Lots of people go straight to the guard at the front gate or the Trepie in the cafeteria, but these two are so easy to beat when you only have the starting cards. If you need Elnoyle, Abyss Worm, Tonberry King, Adamantoise, etc. just head to the library as soon as you get your first cards. These two are seriously bad at Triple Triad and drop everything you need in the early game.
The Playstation emulated version should have rumble and omnidirectional movement. AFAIK, the PC version doesn't have rumble and is limited to 8 directions.
Edit: The upside of the Remaster version is that Angelo Search can find a bunch of items that you could only get from Chocobo World.
The FF wiki says that Chocobo World is playable directly from the original PC port.
