I bought the dual screen add on (I had surgery and was stuck in bed, sue me, figured it was low-risk/high-reward) and the piece of shit finally came in. If there are any games any anon would like to test, add it to the list and I'll get to it at some point tonight. On the list:
>DS: infinite space, etrians, spectral force genesis (no-budget stylus-controlled dragon force clone)
>3DS: etrians, whatever the fuck else it was an etrian/soul hackers machine for me in retrospect the DS was way better
