Hi everyone,
So I have been configuring all the retro systems that I can with Retroarch. I really love RA. So I am aware that the atari systems work with mame_libreto core and it works well. I dont want to use MESS anymore. Also I am using the same core for the neo geo CD, philips-CDi and other related systems (as some guides posted in this forum) and they work well too… so far so good.
But when I play any atari rom and then run a neo geo CD rom, it wont work anymore. RA crashes on start and I have to delete the CFG file to reset the core and to make it work again with neo geo CD.
So I have my atari systems with MESS again to avoid this :frowning 
Does anyone have experience this already? I am using this for my hyperspin. Thanks
