I just got the most recent nightly version of Retroarch wii and noticed the size of the .7z file was bigger. Then the surprise, looks they change many things on the cores. Official Stella(atari) core! Official Mame 2000 core! The Final Burn cores are now called "fbalpha2012" They have 4 Snes cores: snes9x, snes9x2005, snes9x2005_plus, snes9x2010. The catsfc cores don't exist anymore. I don't tested yet, but I will tet them now.
