First, a reality check. You cannot drag a .ISO into a program and magically get a .PKG in 2 seconds (not a working one, anyway).
Why? Official PSP PKGs from PSN are encrypted with keys specific to the console you download them for. A raw ISO is just a disc dump.
However, if you have a Custom Firmware (CFW) PS3 (like Evilnat or Rebug), you can bypass the encryption checks and build your own packages.

Converting PSP ISO files to PS3 PKG files allows you to install and launch PSP games directly from the PlayStation 3 XMB (Cross Media Bar) dashboard. This process is primarily used on consoles running Custom Firmware (CFW) or PS3HEN. Popular Conversion Tools
To perform the conversion on a PC, several specialized community-developed tools are used:
PSP to PS3 Executable/GUI: A dedicated tool that takes a PSP ISO or CSO file and packages it into a PS3-compatible .pkg file.
TrueAncestor PKG Repacker: Used for advanced users to manually unpack and repackage files into PKG format.
Webman Classics Maker: A Windows-based tool that can connect to your PS3 to create launcher PKGs. General Conversion Workflow
Preparation: Download a PSP game in .iso format and ensure you have a "PSP Launcher" installed on your PS3 to boot the converted files. psp iso to pkg converter ps3
Conversion: Run the conversion software on your PC. Select the PSP ISO, customize metadata like the game title or icon, and build the package. Installation:
Transfer the resulting .pkg file to a FAT32-formatted USB drive.
Connect the drive to your PS3 and use the Package Manager to install the file.
Launching: Once installed, the game appears on the XMB. It typically requires a separate "PSP Remaster Launcher" to run. Key Considerations
Compatibility: Not all PSP games are compatible with the PS3's internal emulator. Many will experience graphical glitches or performance issues.
Alternative (ISO Mounting): Instead of converting to PKG, many users prefer using webMAN MOD or multiMAN to mount and play raw ISO files directly from the dev_hdd0/PSPISO folder, which is often considered more stable.
To convert a PSP ISO into a PKG for play on a modded PlayStation 3 (HEN or CFW), you typically use a "Remaster" or "Minis" conversion tool. This process wraps the PSP game within a PS3-compatible emulator shell that allows it to appear and launch directly from the XMB (Cross Media Bar) Popular Conversion Tools PSP2PS3 (GUI)

White Paper
Title: Legacy Interoperability: A Technical Analysis of PSP ISO to PS3 PKG Conversion Methodology Subject: PlayStation 3 Emulation Layers and Package Porting Date: October 26, 2023 Article last updated: March 2025
A PSP ISO is a bitwise copy of the Universal Media Disc (UMD). It contains the file system (ISO 9660), the executable files (EBOOT.BIN), and asset files. The PSP executable format is typically an encrypted ELF file wrapped in a PBP container for digital distribution, or raw binary data on a UMD.
Even with a perfect conversion, you may encounter problems.
| Issue | Likely Cause | Solution |
|-------|--------------|----------|
| Black screen after launch | Incompatible ISO or bad emulator settings | Try a different PSP emulator shell (extracted from a different PS3 firmware). |
| No sound | The converter stripped the audio incorrectly | Re-convert using “Keep original audio” option. |
| Save game corruption | Wrong Memory Stick size | Rebuild PKG with larger emulated Memory Stick (e.g., 128MB). |
| Stuttering framerate | PS3 is trying to upscale too aggressively | In the PS3’s settings, force 480p or 720p output instead of 1080p. |
| Controller doesn’t work | Wrong mapping configuration | Edit the PARAM.SFO inside the PKG using PS3 Tools. |
The PS3 operating system utilizes a sandboxed emulator application located in the firmware flash (/dev_flash/pspemu). This emulator mounts the PSP game image and interprets the MIPS instructions. The conversion process effectively wraps the ISO into a format the psp_emu layer recognizes as legitimate.
Unlike a raw UMD, the PS3 emulator expects a specific container format known as PBP.
On the PS3, a PKG (Package) file is an installation archive. Sony used PKG files for:
When you buy a PSP game from the PlayStation Store on your PS3, you download a PKG. Installing that PKG places the game into a PSP emulator shell specifically designed for the PS3’s hardware.
A PKG file is an archive format used by Sony for software installation on the PS3. It contains a specific directory structure (/dev_hdd0/game/) and encrypted content. To run PSP software, the PKG must mimic the structure of an official "PSP Minis" or "PSP Remaster" title.
