- Update software renderer to the gpsp renderer (fast enough to render on slow hardware) - Convert audio emulation to fixed point (since float is slower on these systems) - Add PSP as a target for SDL - Add PS2 as its own target, though it's still using software rendering Thanks to @kikugrave for adding the initial psp boilerplate and inspiring me to finally finish the ps2 port!
