When trying to load my Pokemon Yellow or Blue save via JoeyJoeBags to an authentic GBC Cart, it shows that there are only Pokemon in Box 1 even though I have multiple Boxes filled with Pokemon through Box 8 when importing them through Pkhex. All the items added and everything show up correctly, but just Box 2 and on don't appear. If I save on Box 2 before exiting PkHex, then load the save back onto the cart, it will show that all of Box 2 is full in game but the rest empty, even Box 1. So depending on the Slot that I save Pkhex on, is the slot that will appear with all the Pokemon in game, but the rest will be completely empty.
This issue was occuring on Pokemon Red until I tried making new save files a couple times and somehow now all 151 Pokemon show up in the boxes but just can't seem to get the same thing working for Yellow or Blue. The problem isn't making any sense to me so I was hoping someone would know a solution or had similar issues before.
Thanks in advance!
