I have installed all versions of GNZLAP projects and all looks fine, also I have installed VOZ AI so now the NZ international airports[check out NZAA] are full of local airlines.(the only problem I have encountered was some of the double up title files between VOZ AI and GNZLAP, easy to fix with either deleting the VOZ aircraft or changing the aircraft CFG file.FSX will inform you with which aircraft have doubled up.)
Now fsx AI NZ looks great and you can now easily run AI settings at 100% with better frame rates than the orginal fsx AI.
I will attempt to install other fs9 AI projects into fsx and let you guys know if they work.
TIP# make a backup of your fsx NZ Afcad files as some of the GNZLAP files will place aircraft in weird places eg NZAA.
