Base Images
Base images are pretty much analogous to scratch pad graphics sometimes found inside the ROM of games for older game consoles. They were used for making and drawing the majority of the game's graphics. While most of them have sadly been deleted, there is still a few of them leftover in the game data, offering a tiny glimpse into the process of making the graphics, and also a few ideas that didn't make it into the final game.
While some of the final game's graphics do appear in them, every single frame for the sprites presented on this page are unused. They're only listed here for the sake of completeness.

There are also images which is not grouped with the base images, but can be found within sprites used by the game. The reason for this, if I remember right, probably had to do with keeping RAM usage, as well as exe size as low as possible. While they are already listed on the main unused graphics page for the game, they're still documented here for completeness.
