Failed to save state (NOT a permissions problem)

Using 1.3.4, specifically the 6/4/2016 win 64 nightly, I cannot save state in one of my save games. I’m using DeSmuME. This is not only particular to this core/game, but to savegame. I’m wondering if there’s some max size of state files that’s possibly configurable? If I archive my savegame and start a new game, I can save states. I can save states from other games in the same emulator, and obviously from other emulators. Are there any limits to state size?

No ideas on this issue?

No limits AFAIK. Dunno why this would be happening. A log may or may not tell us more.
