Without continued development though, new games are likely to have an increasing number of issues running on either emulator.
Even Starlink: Battle for Atlas, the closest thing to a Star Fox game on the Switch (can’t just get another version of it, since the Star Fox DLC is Switch-exclusive), crashes in both Yuzu and Ryujinx, something I’d hoped would eventually be fixed before the emulators were taken down.
MKVToolNix Batch Tool should be able to do it automatically, assuming the subtitle format is supported.
