I tried to compile mame2009 for ps3 and vita, but it get errors while compiling.
For ps3 this one
For vita this other one
Anyway I used an old version of vitasdk, so i’ll try to compile it again once i updated the toolchain on my end.
I have only renamed makefile (there’re two makefiles) and i added a vita target to compile for vita platform. If you like it, i can do a pr your repo. https://github.com/Ezio-PS/mame2009-libretro
PS: I can finally thank you to fix ngp core, the fix you did for WiiU worked very good for ps3 too, since WiiU and ps3 are both big endian machines, so i guess everything you fix for Wiiu target can be used/or easily ported to ps3 platform to benefit your work on more platforms.
