Good Emulators for Linux

[Termer]

Hello, Tempers! I've been fully switched to Linux for a few months now (I was dualbooting before), and I've noticed that I have nothing to play my ROMs with. I run an Ubuntu fork, so anything that supports Ubuntu I can run. I have ROMs for the following:
Dreamcast
N64
DS
GBA
GB(C)
PlayStation
PlayStation 2

Thanks for your help!

I think you can use Retroarch to run pretty much all of those platforms.

EDIT: Except PS2, you might want to use PCSX2 for that
