The MetascriptDex is a database of the effects of glitch meta-map scripts also known as GameProgressFlags.

There are at least 98*128=12544[1] possible scripts for each version, which amounts to a huge 25088 scripts split between Red/Blue and Yellow if there are no differences between the Red and Blue behavior.

Due to this, it is unlikely all scripts will ever be covered in the future, however some of the 'highlights' may be indicated in the relevant articles below.

The lines in the middle of the Red/Blue and Yellow lists below mark the end of meta-map script addresses accessible with the expanded PC items.

Thanks the Pokémon Red and Pokémon Yellow disassembly projects for originally documenting these.[2][3]

In Red/Blue

In Yellow


  1. This would be 98*256=25088, however an add a instruction in CallFunctionInTable causes values over 127 to loop back to 0.
