Wait a minute. Back up and re-read that threads title again. It says "what ios' games use to run". There is a difference between a cios and an ios. A ios is nintendo and cios are custom created ios'. Dealing with cios', youll want to install cios38 rev14. Ios that your talking about is in that thread. For instance... NSMB uses ios53 so in order to get that game to run, youll have to have the newest ios53 wad installed on your console. To get ios' installed, you install those via wad manager. Cios' you use the cios installer to install those.
