Tom recently informed us that he has updated his mod of emericaska8r's SuperMarioBros.Portable v0.1 (SMBPv0.1). Tom's take, which basically replaces Mario with Luigi, is now on version 4, and hopefully this one took care of the problems that you have been ranting about in the comments section.

He mentions that he got complaints about several issues with regards to the game, one of which is the problem with sound effects. He claims that this update already took care of that problem. From the looks of it, this recent release is definitely better compared to the first time that we saw it. But then again, that's just my opinion.
