You dont see anything or you choose not to read it all. Yes every firmware is affected. Yes every app that uses title keys is affected. No you cannot use any of those methods to get games your after any more.
i can yes, they are all in files labeled under their respective systems which i have collected over the years and now each folder is full of classics like silhouette mirage for ps1 , tales of the abyss for ps2, Chrono Trigger on snes, Fire emblem Gaiden on nes and many more great titles all at my disposal. Plus it helps with my gamecube portable project having access to every single game on the system.
