Well, I expected a worse performance, but then again, modern tools have more space to manoeuvre and utilize more sound chip power. Even FM synth in Doom 32X Resurrection sounds better then the vast majority of Genesis/32X releases. It's also interesting if the project can import and play this soundtrack.
At first, I didn't believe it was recorded on a real Genesis until I had heard the piano in Jade Empire track. Yeah, now I believe it's Genesis :)
