I saw somewhere that the EXT port on the bottom of the SNES (look at yours if you have one) was intended for this SNES CD drive. Does anyone know of any use for it - commercial products, or homemade devices?

I think the reason they stopped Pokemon at 251 is because the game code uses one byte (8 bits of two positions) to hold the Pokemon number, and 2^8 is 256. Therefore, unless they want to rewrite the next Pokemon game from scratch, they have to keep 255 or lessPokemon. (The 0 byte means no Pokemon.)
