I'm just curious about the reason as to why the new CFW (as opposed to 3.41 JB) doesn't run games unless the eboot/sfo files are pristine and haven't been tampered with.

I don't mind the eboot, but I'm sort of confused about the PARAM.SFO file. Stupid as it may sound, I actually edit those for the sake of adding remote play (even if most don't work) or simply to make the list more aesthetically pleasing (for example, some games have the title written in all-caps, such as FINAL FANTASY XIII, whereas I like to change it to Final Fantasy XIII).

I'm just trying to figure out if having the PARAM.SFO completely unharmed matters, or if it's just the firmware version parameter that I shouldn't change.
