GameBoy Condition Notes

The clear plastic window over the screen yellows with UV exposure the same way GBA shells do, but that's cosmetic — the condition issue collectors actually watch for is 'screen rot,' a dark stain spreading under the LCD's polarizer layer that's specific to the original GB/GBC display technology and meaningfully devalues an otherwise-clean unit. Always power it on and check the screen edge-to-edge before grading a handheld up.
