I'm curious why the Genesis runs were removed, given that the Invincibility Cheat requires pausing the game, entering a lengthy sequence of inputs, followed by navigating a test mode menu before returning to the game. All of those steps would be obvious in a run, and using it could simply be banned... rather than banning the entire Genesis port.

See this video for details regarding the test mode menu:

It's also concerning that this action seems to have been taken without any community discussion. The SRC site moderation rules make it clear that community involvement should be involved in leaderboard management. See https://www.speedrun.com/support/learn/moderation-rules for more details.

Anyhow, here's the two recorded runs I did in 2019 of Zero Wing (Genesis) Any% Easy that used to be up on this board. One was a baseline, the other was a no-miss run with pretty good boss kills.
