Yes, Here is the OT and ID I want for Mew
Its the only compatible event for RG Japan Editions
Also the Mew ID from 0000 to 65535 list of OT isn't recognized as Legal in Katakana
I tried to make a savefile for Pokemon Stadium Japanese versions for fun and also I think PkHEX
Surpringsily Mew PK1 Japanese files are legal in International SAV versions , but not in Japanese Saves
I think they need a little fix for Legal Mew OT and ID recognitions
tl;dr: Japanese Mew ID had a legality problem in their Japanese Save versions as here in Mexico said: "Candle in Street, Shadow in House"
Edit: I uploaded this PK1 archives for future legality references
