just thought i'd add my two cents.
all CLEAN games work for me that i have tested, and i've tested about 500 (seriously, i did. wasn't too tough with a 4GB SD Card). even trace memory, contra 4, and mk. the only problem with "testing" games is that i do not play them through 100%, so there is really never a way of knowing if a game that boots fine will play through fine, but i assume they will.
yes, there will be updates, has the neoflash team ever let us down? that's a little tongue in cheek, as anyone who has bought neo products knows, but i am still confident we will see updates. also, check out YSMENU if you want a nice alternative that uses folders and has some extra slot-2 device support for GBA. i use it and prefer it to the DSTT menu. since YSMENU is built upon the official menu, i'm not sure that we'll see it supporting patched or hacked roms in the near future, assuming the DSTT team doesn't care to support them (and from everything i gather and a lack of answers from dr. neo, i don't think they plan on a fix for it).
i freakin love my DSTT and the ONLY drawback thus far is the lack of ability to play non-clean roms. other than that it is the best card for the money.
last, it's ridiculous to say it has 100% compatibility and go and change it in the review because what happens when a new game comes out that doesn't work? should they go change the review again? and then a new update comes out that fixes it and they have to go change the review yet again? i went a couple years only using my MK3, and a few years before that using an MK2, so i guess i can settle with 99% compatibility.
p.s. thanks for the review, it's what convinced me to buy it.
