In the mean time, I've ordered a bunch of stuff from Play-Asia to complement my newest console purchase.
My GBA games library is rather sparse, and is occupied by the excellent Made in Wario (Warioware Twisted) and Mother 3 (which is unplayable without a guide).
Digidrive (a bit Generations title) and Donkey Kong: King of Swing are on their way to remedy this situation.
I also purchased a third party Screen Protector Seal for the GBM. No point in gettting the GBM's very nice display all scratched up, therefore prevention is better than the cure.
