i updated to the latest Retroarch 1.20 and LB 13.18. I'm not sure what changed but i cant seem to launch my NEO-GEO set with final burn alpha 2012 core . 
 
	I went to the retroarch settings and double checked the settings they still look correct 
 
	SNK NEO GEO MVS core= fbalpha2012_libretro, default emulator  checked , extract roms = unchecked 
 
	SNK NEO GEO AES core= fbalpha2012_libretro, default emulator  checked , extract roms = unchecked 
 
	 
 
	I went and installed a separate retroarch with only the fbalpha2012_libreto.dll core and it works , but i didnt want to have 2 separate emulators t runnning .
 
	If any one has the time i could use some advise on what to check to get this corrected
