Identyfing an issue
I tried to add the developer mode to my brothers xbox one (yeah i know it could have run worse than the series but he has a one and likes old games) i downloaded the ps2 emulator without any issues, but when i tried to upload a game through the xbox device portal, it didnt work, it said there is no more space on the disk, or something very simmilar. Now i did it the same way on my series s and it worked fine, i also set the dev storage to like 25 GB just to be sure it works. But it didn't, if anyone had simmilar issues and know how to fix it ill be super greatfull
