PSPLINK allows you to start and debug homebrew for the Playstation Portable through USB. This can speed up development and make finding out what is causing a crash or bug easier. This page explains how to set it up and.

To get PSPLINK up and running, first the PSPDEV toolchain will need to be installed. This should contain the tools for the PC. So follow the instructions here first!

Each system involved in the use of PSPLINK requires a bit of setup for it to work. This includes both PSP and PC. Below are instructions for both.

Download the latest version of PSPLINK for the PSP here and extract it in ms0:/PSP/GAME on the PSP memory card.

Depending on the operating system used the setup on PC is different. Follow the on below which is relevant to your system.

On Windows a driver needs to be installed before PSPLINK can be used. To do this take the following steps:

1. Make sure the programs usbhostfs_pc and pspsh are available from the msys2 terminal. Otherwise download them here.
2. Start PSPLINK on the Playstation Portable and connect it to the computer through USB.
3. Download Zadig and start it. It will ask if you want to run it as administrator, click yes.
4. In Zadig, click on options -> List All Devices.
5. Select the entry "PSP" type B from the dropdown list.
6. Left of driver, select the libusb-win32 driver. Then click install.
7. Wait for the installation to finish, then disconnect the USB cable from the PSP.

Now PSPLINK can be used with Windows. See below how to do that.

With Linux PSPLINK will work without making any changes, but it will require using sudo for the usbhostfs_pc command. To make it work without sudo, a udev rule can be added.

To make using PSPLINK without sudo create file called /etc/udev/rules.d/50-psplink.rules (for example with sudo nano /etc/udev/rules.d/50-psplink.rules) and add the following content:

SUBSYSTEM=="usb", ATTR{idVendor}=="054c", ATTR{idProduct}=="01c9", SYMLINK+="psp", MODE="0666"

Save this, in Nano this can be done with Ctrl+O and pressing enter. The run the following command:

sudo udevadm control --reload

Now PSPLINK can be used without sudo. See below how to do that.

To be able to use PSPLINK with Playstation Portable homebrew, the homebrew will need to be build into an unencrypted .prx file. This can be done by running CMake like psp-cmake -DBUILD_PRX=1 . or if you're using a Makefile by adding BUILD_PRX=1 to it. The build the homebrew.

In the build directory, open a terminal and run the following program:

usbhostfs_pc

Keep this running!

Then open another terminal window and run the following there:

pspsh

Now we can simply start our homebrew on the PSP by running the following command in the pspsh window:

./myhomebrew.prx

Replace myhomebrew with the name of the .prx file which was generated.

When you're done with the current build, just run reset, rebuild the homebrew and try again.

Options available can be found when using the help command, but here are some notable ones:

• scrshot screenshotname.bmp for taking a screenshot.
• exit for closing PSPLINK on the PSP.
• poweroff for shutting down the PSP.

When a crash happens a crash log will be shown with a hint of what might have happened at the top and some additional info. If you wish to figure out where the crash happened, only the address is needed.

To figure out where the crash happened, open another terminal in the build directory and use the address shown by PSPLINK in the following command:

psp-addr2line -e myhomebrew address

Replace address with the actual adress and replace myhomebrew with the name of the elf file. This is NOT the .prx file and either has no extension or .elf depending on the build system used.

If no result is returned, make sure to build with the -g or-g3 option to make sure psp-addr2line knowns the function names and locations.

If you need any additional information, check out the complete online manual.
