MegaMan 10 OST arranged in real Nintendo [short blog]// Submitted @ 3:38 PM on 04.10.2010
Mathew Valente (TSSF) has been sequencing game music for quite a while. His skills have really improved with time, culminating in this ambitious and totally righteous project of restoring the MegaMan 10 soundtrack to native NES format.
You can download this here and read more about the process in his readme. In addition to the NSF, he has provided the source file for those wishing to listen to and watch the sequencing in FamiTracker.
