Seems like I didn't write a post here about this project, it's time to do it.
As it's running in a web browser, roBrowser isn't OS dependent and run fine on Linux, Macintosh and Windows. It's also running on some smartphone and tablets but it depend if the system support webgl and I have to admit, it has bad control (not optimize for touch control).
It can also be run as a Chrome App, I personally use it to have a nice icon on my desktop.
From now, I tested it (and it's working) on Chrome, Firefox, Safari and Opera. It will work in future on IE11 when they will fix their rendering engine.
roBrowser is not a different game as Gravity built (Ragnarok Zero, Ragnarok Violet, ...), this project is intended to be another client for RO1, to connect on private servers.

(Thanks to report all bugs)
If you like roBrowser, you can help me improving it or
even thinking about doing a donation ?
The project is still on going, currently missing a lot of features to match the official client (trade ui, npc buy/sell, ...), but I'm working on it.
