That's a standard config for the MegaDrive, gives Master System compatibility and controls sound for the MD itself.
I believe the Master cartridge adapter idles the 68000 and passes control to the 4 Mhz Z80, but apparently some games require a Master controller, not sure which.The megadrive also was completely back-compatible with the Master System, which had a Z80 CPU. The master system adapters were pretty much just a straight through for the the original cartridges.
Should be doable, just scrape the trace back a way from the break to ensure no shorting to the other tracks.
I have to be honest, I love Space Harrier, and the Master System is not the best place to play it, for me it's the Saturn, and I prefer that version over the Dreamcast version.
I really hope you can get that trace fixed and it up and running though.
