Understanding Generation 1 cartridge codes

Hello all,
after reading the documentation here:
https://glitchcity.info/wiki/List_of_revision_differences_in_the_core_Pok%C3%A9mon_games

It says Pokemon Blue had a version "1M". I've never seen any other Gameboy cartridge have a single digit code. and the M would imply Pokemon Blue had 3 version not 2; version 1, 2 and version 13?

I cannot find anywhere else on the web that talks about this mysterious 1M cartridge. I was hoping someone might be able to shed some more light onto it.

Thanks so much!

Hi! The table describes the imprint. Some aren't necessarily different in terms of the ROM/code (there are more imprints than those with a different ROM).

However, it's interesting there is a 1M imprint, and I wonder if it is different like you said.

The original source of that table was from 伝説の and was about the Japanese versions of Red/Green (not Blue). Unfortunately I can no longer locate the exact link, but a Japanese wiki mirrored it. In Red/Green, there was a v1.0 and a v1.1 in terms of ROM differences, as for there being four Japanese Yellow versions (v1.0, v1.1, v1.2, v1.3) (with the differences being described on that page).
