C'est un émulateur différent qui permet de lire la mémoire, sur gambatte ça ne sera pas le cas (ça serait de la triche) mais tu peux check le tid sur les stats d'un pokémon, ça affichera 25794 en bas à droite. Pour les questions en général tu auras des réponses plus rapides sur le discord psr.
Fixed
It is explained in the rejection comment on your submission. It appears that all runs where breaking the alt main rules (in Misty's gym) and the mod team agreed that the runs had to be rejected, even though it is painful to do. They shouldn't have been verified in the first place.
Bizhawk probably wants the gbc_bios (the same you used for gambatte-speedrun). You can put it in the bizhawk/Firmware folder (There is a tas channel on the discord with experienced people in there btw)
