I rented this game for what must’ve been weeks and for some reason there were only two gems between me and that 120% specifically on this map.

I unlocked everything else, even the power to have Sparx point out the nearest gem. And the two missing ones were on top of a set piece building completely out of bounds. Bought the game for my birthday and the save files didn’t work and the gems weren’t on top of the towers anymore.

Edit: Can anyone make sense of why that might happen on a rented ps1 game?
