PS2Unit

PS2Unit is a script for compiling & installing CUnit for the Playstation 2 EE core and IOP.

I decided to make it because CUnit doesn't exactly make itself easy to compile in the first place, and it's a little extra tricky to get going on the EE, and a lot harder to get going on the IOP.

It's not impossible and definitely not difficult for anyone who's used to PS2 programming, but I thought it'd be nice to help out newbies like me.

Usage

You will need ps2dev installed with the PS2DEV environment variable set to the location it was installed to - see https://github.com/ps2dev/ps2dev to ensure you're set-up fully.

Run the following commands to download this repository and compile CUnit for EE and IOP.

git clone https://github.com/telyn/ps2-cunit-port.git
cd ps2unit-cunit-port
./install-cunit.sh

For an example of a CUnit program and its compilation for the host machine, EE, and IOP, see the 'test' directory.

IOP-specific notes

CUnit requires functions to be imported from the following IRX modules:

• alloc.irx
• stdio.irx
• sysclib.irx
• thbase.irx

Of those, all except alloc.irx are loaded by default by PS2Link (or already loaded by the PS2 BIOS, I don't really know) - so you don't need to load them prior to loading a program compiled with CUnit.

To load alloc.irx prior to loading your program:

cd $PS2SDK/iop/irx
ps2client execiop host:alloc.irx

n.b. at least for me, ps2client execiop remains
