-ended emu.cfg so any options that are unavailable, I might be able to put in there (such as my screen ratio).
Other than that, the Flycast site is on github.com than its own site, and it doesn't list all Dreamcast games or rate their compatibility like redream and Dolphin does, so I don't know what fully-runs or not.
But I've downloaded Flycast and will give it a go.I know a rom site (
romsfun.com) that has Blue Stinger and IllBleed so I can check those games off my list.
