I have 0.9.10 and I encountered a problem, so I decided to use the earlier 0.9.9 version because I wouldn't have a problem. I copied my platinum file and states just to be safe, and pasted them in the battery and state folders. However, when I opened the rom I got the new game menu and couldn't access my progress. The files each had the same name. Is it possible to transfer a file to an older version? I know you can transfer from an older to a newer, but can you do it the other way around? Also just to note, I'm using NTEVO roms, which only edit the evolution settings of pokemon that evolve from trades and stuff: http://pokemonntevoroms.blogspot.com/
