I was hoping to play the ds version in pc & mobile.
Unfortunately, I can't compare the effort of translating a ROM to getting an emulator to work, because they are very different types of hacks.
What I *can* do is assure you that you will be able to play the DS version on emulators on your phone and computer (for the ones we've tested it all seems to work, at least). We haven't done a test with a ROM cart in a couple of months, but back when we were regularly testing that everything seemed to work too.
You should be covered for options on how/where to play the patched ROM.
