The game I used was the special edition for ps1.

I've seen cheats for other games such as Ridge Racer or Colin Mcrae to make the cars become smaller or to add huge tires, so I thought that there could be a cheat for wipeout 3 to make the ships look different, but I didn't find any reference to that. Those small ships don't look wrong or spoiled, that's why I thought there could be a way to obtain them without having to modify the file names.

Another thing I tried was to use the tracks from the first wipeout on wipeout 2097 as they have the same structure and file names, and some are even the same files in both games. But it didn't work, the game hung up after the loading screen.
