Add support for PSX games

[junkitself]

I realise adrenaline is generally the go to method for playing psx games, however, there are a few games here and there that are easier / better to get running via retroarch. as such, any chance of adding support for creating bubbles for psx games that run in ra?

I've opened an issue on Multi-Builder DRok17/Multi-Builder#6

Will look into it and see if it's possible.
