I'm asking exactly because I couldn't find anything about that so plz don't be mean.

My question is - for multiple .iso games, how to switch them during playing? Basically I have them on my memory card, not UMD, and when the game prompts me, I have to switch to the other .iso file. The thing is - saving is treated as still using the previous disk and the save can't be loaded on the other one so it needs to be switched in the exact moment I can't save. Installing the game doesn't change anything. Now I know it is possible using ppsspp but I'm asking if there's a way to nicely merge both disks or just switch them when I'm playing on psp or do I always have to use ppsspp and create saves on the right disk? It's pretty annoying but if there's really no way...

Now before you ask - I am aware UMDgen exists. I tried adding the 2nd disk files to the 1st one but they shared names so it didn't work and treated the merged disk as the 1st one. No idea if there's a way around it to make it work. And no, the game in question isn't FF type 0 which has a patch and a simple way to make it work. It's actually Gakuen Heaven but I'm asking in general as there are more multiple UMD games.
I'm not sure about using PSX2PSP since, well, they're psp games, not psx ones but every single tutorial I could find was either about psx games or FF >_> If there's a way to, idk, just add a command to VSH.txt to make switching between .iso as easy as in ppsspp, that also works. I'm just asking if there's a way to do it on psp.

I'm terrible at searching.

But I did exactly as in this thread and while iso_change seems to work properly [it appears normally when I use L+R+♪], the disk isn't changed in game, hmm... And yes, both discs appear normally, I can choose one of them, after pressing ○ nothing happens. I tried to find disk change by Takka but the links appear to be dead so my question still stands.

Haven't used my PSP in a long while but you can find working links to Takka's plugin on this page :-

Huh, I'm not sure of the exact reason [if anyone's willing to explain, I'm all ears] but Takka's plugin worked correctly only on NP9660, while on M33 it let me switch only from disk 2 to disk 1. No luck on Inferno.
I suppose my initial question was answered, then. Thanks.
Again, if anyone knew what the reason for the plugin not working correctly on two out of three modes might be, plz share. I'm curious mostly as I haven't seen others having similar problems but it might be an issue with just this one game so it's not all that important. Just noting this here.

If I still had my PSP i would try it myself to see if I could find a way of doing it. Maybe changing CFW would fix it. Good luck anway.

    yall im torn... ive been hacking away at tales of phantasia GBA (the USA version) and have so many documents of reverse engineering i've done
  • TwoSpikedHands @ TwoSpikedHands:
    I just found out that the EU version is better in literally every way, better sound quality, better lighting, and there's even a patch someone made to make the text look nicer
  • TwoSpikedHands @ TwoSpikedHands:
    Do I restart now using what i've learned on the EU version since it's a better overall experience? or do I continue with the US version since that is what ive been using, and if someone decides to play my hack, it would most likely be that version?
  • Sicklyboy @ Sicklyboy:
    @TwoSpikedHands, I'll preface this with the fact that I know nothing about the game, but, I think it depends on what your goals are. Are you trying to make a definitive version of the game? You may want to refocus your efforts on the EU version then. Or, are you trying to make a better US version? In which case, the only way to make a better US version is to keep on plugging away at that one ;)
  • Sicklyboy @ Sicklyboy:
    I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version
  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
