I started playing Pokemon Red and Blue back when the games first released and
both copies have had their save files wiped, their carts sold, and their carts
repurchased more times than I can count. This is the current status
of my current copy of Pokemon Blue.
This section includes: Physical English Blue,
Physical Japanese Blue, and Digital 3DS Blue.
