Hi hii
apologies this might be a question for modding PS2 games in general and what can be done with them. However I have grown more interested in having my own Personal copy of Persona 3 FES with the mods of my liking installed that I can use to more easily access my modded copy of Persona 3 on different devices and or possibly actual Playstation hardware (after modding)
I poked around myself to see if it was at all possible and noticed that in PCSX2 the files of my modded persona 3 fes copy are completely in different states than the vanilla unmodified files found on the ISO itself (as expected),
I have my own doubts if what i would like to do is possible, as along with that there are mods that only work on PCSX2 and cheats that one has to use to make a few mods function entirely within PCSX2 to begin with
Whether the answer is yes or no, or "its way to complicated for you to even attempt" is fine, this is a curiousity I can't find an answer too, maybe because it's not possible to begin with
however I wonder if it is possible to compile a modded copy of P3FES into a ISO and play it in a similar manner to a vanilla backup of P3FES.
Sorry for the long read, if there are any issues caused by this post I will take it down upon request
