I thought romhacks org was shutting down?
Hacks like these are perfect examples why the world needs a hack site.

Hell yeah! These were really fun for me to play as a kid, and I did like the Raptor ending in particular, but I always wanted a bit more, given how much effort it took to get to the end. Especially the Grant campaign.

As a kid, though, I just wish the map would change and display the next level on the map once you finished the third stage. Even if you couldn’t pick your route anymore, it was always frustrating not really getting to see my progress after that point.
