To quote from the ReadMe.txt: Free PS2 Pub Gen

Automated Tool for flatz PS4- PS2 Emu PKG Technic.
  • Either place the Tool into the same folder then, orbis-pub-cmd-ps2.exe and the aithinfo_emu.txt within the template folder.
  • Or drop the needed files into the GUI and close and reopen her. You could then even move the App.
  • Drop the ISO onto the GUI and the Output Folder too or use the buttons to define one.
  • When you double click the iso and output textBox it will change between ISO or Output Path.
For the template if you use your own one till i did come to share a pkg with a template:
  • Place your Extracted PS4 PS2 Emu PKG with decrypted files into the folder '\template\template_pkg\'
  • Put template.gp4 into '\template\' the same goes for authinfo_emu.txt.
  • Files which we need to resign place into '\template\workfiles\' eg:
  • eboot.bin, ps2-emu-compiler.self, Image0/sce_module/libSceFios2.prx, Image0/sce_module/libc.prx and Image0\config-emu-ps4.txt.
Make sure to edit your gp4 file and Comment Out npbind.dat/nptitle.dat and trophy00.trp XML Style (<!-- -->). If you need them later the app will edit the project file and add them back.

If i have forgotten something in the readme, i'll add it later. For the tool just tell me on twitter what does not work for you and i'll fix as soon as possible.

Special THX to zordon605 and ps3120

Senior Member
for anyone having the issue of false positive and would like to feel safe. UPX is the software that is used to compress the executable. Typically this compression on executable alarms A/V software. You can grab the UPX from github and run the command below and that should fix the problem
 upx -d gengp4.exe
I have also downloaded orbis-loader.exe and gengp4-patched.exe on this forum (not included in the packages in OP) to automatically include original keystone when making fpkg. Those are also compressed with upx


I did manage to merge all split files of a Retail Game Patch but I cannot find a way to covert it in to a Fake Game Patch. Is there a way? my base game is already fake so I only grab the Latest Retail Game Patch to covert.


I am very new to fpkg creation, so anyone can help me with my below question. Thank in advance and sorry for my badass english.

Developing a new app that Instead of using gengp4 GUI version, I trying to use orbis-pub-cmd.exe to add file and directory into gp4 project file with this command

"orbis-pub-cmd.exe gp4_file_add [folder that i want to add] [local path of Image0 root] [gp4 project location]"

My goal is adding my custom files to right below "Image0 Root" like this
Image0 Root
→-----------My Custom File and folder
But the problem is [local path of Image0 root]. With requirement of this command, it requires me to add a local path of folder inside gp4.

What i want to do is adding my files right below "Image0 Root" without any folders, but i do not know which argument should i input into [local path of Image0 root].

Every time i try to add something like "Image0 Root" or "Root", it always creates new folder Image0 Root and Root inside of Image0 image.
