quick update: my DnD is working well with littleFM except for that it occasionally freezes. none of the data gets lost, i just have to restart the system. it does this much more often than it used to though, and im guessing it has to do with littleFM. ill have it freeze on me maybe one out of 10 times im working with it, and theres no particular catalyst that i can figure out. ill let you know if i come up with a more satisfying explanation.
Are you sure this never happens when running LSDj. Does it freeze in the menu or when loading files or doing other operations? Try to see if it has anything to do with light shocks, like putting down the Gameboy on a hard table. (Not violently or anything.)
