It's strange, because i don't have any of those problems.
Anyway, no, there is no workaround.
The reason you don't have any of those problems is because I cranked up the SD read-ahead buffer from a default of 128KiB to 2048KiB to... partially ...fix stuttering problems in Sega CD games and Scummvm games with big audio files.
Apparently, trading off random access speed for sustained transfer rate on the SD cards makes SoRR twitchy and prone to crashing. Or I may have found an SD-related bug in the firmware. I just re-tested after moving my initscript to change the SD buffer sizes; a savestate that had a 100% chance of crashing SoRR about 1 second into initializing the stage now causes no problems at all.
Think there's any chance of a tool to change SD buffer sizes in the Zero's GUI? Per-OPK settings stored in the metadata and a little bit of code to change the buffer size while loading games?
Some games benefit a lot more from the sustained transfer rate improvement, and some benefit a lot more from the random access speeds. SoRR is the only app that outright crashes if it doesn't have the random-access speed it's looking for, however.
