Pokemon Crystal Gsm How Do You Transfer Pokemon (Crystal) Save File From Comp To Actual Cartridge?

How do you transfer pokemon (Crystal) save file from comp to actual cartridge? - pokemon crystal gsm

I see a very old game Pokemon backup file of RIN emulator on my computer, but here I found Pokemon Stadium 2 game in a box. I would be real crystal cartridge on eBay, or buy something, but I want to avoid the backup file on my transfer model in the game, to play for another 7 hours.
Who knows how?
