Sorry im just a bit confused.. I have a DSTT and im looking for a SLOT-2 Cart to do GBA stuff+RAM+RUM So my question is... Whats the newest EZ-FLASH 3 in 1 expansion cart version? I've seen a "4" and a "V" im a little confused if theres a difference. Also , which is better? Ewin or EZ-Flash for GBA+RAM? Thanks.
