Definitely couldn't do this all straight on my 3DS. I needed assistance with PC tools, both made by myself and made by others. Most of the data is compiled into GRPs, since that seems to be the only viable option for holding a lot of data externally with as few files as possible. The graphics and levels are stored in a custom-compressed format that would take far too long to compile in PTC.
