Hi, I decided to try this beta tool with Final Fantasy X Remastered PS4 version. Since this game has cross saving with the PS3 I decided to try something. I created a PS3 save at the first save point on the PS3, I used Bruteforce SaveData to decrypt the PS3 save, applied the cheats "Al Bhed Translated" and "200 Lightning Evades", used the MemorySumChecker.exe tool to fix the checksum, encrypted the save, and tested it on the PS3 to make sure it loaded.
Thanks for testing and sharing your feedback.
Btw, you could have used Apollo PS3 to patch and decrypt FF-X saves directly on the ps3.
Using the Apollo tool on the PS4 I dumped the decrypted bin for a FFX at the same spot. I decrypted the PS3 save file again with the cheats applied that worked on the PS3. The PS3 save file had a 27KB SAVES file which is the same size as the bin file dumped from the PS4. So I renamed the SAVES file to bin and I attempted to swap them with Apollo. I tried using the import decrypted save function to import the bin, but wasn't sure where it would look for the bin when importing. I tried swapping the the dumped PS4 bin in data/apollo/temp/gameID folder/bin with the modified bin, then running the import, but that didn't seem to work. So I'm not sure how the import works with this tool.
Edit: I confirm the bug, the importing decrypted files wasn't working in the public beta. It's fixed now and will be included in the first release.
I'd suggest to "enable debug logs" from Settings before trying, so you can share the logs in case of issues and I can get a full picture of what is going on.
Anyways after playing around for while I decide to try swapping the file with PS4 Save Mounter, I mounted the PS4 FFX save, FTP browsed to the mounted location, backed up the bin file, deleted it, then put in the modified PS3 SAVES file that I renamed to bin, and unmounted the save. Loaded up the game save with no issues at the beginning and I was able to read an orb on the wall with the Al Bhed language fully translated. Nice! So the PS3 BruteForce cheats can be be applied to this PS3 game since the file structure is so similar and just swapped it with PS4 save. Hopefully BruteForce adds PS4 functionality in the future as all these awesome tool develop and people discover PS4 cheats.
Not sure if you know, but if save file format is identical, then you can avoid all the decrypt/encrypt/move-from-ps3 stuff and just apply any BSD cheat codes directly using Apollo PS4.
You just need to copy the "savepatch" code file to /data/apollo/data . It should be named CUSAxxxxx.savepatch to match the Title-ID of your game. Both Apollo PS3 and Apollo PS4 can handle every BSD cheat code and Save wizard code, including many custom hashes, checksum, encryption schemes and more.
You don't even need any "memsumchecker.exe" for FF-X. That custom checksum is already supported.
I think that many games that have ps3 and ps4 versions can probably share codes too, but it needs to be tested and checked on a per-game basis. Persona 5 is another one that save-games are identical.
Regarding Bruteforce Savedata, from aldostools comments he's not actively working on it, and he actually recommends using Apollo too.
