This is the game's standard internal listing of PSI names. Name entries are 35 bytes long, stored in plain EarthBound text. Each entry includes the full text of the name followed by a space, and is padded with null bytes. Power level symbols (the Greek characters α (alpha), β (beta), γ (gamma), Σ (sigma), and Ω (omega)) are added later.

Regarding the Special PSI

The string table hard-coded in EarthBound shows entry 01 as "PSI ????". However, an ASM routine at 0x01C60F acts as a functional override, which uses the "PSI Favorite Thing" string stored in the game's Save Memory. The value at this location can be changed to override any of the entries in this list. Changing the value to 00 will effectively disable the override.
