Haven't used my Acekard 2i in a while, need some assistance.

it works on them just fine, as long as the firmware is compatible. if you buy a new system there is a chance it will be updated to the point that you can not boot the acekard. if you are only into ds games and homebrew then i would highly recommend the dsi xl. that larger screen makes all the difference. i'm pretty sure you will have no trouble tracking down a system with a lower firmware. it is something any seller can check for you in under 30 seconds.

According to the Acekard website, 4.3.0-10 is the latest firmware version they have fixed.

If you can get a 3DS that has firmware 4.3 or below, you will be fine. I also hope your Acekard2i has HW81 - there was a revision to the hardware and HW44 models do not work on the later 3DS firmwares.

DSI 1.44 is the cutoff for DSi firmware working with the Acekard2i.

In this case, the two things I would recommend are

a) keep your Acekard2i and purchase another DSLite or DS phat (this can run you $70+)

b) Purchase a DSi or 3DS and buy the Supercard DSTwo (around $40) or R4i Gold 3DS (R4 is about $20 cheaper than Supercard, but the Supercard is a more powerful card allowing you to emulate more like GBA and SNES games better and smoother than the R4i could.)

Good luck!
