this is a tricky situation. i was playing lost in blue (european version), everything was going well and suddenly retroarch crashes when going into the cave. it will not save anymore either, it is just stuck, so i can not provide a save file. the only thing i can provide is a savestate and the segfault from my syslog. this is on arch linux and using the pre-packaged libretro-desmume core.
load the state and just go into the cave, which will crash retroarch. you could also try to save, which will basically end in a stuck game (press start -> quick save). the expected error is that this does not crash the entire emulator.

ELF object binary architecture: AMD x86-64
this is a tricky situation. i was playing lost in blue (european version), everything was going well and suddenly retroarch crashes when going into the cave. it will not save anymore either, it is just stuck, so i can not provide a save file. the only thing i can provide is a savestate and the segfault from my syslog. this is on arch linux and using the pre-packaged libretro-desmume core.
Lost in Blue (Europe) (En,Fr,De,Es,It).state.gz (gzipped due to github not liking arbitrary binary files)
load the state and just go into the cave, which will crash retroarch. you could also try to save, which will basically end in a stuck game (press start -> quick save). the expected error is that this does not crash the entire emulator.
