In case other people haven't seen this before, Lordus already has certain games running sound (those that don't need the Z80), this video is from over a month ago though, so it has gotten better since then.

Searched but unfortunately couldn't find a topic about this =(. I just got my R4 and UPS tells me that the microSD should be here tomorrow. Will I be able to just take the .nds file and run it or do I have to patch it with DLDI?
