Roliana

Are there any hacks for that?

Not hacks, so to say, games like this, and solia, are heavily monitored because of the low level of people. Like Gaiaonline, you can spam the forums almost freely because they have so many people, the second you spam solia, and roliana, you're banned.

There's some stuff in Roliana.

I know how to get a bunch of un-released skins.
It's probably fixed now, or they released them.
I haven't been on in forever

Roliana has near nothing for hacks, it's because no one tried yet ._. There is a glitch for one of the games though.
