/vr/ - Retro Games

Is there no emulation general going these days? I don't know where to ask, so I guess I'll ask here: pic related is the virtual keyboard I get when using retroarch. I have no idea why it's in japanese and I've hardly used this computer at all. The only thing I can think of is that I briefly ran Castlevania Dracula X (with a translation patch) which may have set some retroarch default to expect japanese or something. For that matter, what are the important hotkeys/buttons for dealing with the retroarch virtual keyboard? It has always baffled me so I mostly try to avoid it.
