MissingNo.? Should I?

[Alpha Six]

iirc M' is the only harmful one. Missingno does still mess around with your HoF data, but shouldn't do much else.

This is a really good place to go for missingno information.

basically every pokemon search is still incomglitch is covered, with a comprehensive missingno section which after YEARS of reasearch is still incomplete.
They're going for every possible variable to get as much data as they can.

also what was your trainer's name?

Hmm

This site is actually pretty interesting.
