the reason why i want to request an emulator category is cause i wanna play on keybaord only . i noticed hat emulator is banned.

also that you can setup all the controllers you wanna play with

Emulator currently is banned for the original Jak 2 leaderboards, however if you are looking to play on keyboard/mouse, you are able to do so with OpenGOAL. It is the recommended way to play Jak 1 and 2 on PC due to it being more accurate and having more quality-of-life, as well as being open-source. Most recently, Jak 2 has beta support and is able to be played directly through the launcher.

Runs on Jak 2 OpenGOAL can be found here, and keyboard/mouse along with any controller of your choosing is allowed for run submission.
