=Resolution=
== PS1 Native resolution ==
Games are always 4:3 with any resolution between 704x480 NTSC / 704x576 PAL (the bios initialisation screen) and lower:
* Horizontal: 256 (rare e.g. Dragon Warrior VII), 320, 368 (occasionally 384 e.g. SF Zero 3 but not X-Men vs SF which was shrunk to 368), 512, 576, 600, 640 or 704
* Vertical: 240 (NTSC), 300 (PAL), 480 (NTSC), 576 (PAL)
Tekken 3 uses a strange pixel area of 384x480. Regardless of the screen area, the aspect ratio is still 4:3 for all PlayStation games.
Very common resolutions : 320x224 for NTSC and 320x256 for PAL.

<pre>
The main issue here is that it's mostly not doable to emulate the GS efficiently with the rest
of the hardware because the RSX is just not meant for this task and cannot emulate the GS on
its own while all the available SPUs and the PPU are already mostly fully used to emulate the
rest of the playstation 2 hardware, this explains why sony never could finish the ps2_softemu
and that it reached a stalling step.


==PS2 Native Resolution==
I honestly have no idea on how it would be possible to get over the ps3 hardware limitations to
Video output resolution: variable from 256x224 to 1280x1024 (not 1920x1080) pixels.
perform a full ps2 emulation without any of the ps2 hardware present on the console, one thing
for sure is that the emulator would have to be entirely rewritten and optimized like no other
ps3 software has been.
