Hi,
It's safe to delete files under GGame directory *but* you have to back them up before...
Copy whole mtd_tlib partition to your USB disk.
Also take snapshot of your firmware with dump maker utility.

One swf file at mtd_tlib is the content manager "menu". If you delete that file, you probably can't enter that menu again.
Again,if you have CI+ device, deleting this files might be put your device to boot loop.

For me, It's better to not touch those files. You can delete most of them (like children swf or space ship thing..) for CI devices.

Dump utility makes only bml1-9 dumps (lite version). So you do not get tlib dumped. If you want full dump, i could give your first version of dump maker (not restricted).

Use other free space on TV to place your files (i personaly use /mtd_swu) ,
you could use /mtd_down, but after every Internet@TV reset it is being formatted, so , it is not the best place

You could use mount --bind... as well.

This version makes all dumps you ever require for restoring your TV (rw areas like /mtd_rwarea /mtd_tlib and so on are dumped as well). Dumping takes time, so be patient.
