That headache would be yours...
Never used Hyperspin, but if the rom files have the correct ending, it should just be a matter of packing & renaming. I'd just try with one in a standalone revision of CO.
But period. I would head over to back-ups & dl the COMassive.
As the art for the roms would be missing as well, when "ported" to CO.
Just keep an eye on your ratio...
If you already have the massive & the games you talk about are missing, check whether they are supported in the list of supported games, which is found in CO's readme folder.
If so maybe packs would be the better option, too.
btw: welcome aboard, aainge!
