things you will need for this to work:
-psx4iPhone(works on all ipod touches and iphones)
-work PSX bios (scph1001.bin) *GOOGLE IT I WONT SUPPLY IT
-jailbroken software (for this tut i used 3.0)
-SSH client or iPhone PC suite (PM me for download if you cant find it)
-Patience (lots of it if you are using SSH clients lol)

Step 1:
open cydia and download the latest psx4iphone (may need to donate just scroll down and select Free)
once installed SSH to your iPhone and go to this location: "/private/var/mobile/Media/ROMs/PSX/"
if that location doesnt exist, make it.

Step 2:
In the location above ^^^ put the bios file there, make sure the bios is named "scph1001.bin" no quotes
**BIOS FILE MUST BE IN LOWER CASE OR GAMES WONT LOAD
Step 3:
copy your PSX isos to the above location and run the emulator and play it. make sure the Permissions for all files in the above location are "755"/"0775" depending on the Client you use.

Notes:

-some games dont run, use different Region bios, BUT MAKE SURE THE FILE IS NAMED "scph1001.bin"

-Some games are slow and glitchy, the emulator is not perfect peopledont expect EVERY game to run FULL speed.
