Thanks for your testing, but why you have not try NeJv6.91 with the NeJ v6.9.4 patch? But good to know that v6.91 works.I have installed NEJ2V691 with BWP megamod and beyond the normal problems (2 Yoshi's, Shar-Tel has lines from BG) I haven't noticed anything. I'm still in Athkatla (both Nej parts done) but so far so good.
Greetings Leomar
Of course I used NeJ v6.9.4 patch with NeJv6.91 (sorry for not mentioning it but I thought that was clear by itself, you know if there is a patch for something you usually use it), in install order I have installed it at the same place as mentioned in BWP guide with BGT parts installed after restored txt (if you are wondering). I'll keep using it from now on since it seem to work great (nothing game breaking happened so far )
