If you want to access XXL's assets, your best start is by using AdrienTD's ELB tools
With it you can recover alot of 3D models, textures etc.
Good luck on attempting anything with XXL!
If you need any extra help I'm around
Note that there might already be a XXL Remake coming out
hope we'll have an announcement at end 2020 / before 2021
Ngl, would be surprised if it doesn't release end 2020/early 2021
i talked about announcement, not release
for how long did they work on XXL2 remaster?
5 months I think? I can't be sure
