Retroarch is suddenly not working (Tiramisu), I get a blank screen for a while and then quite a bit of code comes up which basically tells me that its gone corrupt. Is there a known bug or i've installed something it doesn't agree with?

Do I buy up all the local stock of 2nd hand Wii Us to keep going, what usually breaks on these things? I'm on a clean 32gb with 2TB HDD & 128SD Im trying to use the gamepad as little as possible, using Wii Pro controller to minimise thumbstick use.
