Im new and have 3 questions

1) Do all Acekards work with micro sdhc card?2) What cool stuff can i put on a Acekard besides DS games and music3) Thanks in advance and is this the right board for my topic?

All acekards work with SDHC.Various homebrew exist that can do stuff. Browse the internet (pretty crappy though). Read comics/manga. Read books, etc.
Acekard works well with the EZFlash 3 in 1 and can load and play GBA games if you have one.
You can run emulators for earlier systems like the NES, SNES, Sega Genesis, Gameboy and Gamboy Color. They all have varying degrees of compatibility though.

Tririth covered almost everything, but he forgot that you can watch movies.

thank but does anyone have a link for a NES,Snes, and Sega Geninsis emulator? I dont wanna download anything bad onto my new AceKard (I get in a few days)

Sorry couldn't find one, I'll keep an eye out.I can confirm that the two links I gave work, as I run both of those emulators on my AK2i as well.

;D Thank you, im not really big on nes games anyway.

Glad I could help. :)
