So I've literally been reading up/researching cards all day yesterday and I'm down to only a few I'd consider buying. This happens to be one. I like all of the features the Supercard DSTWO offers but I have quite a few concerns I'm hoping somebody could help me with. From what I've heard/learned this card seems to have a few problems and I'd like to gauge responses from people that have had this card a while and use it regularly. (and hopefully take care of their electronics so carelessness isn't a factor) 1) Battery charge length reduced by approximately 40% while this card is powered on regardless of what it's doing. (Due to the on-board CPU most likely) 2) The plastic casing seems to have a design flaw with only one screw oddly placed on one corner of the cartridge. (vulnerable to exposure to dust/dirt etc?) 3) Some of the GBA roms either lag or dont play at all. (unsure about the other system emulations) 4) Various plug-in problems such as audio lag during video playback. 5) There doesn't seem to be much technical support for this card. 6) Random features ceasing to work or struggling to work properly after only a few weeks. Another card I'm interested in is AceKard 2.1. I've been meaning to buy a flash card for about 4 years now and whichever I purchase would be my first card. I have an original Nintendo DS and mainly like the GBA/MAME/various other emulators in addition to DS games this card offers. Honestly though I'd be fine with an Acekard 2.1 and a slot 2 card for GBA emulation if it came down to it. The impression the Supercard DSTWO places on me is that it's a quick-burn, short life card and if that's the case I'd rather not spend 35-40 dollars on it if it can't handle regular use. (I'm kinda a hardcore gamer.) If I'm wrong though, please let me know how your Supercard DSTWO has worked for you and any recommendations on the best store to purchase one. My sources I used to get info are this website, the DSTWO's website and forums, and some youtube reviews.
