For this you will need to have linked gamess and nbo.
Here's an example input that works:

And here's the output:

* It runs with PCM, but the results seem nonsensical, in addition to it finding a lot more fragments than without PCM (the latter thing can be amended with NAO)
* If I use DEF2TZVP with PBE0 and DIRSCF=.TRUE. It'll get stuck during the NBO run at
It's not consuming any CPU at this point (nor is nbo). I'm running w/o DIRSCF now, but it's very slow, and requires ca 30 Gb of scratch space even for a small molecule like this one.437.

is not necessary for this run. You can simply use NBO $END instead.
