That's really interesting, I don't know much about the evercades and it's actually pretty cool to learn that they use Blastem. Is that actually a binary that can be used on other Arm devices?
+1 for that 7-31 firmware making my Jr. work with my Pocket. (Class 10 Gigastone MicroSD.) And afterward I was also able to use nitro2k01's sgb enabler.
