I have a couple of questions, currently using a emunand 9.2 sysnand 10.3 ndsxl, i was wondering what cart (r4/ds-two/acekard/other) is best for my system. Also is it safer to boot into emunand and then run a ds cart? Thirdly I have an old r4 card for my original ds from like 2008 would this work...
