Errors

It's okay, you don't have to be sorry since you didn't know. You're doing a good thing helping out and most of what were spotted were mistakes that got fixed. The only other mistake that I've spotted is regarding the arcade Donkey Kong Jr. In America its Donkey Kong Junior while in Japan its Donkey Kong Jr. You were on the right lines since you corrected the NES version but didn't know about the title change between Japan and the US for the arcade so you changed it to the US one but forgot to keep the Japanese name too. It's something that MAME documents but not the Nintendo sites, not a known thing but a bit more obscure.

Sometimes researching is hard work since a game could be obscure or rare, it might have multiple names (e.g. on the 360 there's a racing game that is called Crash Time II in Europe, Alarm for Cobra 11: Burning Wheels in Germany and Autobahn Polizei in the US), it could be spelt in different ways (usually romanization of Japanese/Chinese/Korean games), it might be a common game but forgot a detail or a hard to find version and there are mistakes online too. Some games are just that hard to find any info at all, that also applies to what you are ripping too regarding names, where they come from, even the genre of the game. In some cases, its not even documented at all and have to do it yourself.

Even though Sonic Retro is a reliable site when it comes to the Sonic stuff and do know what they are talking about, even they can make mistakes or in this case weren't updated since the Korean Sonic 2 is an obscure release like anything in Korean gaming that isn't on the PC. Until a few years ago, no one knew that it existed.
