I have a Nintendo DS with a DSOne Flash Card with EOS installed on it.
Before the software update, it works completely fine.
Just recently, I've managed to find an software update. However, after the update - It seems to be stuck in an endless loading screen.
There's several things that were suggested to do to find the problem, such as using the troubleshooter (holding LT and RT while the DS is starting), but it is to avail.
In case, here's the results:
Test Flash
flash id ok!
flash ok!
Test sd card
sd ok! no find test file.
Test Psram
psram ok!
Now SuperCard DS Version:
English Ver1.01
Test finished.
Is there something else that I'm missing? Am I using the wrong EOS version for my card? Is there any other update steps I missed?
