PSX-Launcher IS ABLE to BOOT PSX-Backups WITHOUT a SLIDE-Card-Trick on V9 and up.
I tested it on a FAT-PS2-SCPH50004 and it loads the PSX-Backup WITHOUT a chip, or Swaptrick (while opening the drive with a knife.).
PSX-Launcher is also able to boot to PSX-Mode on older models, but NOT ABLE to boot backups.
Test it this way:
Boot uLE with a trigger-disc.
Swap the disc to a PSX-Backup, by using the EJECT-Button.
Start PSX-Launcher with uLE and your Backup loads through the PSX-Browser.
That is why he said, it is only working on V9 and up.
PSX-Backups ARE PLAYABLE ON V9 AND UP, WITHOUT THE SWAP-MAGIC-KNIFE/CARD-Method.
Hope you all get it now.
I tested it and I'm sure V9 (+up) could also boot backup, if you switch your original-disc very quickly with the EJECT-Button, after it loads the disc (PS1-Logo appears, or shortly before)
