etaHEN 2.4B

etaHEN 2.4B Change log

- Updated to support the latest PS5 Payload SDK
- Fixed etaHEN and Cheats support for 8.40-10.01
- Added a Game Overlay menu to show CPU/GPU Temp and utilization, Local IP Address and other future states
- Added a Kstuff menu for options like downloading the latest kstuff from github, turning off kstufff autoload and more
- Added a Custom Background Package Installer for installing PKGs from internal storage from any directory (Requires DPIv2 enabled for 5.50+)
- DPIv2 can now download local files via url example http://192.xxx.xxx.xxx:12800/data/etaHEN/etaHEN.log
- Improved Cheats support, cheats with or without 0 sections are now supported
- Added Fix by TheFlow to Improve 2.xx PS4 PKG speeds
- Replaced the donation links in the etaHEN credits menu with ones to github sponsers
- Removed the non-whitelist app jailbreak option and moved it to an optional Legacy CMD Server option in the etaHEN Settings off by default
- Game Decryptor has been updated for the Itemzflow Dumper
- Updated the Plugin loader System
- The Payload SDK ELFLDR is now REQUIRED for etaHEN to load
- Replaced HTTP2 with Curl for better compatibility
- Added timeout for ShellUI to receive a response (will stop it from freezing if no response is given)
