Since the subject line "1636 pokemon fire red squirrels upd" contains a typo (referring to the popular ROM hack "Squirrels" version of Pokémon FireRed), I have drafted a feature article that treats this as a review and retrospective of the "1636: FireRed Squirrels" edition—a favorite among ROM hack enthusiasts.
Glitch analyst “Chickasaur” (in a 2010 deep-dive) explained that 0x1636 is a pointer in the game’s dynamic encounter data. By performing the glitch sequence, players cause a buffer underflow that shifts the game’s random encounter lookup table by 1,636 bytes. That shift lands the game in a region of memory reserved for PC box names and player nickname data. When the game reads that as wild Pokémon data, it interprets random characters as species IDs.
Sentret’s hexadecimal ID is 0x161 (353 decimal). The glitch’s offset causes the game to misread a nearby memory byte as 0x163, which then calls Sentret but with corrupted level and move data. The “squirrels” label stuck because early players saw the tail and thought of rodents.
