Core Suddenly Stopped Working Altogether

[TGW3]

I had loaded both the 2600 and 7800 Cores, and for a few days, they worked great. Now, however, without any other updates or changes to either my Pocket or the SD card, they are messed up in a few different ways:

• Neither one will read the full directory of available games, and even add a bunch of weird file named such as "Play all BIOS games" which never existed prior
• The 7800 Core will only load a black screen with a strange clicking sound.
• The 2600 Core vomits up a bunch of audio and visual noise

I have tried uninstalling and reinstalling the cores, but the same results occurred.

did you update firmware on the pocket? I've never gotten it to work on mine so you are doing better than me. What does you directories structure look like and the option?
