IntPe9 is a packet editor whom only operates in userland. It has a GUI frontend and it can have different backends to get the packets. In theory you are free to create any backend as you wish, however i use a skeleton which defines some basics.
O yes, please do. If you want to have a game supported go start writing another Core and submit it. Big chance i will implement it.
GPLv3 as sharing is caring, and when ever you extend/use/modify/fix any of IntPe9 you should share it again!
My name is Intline9 (Intline9@gmail.com) and i created this Packet Editor (IntPe9). I wanted to have a good tool to analyse programs and there protocols.
