[How to extract SFPack files on a Mac OS X]

Why not send the pack to a PC user with SFPack and ask them to send you back the SF2s?

[WIP: Command and Conquer - Act On Instinct]

I realise this a first post in the deep end, but:

Overall, I liked it. You'll probably need to work in a bit more extrapolation of your own before submitting though; there isn't much here that deviates from the original.

The sound you used for the pad melody at 1:01 didn't quite jive with me. It felt a bit cliche, and I'm not too sure if it fits in with the grungy bass. But they never play together, so I could be wrong.

The production all sounds decent, at least on my cheap little headphones.

Like I said, it's not bad! I love the source and look forward to hearing future drafts!
