I'm going to be recording and releasing an album soon and wanted to know if there's a significant difference in the sounds of a recording exported from bGB and a recording made from a DMG plugged into a line-in port on a PC.
If you wreck shit on a gameboy to the point where DMG's can't handle anything you do anymore like me, or use any sort of crazy dubstep shit without going into GBC mode, then I would highly recommend against using it.
It's a great application, not for recording imho
I think the biggest advantage of using BGB is being able to quickly export each channel separately for mixing without added noise. Also more reliable.
