hm. I would recommend trying it again. The DKC trilogy does have anti piracy bootscreen if it detects latency with the pin connector, but that shouldn't happen when you plug it directly into the Supaboy without the use of any other adapter. My copy of all three games works fine with the Supaboy. it's possible you have a later revision, but I still haven't heard of any such issues. Do you own any other Super Famiclones? If your copy of DKC2 doesn't work on your Supaboy it shouldn't work on any other clones either.
