This has been released for about a week and a half already, but I haven't seen it mentioned yet. v0.9.10 changelog: Download I've downloaded it and turned on the dynamic recompiler, and wow! If you were used to playing grindy RPGs while holding the speed up key to blow through battles faster, you'll be amazed at how much faster it is now. Edit: After a little bit of tinkering around, it seems the new version of DeSmuME has a tendency to delete save files; make sure to backup your save files before trying it out. A way to load your save files properly is to rename it as a different .sav, then manually import backup memory from the DeSmuME File --> menu.
