Looking for a flashcart for 1.4.5u?

Hello Folks.
Long time no posts:)So i recently was able to get a nintendo dsi black from a friend for $30 and it was updated to 1.4.5u.
I like to research everything about something before i buy it and i discovered that acekard 2i does not support 1.4.5u.Are there any REALLY good flashcarts that support dsi 1.4.5u?I already looked at the stickied topic. No help.Thanks

I just saw the Supercard DSTwo. It might be the winner.Is it compatible with 1.4.5u? I don't know if i can trust the sticky because it is somewhat outdated.
And can it REALLY play GBA games from slot 1? I would LOVE that.

GBA games on a DSTWO is emulation using the CPU and RAM built into the flashcart. results can vary by game but my understanding is it generally works very well

But does the DSTwo have support for DSI 1.4.5u?The GBA emulation thing is really just a bonus. I'm really just looking for a flashcart that works with 1.4.5u DSi.

Well my Acekard 2i sounds like it had a decent run. Right now looking to get a 3ds to play Monster Hunter with my friends, figured I could take my old Acekard for my dsi for some more games, but this sorta means probably ordering this DSTWO instead.
