I had another question. Does playing a Gameboy game on the Super Gameboy count as emulation or regular hardware?
It's hardware, but some games have specific rules for the US Super Gameboy or outright ban it, as it runs faster than the real hardware due to some peculiarities with timing. The Super Gameboy 2 (Japan only, but can be swapped into a Super Gameboy 1 shell), doesn't have this but runs a tiny bit slower I believe.
-SGB and SGB2 do in fact count for hardware. -Many boards (but not all) will accept SGB1 times; but since it runs at consistently faster, you will have to convert them to the proper time first. (Shoutouts to Nudua for his converter: http://nudua.com/convert) -It is encouraged to use an SGB2 if possible though, as it runs at the proper clock speed.
Game boy games make for some great speedruns, so have fun in exploring the library!
@Legs is right, apparently SGB2 is pretty much perfect! Now I want one... And here's a good article comparing the features of the two: https://www.retrorgb.com/supergameboy.html
The SGB2 and GBP (Running stock software, or GBi) are the main hardware standards we use in the GB community. There are technically video out mods for DMGs, but they are rarely seem in running.
I paid about 40 CAD for my SGB2, but I've noticed the price creep up lately.
The GBP has the added benefit of playing GBC and GBA games, as well as not having to deal with SGB enhanced games (which suffer from slight loadtime issues, because of the extra data associated); but the SGB2 has the benefit of working fine out of the box (The GBP suffers from some picture and input lag issues on the stock software, hence the use of GBi)
I think this may be -slightly- out of date, but you can read more about GB Speedrunning, as well as the technical issues with it here: http://www.gbrunners.com/game-boy-speedrunning-explained
