rinCheat VS p4g-saveconv

save-game cheat patches (based on rinCheat codes)

2) I was so desperate I ended up installing and launching rinCheat, but unfortunately it seems not able to find the cheat list, despite me preparing it and putting it in the correct folder with the correct title ID as explained on their GitHub. Does anyone have any ideas on why that's happening?

Honestly not sure about p4g saves but I did find this tool to transfer from vita to PC. You could try renaming the save like I mentioned as well, like i mentioned in the first comment (assuming the names are also different for p4g between steam and switch)

That's already a thing... though not official, it works.

Is it possible to convert P4G PC save data to Vita save data? I know it's possible to convert Vita to Pc, but that's not what I'm looking for. I found this github page, but it didn't work for me, is there something I'm doing wrong?

I used this tool: https://github.com/zarroboogs/p4g-saveconv to convert the Vita to PC save but it looks like you've already done that.

https://github.com/zarroboogs/p4g-saveconv I've been able to get this script to run, but when I place the converted files in the correct Vita directory, they're not detected :(

Once you’ve got a recent version of Python 3 installed follow the usage instructions; the basic usage is python /path/to/the/script.py /path/to/your/backed/up/save/directory, though on Windows you might need to type py instead of python. It’s a command-line app, so it expects you’ll run it in a terminal window (ie cmd.exe).
