Hi.

It's not possible to install the G1 packs at G2.
The two packs you mention is created to load into YEM and then transfer to G2.
However, if you did register your G2, you can log in to your customer account at (if you're in Europe)
https://hub.europe.yamaha.com/download?product=Genos2 or at the region you belong.
There you will find all the addonpacks downloadable for free.
Yamaha has reworked and tweaked it to G2 format, and they will play correctly at G2.
