Replacing the original SPC soundtrack is none other than the complete soundtrack of covers by Polish musician Krzysztof Slowikowski taken from his album Mega Man 7 Guitar Playthrough, adding very welcome wailing electric guitars to the action.
You can find the patch and instructions on how to use it from the project page here. There is even a version of the patch for the original Japanese release - Rockman 7: Shukumei no Taiketsu - if you prefer.
Would a Super Nintendo Playstation version of Mega Man 7 sound something like this? We can but imagine. Feel free to drop in the comments below if you enjoy this new take on the old game or if you still prefer the purity of the original SPC700 chip efforts by Yuko Takehara, Toshihiko Horiyama and Makoto Tomozawa.
