The phone need to be able to execute webgl content, if that's not the case I can't do anything. In all cases, it's not adapted for touch controls for now, the UI need to be completely different and missing some controls to rotate/zoom the camera.
I don't understand your question about database, roBrowser use the file you gave to him.
For now it just read all database .txt files (old files), try to parse some lub files (but can fail), and don't even touch about lua and xray files.
As for the lua I don't know if I should go to run a VM in another VM, great change to be slow in my opinion.
I mean can it also connect to the sql database of a client based server (mysql)? Which will make players be able to play on both client based and browser based.
EDIT: Ah so as I understand it does not have a sql db but a txt db?
