i totally agree with member Lordpro; its an excellent emulator but it should be perfect when the options (start+white)load position (start+black) save postion should be solved. (game saves) this option never worked perfectly with mamedox but if someone could make it better...? on some games it works whithout any problem but on several games `screen freezes` and you need to reboot the xbox. on metalslug 3 and metalslug 5 (load/save is crashing), on mslug 1, 2, 4 load/save position works great.
