toukiden demo can't load savedata

[daniel229]

The game works fine with ppsspp except savedata.The savedata which created by ppsspp can be loaded in real psp,but ppsspp can't load it.

I tested JPCSP r3143 can load save

JPCSP 's sceUtility debug log (save and load)

PPSSPP v0.7.6-624 log (save and load)

AFIACT this is SCE_UTILITY_SAVEDATA_TYPE_FILES / GetFilesList misbehaving.

How did you even get the demo to work on PPSSPP in the 1st place? Did you have to decrypt it? If so, how?

I just get a Error loading file, Failed to load executable: File corrupt error in git revision 0.7.6-627

@solarmystic
use npdpc.exe Convert .PBP to .ISO,then use isotool decrypt eboot.bin

@daniel229

Thanks

EDIT:- Oh, isotool is a PSP application? Thought it was for the PC lol. Thanks again, tried to run it on my PC.

[solarmystic]

Holy mackerel... I believe we've discovered PSP-ception folks!

Iso tool. Works. In. PPSSPP.

A tool meant to work only on CFW'ed PSPs actually works in the friggin emulator. I actually decrypted the eboot.bin of the Toukiden ISO using PPSSPP.

Big thumbs up to the devs for making this possible lol This could be the key to making a heck of a lot more demos work lol.

Is there a publicly available link to this demo?

@unknownbrackets
Can I code in PPSSPP to let poeple know the decrypt method ?

[unknownbrackets]

I'm not sure I understand the question. But I did notice it's using directory paths. I think opening "x/y/z" maybe needs to create "x/y" if it doesn't exist automatically.

Hm. If the program running in PPSSPP can decrypt it, then surely PPSSPP should be able to decrypt it on its own too? :P Or at least it can't be that hard to fix...
