I use the r4cce for my code purposes but for some reason it won't work with certain games. I know newer games are compatible because I've got codes for Dragon quest IX, however some games simply will not appear no matter what I do. Some examples are Pokemon SS, Monster Rancher DS, phantasy star 0, and mario kart. None of these games will show a cheat option even though I've made sure the game numbers were correct with the r4cce. Any idea on what I could be doing wrong?
