After installing d2x in ios 249/250, the disc channel prompts me to update whenever I want to play some newer games. I figured out that newer discs check to see if anything is installed in ios 249/250, and then require an update. My plan is to stub ios 249 and 250, then install d2x under 248/247. Is there any homebrew software that can stub an ios? Or can I just delete the cios with Multi mod manager and will it stop asking me to update?
