After a brief trial downloading those games, it seems that Sonic 1 GG and SMS are similar enough to be tracked on the same board much the same way that Sonic Adventure (DC) and SADX (GC) are.
There may be some differences between the two, mainly in the field of view, and some levels may be advantageous to play on a specific system (or in this case simply a specific form, as the same emulator is capable of handling both).
One other thing I noticed, though, is that in addition to getting the usual 1-up with the 100th ring, your ring total actually goes back down to 0, meaning that technically no more than 99 rings in any level can be recorded. How should this be reflected?
