PW2 Jailbreak for adding opendyslexic fonts

Hi

I bought a PW2 with latest fw for my son, expecting to easily add opendyslexic fonts by way of the workaround I'd read about, not realising that the easy w/around (USE_ALT_FONTS trick) works only for the PW1.

So my question is, do I need KUAL for this, and in which case follow the Sticky, or do I need to just jailbreak it and install the font hack ? Or do I need the fonts override Kual menu and if so, the python package too, as well as KUAL?

Hoping someone can point me in the right direction

Thanks all

Timos
