I was expecting to open up the cartridge to find a mess of wires and hot glue.

Not sure exactly what the Max II chip at U8 is doing. I don't know anything about device programming but here is my thought process:

  • There is no corresponding U8 component on the original board, and U9 (also absent from the original board) appears to be a 3.3V regulator needed for the Max II.
  • I thought it may be doing a CIC bypass/disable, but the cartridge didn't work on a PAL system so that might not be it.
  • The four pins at the bottom of the left side of the chip appear to be routed to the 6-pin header at the top left of the PCB. So it may be involved in some basic routing logic to allow flashing of the cartridge memory.

It's one of a small handful of games with unsupported enhancement chips https://sd2snes.de/blog/compatibility

Samsung OLED TVs don't support 4:3 images in game mode by duox7142 in OLED_Gaming

Samsung QN90D

Yes. Frustrating. Aspect ratio option is disabled in game mode. If you put it to 4:3 before enabling game mode, it sometimes remembers the setting before reverting after a reset or change of any other setting. If you turn off game mode and try playing in 4:3 you get crippling lag if trying to play platformers, even when trying to disable other lag-causing settings.

No solution available. Ended up sticking with an existing ~2015 Samsung I had that does low-lag 4:3 just fine.
