SNES RPGs graphical glitches and crashing after few minutes

[ephgames]

Hello, reporting this after testing a few things and looking for input on which direction to keep testing. Earthbound played successfully for about 30 minutes, and then started glitching where the menus stopped working, graphical glitches start and the game crashes. The problem persists on each reboot after a few minutes. Things I've tried include:
Restarted Pocket
Deleted save file and started over
Changed to a different file in case of bad dump
Formatted SD card, re-downloaded SNES core

Any idea what could be causing this? Wondering if it's something with the files or if the Pocket is defective - saw reports of graphical glitches on other cores in this batch of pockets (this is the September 2024 Batch). Tested DKC and SMW and they both worked so far. Thanks!

Update: Confirmed graphical glitches on Chrono Trigger as well. Updated video below
Update 2: Loading Earthbound now breaks to an unplayable state almost immediately as game resets or soft locks. Recorded a spawn loop video in the videos below.

This is very odd. It is likely a FPGA variance problem, though the issue would stem from me not doing something correctly, not something really with the hardware (the question is what?).

You're likely to have the best luck by trying older versions of the core. If it is something I've done, most likely one of those other builds will work fine.
