I have an NDS lite and recently put the rom megaman zero collection on my r4 and the graphics are very strange on the game. I tried other sites, pick up other files and the same error continues. My questions: 1) I need the expansion of memory to play this game? 2) This error happens to anyone else? please do not say it's because of the R4, it is cloned and can not play anything because it's the only game where this happens.
