Pokemon HGSS working with M3 slot-2 devices

Sorry for starting another topic, but the official is closed and there's an abundance of related ones, which mostly die anyway.

Anyway, if you have an old slot-2 SD/MiniSD M3 device (like the Pro or Lite series), you can get the new Pokemon to work with only an ARM7 swap. I used this one. Settings for the GM: 1xDMA, Force R/W, Trim Rom, Soft Reset. Works flawlessly. Dunno about the 3rd badge, because I haven't got there yet, but up to the 2nd one I haven't had even one freeze.

 

Similar results were posted about the old Supercard Lite slot 2. I'll add this to the main topic.
