When i go to download the 1.9.0 emulator it never seems to be available for download, Should there be a change in usable version as i see the rules state 1.9.0 but i cant find a way to get it

Can confirm that the official ePSXe downloads seem to be offline. The page is up, it's just that the downloads do nothing when you click on them.

That being said, there's already a run performed in psX v1.13 which is already on the board (see this thread for more info), so you should probably be ok to use that one (though a confirmation from a mod would be awesome).
