[PS4] Need help converting a Witcher 3 save between two different CUSA codes (CUSA01440 → CUSA01439)

CSSFontFace-Exploit Host on the XIAO ESP32-C3 - 100% Offline

Hi all, So first thing is that I have only tested this on one PS4 which is on 9.00. In theory, it should work on the outlined supported versions though but if not, here is fair warning that I can't confirm anything other than 9.00 on a slim. With that out of the way, if anyone has one of those XIAO ESP32-C3 boards doing nothing, which would not be a shocker really, there is finally a good use for the tiny little thing!! Here is a random listing for the board to confirm. I have put the CSS FontFace PS4/PS5 exploit source as of sometime yesterday or so into an offline webserver host and since this exploit doesn't need USB control, the XIAO ESP32-C3 has found its purpose in the world! -Steps to use- 01 - Download binary from link 02 - Flash XIAO ESP32-C3 board with bin file. 03 - Connect XIAO ESP32-C3 to power source. Can be USB, battery or whatever. Can be via the PS4 as well but doesn't need to be; anything should suffice. 04 - On the PS4, set up a network connection and do the easy way and automatic everything. Run the test if you want when done and it should get an IP address and fail internet test. 05 - Back out to Settings. Scroll way up to the top and pick User's Guide/helpful Info 06 - Pick User's Guide again. 07 - It should default to the Auto Jailbreak being unchecked and cache the page as soon as it opens up. 08 - Once cached, click the button to run the exploit. 09 - You should be good to go. Do what thou wilt I guess. I for some reason still mostly use Goldhen 2.3 so compiled a binary with it but I also did one with Goldhen 2.4b18.10. Both download links are below. XiaoESP32C3_CSSFontFace_XploitHost_Goldhen2.4b18.10 XiaoESP32C3_CSSFontFace_XploitHost_Goldhen2.3_9.00 SSID: Xiao_Xploithost Pass: password You shouldn't need to type any web address into any bar. 100% offline. Never connects to the internet. Also, here are some screenshots to show the basics of things. Just like being jailed and the user guide section running the page, being unjailed and the only firmware and console I tested on. Sorry if I missed anything but if so, let me know. On FW9.00 and with Goldhen 2.3 On FW9.00 and with Goldhen 2.4b18.10 Cheers and bless you all! - D0ng3r

Hi all,

I have an old PS4 save for The Witcher 3: Wild Hunt from 2022 that's tied
to CUSA01440 (EU). My currently installed version runs under CUSA01439 —
same game, same EU region, just a different product code (confirmed via
CDPR support and by checking the save's folder structure on a USB backup).
Because of that, the save doesn't show up in-game at all.

Save is 3 manual saves + a few checkpoints, ~16MB each, nothing exotic,
no trainers/mods involved.

Would anyone be able to help me convert/resign this save so it works
under CUSA01439? Happy to upload the files.

Thanks in advance!
