Ok, I think I figured out why the game crashes in Costa De Sol. Barret is in the Inn talking after the cargo ship. Whenever that happens, it causes something to screw up when you also have the Save Point options open.
Honestly, I think the save point is going to have to be moved somewhere else due to that. Putting it on the beach would work, along with putting it in front of the hotel, in the bar, or in front of the entrance/exit for the town.
EDIT; Ok, I went up to the Correl hills, then backtracked to Costa De Sol to see if things changed with Barret gone from the hotel room. They do. Before, right after the Cargo Ship pulled in and Barret was in the room talking, it caused the save point option text to mess up and the game to crash. Once Barret is no longer in the hotel, the issues disappear. And Barret will show back up in that hotel later on in the game when you're in the town.
So yeah, the save point needs to be moved, especially for players right after they leave the cargo ship. Leaving it inside of the hotel causes problems. Move it someplace else and the issues should disappear.
