Wow, I did a search on another forum and just found a really ghetto way of booting your PS1 backups...
I got my Star Ocean 2 backup to work by doing this:
- Booted PStwo with the fliptop open/ejected.
- Went to the browser.
- Put in my original Xenogears PS1 game.
- Closed PStwo fliptop normally, but left my stealth fliptop thingy open.
- PStwo detects PS1 game on the browser list, but disc is spinning slowly.
- Took the Xenogears disc out as it was spinning slowly, and put in the Star Ocean 2 backup.
- Closed fliptop completely, stealth and all.
- Selected the PS1 game icon on the browser.
Game boots up perfectly. /gg
