Whats so good about Cyclods?
Well, I tell you the truth: Nothing.
everything is good in almost every flashcart.
I will clasify flashcarts(using microsd) in this order cyclods-scdsone-r4/m3 simply-ezflash V.
-R4/m3 is the best if you take into consideration its cheapness. Full rom compatibility(including download play) but no microsdhc, no wii compatiblity, no ingame guide support, no homebrew soft reset, no full touch screen menu support and bad quality microsd slot spring. Clunky case.
-cyclo ds evolution is the best flashcarts out there. It has got everything working(d/p, wii conection,sdhc, ingame menu...), it only misses two features of supercard, realtime game guide and homebrew soft reset.
-Supercard ds one is the best value in my opinion. It's a bit more expensive than r4/m3 and a bit cheaper than cyclods. But it's got game guide and homebrew soft reset over r4/m3 simply and it misses microsdhc suport and wii connection that cyclods has.
-Ezflash V Is a good cart, very good if you can't get a good microsd because you can play even problematic games with hybrid mode. It's cheap and from a well known team.
