::*Since 02.07.05 the PSX and PS2 discs are properly detected. PSX discs will show in XMB Game Column and you can launch the PS1 game from there. It uses ps1_emu.self default (you can choose Load or Load (Net), latter uses ps1_netemu).
#Switch to filemanager mode
#Browse to /dev_flash/ps1emu
#Select either one of the ps1 emulation SELF files


Note: Some games run better with ps1_emu.self (e.g. Motal Kombat) while others run better with ps1_netemu.self (e.g. Resident Evil 3). If it doesn't work, try another ps1 emulation SELF file.

=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.
 
I honestly have no idea on how it would be possible to get over the ps3 hardware limitations to
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.

PS1 Native resolution[edit | edit source]

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.


PS2 Native Resolution[edit | edit source]

Video output resolution: variable from 256x224 to 1280x1024 (not 1920x1080) pixels.
