Thanks to the unlimited, high-end, state-of-the-art, software-rendered technology of Blast Processing™, the Sega Mega Drive/Genesis is capable of sprite and background scaling/rotation, also known as "mode 7" (even though mode 7 is for backgrounds only) by video game experts on forums such as this. But which games use the Blast Processing-powered scaling and rotation? Let's try to list them.
