Just keep in mind back in those days I wasn't around, I was so behind, I bought halo 2 the day halo 3 released lmao (I didn't even know halo 3 was being released that day) I was a poor lad and finally saved enough to get halo 2 as well as the original MP mappack that day lmao. With me not really modding halo 2 very much at all, I learned pretty much everything by myself to make my own map as well as learn how to compile a mappack and make fixs etc for the broken packs. It took me maybe 1-2month learning process with just guess work, most mimieses maps are actually in killtrocity and phantom by default, anyways my own crash derby based map i threw into mimesis, i also included a specific gamemode to go with it so the map works properly as it can. I'm still noobish with halo 2 modding as is, I havent worked on halo 2 in maybe 3-4 months ish, so I basically forgot most of what I learned but it was fun to say the least! I say learned most by myself mostly because alot of tuts have broken images, broken english text so on and so forth.
I want to like aurora but due to how my games are setup I get hundreds of thousands of xbe's and xex files loaded into aurora and it makes it very difficult for me to even categorize it correctly lol, So I just stick to xex menu since I'm more used to it, to me it's faster also considering I have game series based games in one folder etc, idk how to explain it and it make perfect sense haha I just can't use Aurora or FSD because of that, now if I need to ftp or like do a quick game update test sure i'll use it but thats about it.
Well I'm glad there's someone like you out there that still cares about this stuff. I've been trying to find the allied mappack for over a year now at this point lol.
