I don't know about the PSClassic hacks, but remember you need a patched kernel + patched SDL2 ...
I won't go too deep into this, but it's a complete mess.
I still somehow managed to get any Linux distro working on it, I have the kernel's source and had to recompile it with different options.
It works, but it is hindered by the binary blobs, mainly the PowerVR GPU driver which is stuck with a certain version of MESA and a bunch of other libraries since it has static links to them and won't work with any other library.
Weston is the only compositor who can properly load the driver and activate the HDMI output.
That is, if you want GPU hardware acceleration.
Otherwise you can use X.org with the Gallium drivers which are software based.
Which means you're stuck with Wayland, there are no X drivers, which in theory is not a bad thing, but the actual state of Wayland is... well, not that good, even on Debian which has fully embraced it.
