Here is now after several tests, a "new" homebrew PS2 compatible with our PS4:
Small booster booster, Beats of Rage (also known as BOR) is a free 2D fighting game engine designed by the Senile Team. It is originally released as a video game tribute to Streets of Rage 2 but with characters from King of fighters.
You will be able to create your own mods or retrieve existing ones (BOR.PAK) and launch them on your PS4.
I have compiled 2 different versions that will launch Beats of rage for one and a MOD Kill Bill for the other using UlauncherELF.
- The first [PS2] Beats_of_rage.pkg, including BOR base, you can edit this version to add your personal MOD or whatever you want.
The passcode is 000000000000000000000000000000 for decompiling the .PKG.
You will have to decompile the PKG, then with CDgen replace the file BOR.PAK present in the file image / disc01.iso
disc01/BOR/BOR.PAK
- The second [PS2] BOR_Kill_Bill_MOD.pkg, including a MOD Kill Bill, to serve as an example ^^.
Launching Tutorial:
- Install the pkg of the desired version (Debug setting, etc ...)
- Launch the application
- On the UlauncherELF menu, press O FileBrowser
- Select CdfS: / by pressing O
- Then select the BOR folder by pressing O
- Start BOR.ELF by pressing O
- Play ^^
Ps: it is possible to automate the launch of MODs by modifying the path in the SYSTEM.CNF file
