[Feature Request] Having a similar feature to the Mesen NES emulator in terms of replacing graphics & audio in games

[Gagert]

As seen in this video, it's now possible to replace both graphics & audio in NES games because of a newer feature in the NES emulator Mesen.

Having a similar feature in a Sega Mega Drive/Genesis emulator could allow for especially multi-platform games such as Aladdin & The Lion King to have all the best features in terms of graphic & audio on the Genesis version. In Aladdin, the Genesis versions gameplay is butter smooth compared to its screen tearing counterpart on MS-DOS, but the soundtrack in the Genesis version however sounds thin and low quality compared to the orchestrating-sounding soundtrack in the MS-DOS version.

With the Genesis version of The Lion King, the screen resolution is naturally higher on this version compared to the SNES one (wider res on Genesis), but because of the more limited color palette in the Genesis version there's more dithering present here to compromise for the lack of colors. The audio quality is also better in the SNES version, a more detailed comparison can be found on this site at Retro-Sanctuary.

Even though the graphics in some Sega Genesis games may have passed the test of times in many cases, it would be nice if it was possible to for instance change out parts of the soundtrack for rearranged compositions of the same music-track (the option menu in Sonic Spinball comes to mind, me don't like).
