Besides the level select, everything on that page and in the various sub-pages is mine. There's a lot of it.
Some unused graphics, but not all, plus some unused sound effects.

Minor Contributions

Either small findings or adding content that other people found.

Arcade

Unused UFO graphic that's relatively common knowledge at this point.
Credits that are seen for four frames when the game boots up. I didn't really discover this; Anyone who has ever run the game in MAME has already seen it.
The Zen-chan-like enemy graphic was discovered long before TCRF existed.
Pretty much my only original contribution was the anti-piracy information. All other content (except for the unused music and sound effects found by Furrykef) are known facts about the game that I just added to the article.
Unused music track that was already known to be unused.
