Help with update!

Hey,Are any other software OS' etc... compatible with the EDGE cartridge? What I mean is, COULD I put different software on a Micro USB and put that in the same cartridge for use.The problem is the update to 1.4.3E and the latest supported version by them is 1.4.2 (I think).If yes, links and SIMPLE instructions would be greatly appreciated.

As far as I am aware, there are no 3rd party firmwares that work on the edge flashcart.

Hi there, thanks for replying, another question if you don't mind;Is there no way the card can run at all now?
On the same device that is.

if there is no 1.4.3 update then no it won't work anymore. A third party firmware would not help if there even was one.
