@jackc so basically I purchased some 16GB cards and was able to flash the image to those. system started up fine on these. The initial cards were samsung 32GB that did not work. So topic can be closed.

Hello this is Gulshan Negi
Well, you need to reinstall the program and then check again. Hope it will work.

No change for a network connection.
Did you check in the menu if the network path was ok ? Could you check it ?
An other way may be gamelist corruptions, but on all systems except MAME would be quite strange.
