My R4 spring is ruined and now i cant insert my Micro SD card anymore. So im gonna buy a new card and im thinking of either an Acekard 2(ver 2.1) or SCDS1(ver 3.0) So can you tell me the good and bad sides of each of those flashcarts? Also how is the build quality of each card and do they fit perfectly into the ds slot(by perfect i mean like a game cart)? Since both are them are spring loaded like the R4 how good is the spring, does it break fast like the r4? Does these cards firmware fix games with piracy prevention methods(like DQV),or do i need to patch them myself like with R4?
