Support for it is no longer maintained.
I have added it only for fun.
If you want to use other PS1 emulator try POPStarter.
This emulator is designed to support PSX (PS1 Games) backups and play them on your PS2 via USB, Network, or Internal HDD.
- Only full 2352 bytes per sector images are supported.
By default only ccd, cue and bin files are displayed (case sensitive!),
but pressing R2 will remove the extension mask and display all files.
For more info read readme.txt in the attachments in the discussion.
Downloads are also in the attachments in the discussion.
