bonus game on disk
 

so i rediscovered my old jazz jackrabbit disk and discover there is a bonus game on it in a map called ffsw11, i recall palying it wayback in the past but now, with windows 10 i can't acces it anymore, anyone know what i am talking about?

You can play Jazz 1 in DOSBox and other DOS emulators if that helps, though ffsw11 doesn't match Jazz 1's level naming scheme...

Though if you mean Jazz 2, that runs in Windows 10 without any trouble.

perhaps i should have been more clear it is not a bonus level or anything for jazz jackrabbit but literally an entire different game on the disk, so i provide an imgur link with what the folder contains

i am unsure if firefighter is the actual name of the game

Looks like that's Fire Fight, another title by Epic Megagames. This page has some info about getting it to work on later operating systems, as a starting point.
