I usually play on FCEUX on PC, but going on holiday w/ my Macbook. I'd like to play a bit of AISSON. Does anyone know how to play AISSON in OpenEmu?

Hey there,

To play AISSON on OpenEMU, first open your SMB rom, then make sure the core is on FCEUX. Then in the floating menu, select "Cheats" -> "Add cheat", then just type in the cheat code (AISSON), click "Enable now" then click "Add cheat".

Hope that works, and enjoy your holiday!

As far as I'm aware, this works for all SMB codes (see here: http://www.zekeragsdale.com/mario/ ), but it may require a console reset to apply.
