I really like PCSX Reloaded.
I noticed that some features have been added recently, but there's not yet a DEB package for it (probably it's considered unstable).
After I downloaded the source to compile I noticed there was a debian folder there... so I thought:
Why not add PCSXR to my PPA? - And that's what I did.
Latest 327223 is there (for i386/amd64/lpia). There are packages for both Karmic and Jaunty.
