RCT Save Game Modifier Version 3.13

To take the description from another source:

Edit your RCT1 saved games in a new way! You can design new scenarios, generate random terrain maps, modify the research items, change vehicles, etc, etc, etc! This is not a "trainer" - it works only on saved SV4 and SC4 files. You should keep a copy of your original files in case the edits result in RCT not working properly. It is intended primarily for Loopy Landscapes. You will need the Drexler patch for many of the edits to be usable in RCT.
