It’s Streets of Rage 1-3. It’s not emulated by a bunch of gibbons, so it doesn’t have any controller lag. You can choose your region so you can play the PROPER version of SoR3. It has a nice selection menu, and high res scans of all the cartridge box/manual art.

Music emulation is still off though – Not by much, but it’s still off.

…Like if you wander into a room and get hit by an eggy fart that somebody left 20 minutes earlier.

But by all means get it if you want a 50th copy of Streets of Rage. You never know, if it sells, Sega may think about making a Streets of Rage 4! Because we know THAT can’t POSSIBLY be a bad thing!
