thanks for reply, the memory works in others games such snk vs capcom 2 , marvel vs capcom 2 and sf3 TE, but frogger 2 in all forum says it works perfect but the memory card is not, the game starts very nicely but after the picture with the crocodile says VMU not detected you need at least 7 blocks free , i like to know is a bug from chankast or the vms browser because if all says in other forums that fragger 2 works perfect is not like that, if you can´t save your progress the game is incredible boring.
