Hi guys im fairly new to Mala, I have it set up running MAME, ATARI2600, and SEGA Emulators perfectly thanks to UncleT’s instructions. 
BUT i seem to be having trouble running my Nintendo roms, I am running Zsnes and have everything in their correct folders, but when choosing the Nintendo ROM. Zsnes seems to open up in its own little window (not full screen). 
Then if I try to get out of zsnes and back into mala I press the Esc key, but it only exits out of the ROM, leaving the pink and purple main screen for Zsnes, ? ? Is this correct, 

 im not sure what I have done wrong
Please please please HELP !  

Thanks
