aah, mame2010 didn’t work as libretro have just been changing stuff around I see (renamed the makefile). I need to update the script.

I assume desmume is broken due to upstream changes also – I’ll need to check further. You got unlucky with your timing sorry.

mame2010 isn’t particularly useful really on the rpi, unless there is a specific older game it supports that earlier versions don’t. It is significantly slower than earlier versions (as mame is built for accuracy not performance)
