Holy shit totally fucking gasped in horror at chapter 1, check out why and see if you agree with me.
yes spoilers, about 2 hours into it:
The game is pretty sweet so far.
I had a hard time getting it to work on my EZFlash V 3-in-1 slot 2 device. See the way playing Mother 3 works on that device is that it uses NOR mode because the PSRAM mode isn't big enough to handle the mighty 32 mb of Mother 3. Problem with NOR mode is that it takes a while to copy it over. That isn't terrible but what it does is basically store the entire GBA rom in there. Just to make sure Mother 3 would work on the device I had tried it out before the patch came out. So later I kept trying to run the patched version and it kept popping up in Japanese. It still had the unpatched version stuck inside the device and it thought the patched version I was trying to run from my Cyclo DS was the same rom (it technically is as far as the device is concerned) so it didn't bother transferring it over. So I had to start an application (GBA ExpLoader) and clear the NOR and transfer the patched version of Mother 3 over.
One more tip is that once you've put Mother 3 on a EZFlash V 3-in-1 you have to keep using that cartridge to load your save data. I put Mother 3 on another EZFlash V 3-in-1 I had and it couldn't load the save data without corrupting the data. I doubt this would affect many people but it's just one of the things I found out and should the situation come up that two people live in the same place they need to keep their EZFlash V 3-in-1 paired to their Cyclo DS or whatever slot 1 cartridge they use or they forfeit all their precious progress in the game.
This thing is sticky, and I don't like it. I don't appreciate it.
