installing games?

im a noob to amiga emulation. i dont know all the names of programs you use except winuae. i stumbled across some games that were installed inside the emulator. e.g i couldnt use any other games for winuea except the game that came with it. it is a kaillera online emulator. ive downloaded some games and would like them to work on a kaillera client. so could someone please guide me how to do this or refer me to someone that can put my game onto a kaillera emulator.

also this emulator doesnt require an install to windows registry. i just downloaded it and was able to play it.

i hope i have explained myself ok. im not sure what im talking about with amiga emulators. i know quite a bit about snes emulators, but then again that one is very easy to work with.
