PS5 Modified PS2 ISO on PS5! Kingdom Hearts 2 FM Roxas Mod (Help!)

[itskeyexe]

(HELP) I Patched a PS2 KH2FM ISO with the 1.15 Roxas Mod SCRIPTLESS

using the modified iso, I packaged it Via @Jabus Ps2 fpkg tool.
it works incredibly well on my
JAILBROKEN etaHEN 1.07-4.03 PS5.

If you skip cutscenes that crash it (one in beast castle and one in trons world) and keep saving,
you can play as ROXAS on PS5!!!
Until.... THE TRON HOSTILE PROGRAM BOSS FIGHT...it becomes invincible.

I have tried to repatch and repackage it with a memory card saves past this boss and thought of modifying the save via ftp, but the ps5 encrypts the save somewhere and I have no idea if its possible.
I have also tried writing and patching in a new CONFIG file for it but that seems to have no affect.
If Jabu saw this maybe he would know how to add the right emulation or correct LUA or Config to get this playable 100%. The iso is compatible according to aldostools ps2config

IS THERE ANYONE WHO HAS A CLUE ON HOW TO SOLVE THIS?

This tool is amazing and being able to fully run modded KH2FM iso to completion on the ps5 would be a dream. I want to experiment further and see just how many moddified versions of KH2FM would run without psx2 on my ps5. Here is the video of what I tried and some gameplay I captured of the problem. Last thing Im going to try is repatching a iso with the script version and see if it works. Any ideas appreciated.

Heres my Video about the issue:

I think you'd have to decrypt the save on the system itself, which may or may not be possible on the PS5. It's possible on PS4 iirc. You can do it with Apollo or save mounter with debug.bin.

I thought the same I guess I havent tried it yet, i have a HEN 9.00 ps4 and was thinking of trying it on there with a modded save. Ill look into decrypting the save also. If the iso could have the correct config that may be the easiest option. This is a untested territory and I really want to achieve it. Thanks
