@Addison said in Retroachievements:
What emulator and version of it are you using?
I use the default RetroPie 4 SNES emulator for raspi2: lr-snes9x-next.
About the ROM version: I'm not at home now, but they usually talk about it in retroachievements.org, in the specific game achievements list page. ;-)
edit: in my raspi1 I use lr-armsnes.
