I thought I'd post to see if anyone was interested in a Korean compilation cart known as Super Game 138.
You can see images here comparing it to Super Game 270:
People seem to seek Super Game 270 just because its listed on Guardiana Kingdom and I think too many people take that site for fact that those are the only Korean exclusives. Super Game 138 is certainly of the same quality of 270, though it is not listed. Check out the incomplete list below:
Anyways I think I have a buyer for the one pictured above, but I may have the opportunity to get my hands on another copy in the same condition if anyone is interested.
I believe most of the games on the compilation are SMS games, though I have not explored them all, and with the older games I am not as familiar which games were SMS games and which ones were MSX games. Aside from the standard fare SMS games like Rambo, Fantasy Zone, Ghost House, My Hero, etc. there is at least one Korea-only SMS game.
The first game you can select from the menu (game 1 of 138) is titled 초원의 까치 but once you load the game up you see is the game 개구장이 까치 (Gaegujangi Ggachi).
Gaegujangi Ggachi is a platformer released in Korea in 1993 from the company HI-COM. The name of the game has been translated to mean "Ggachi, a naughty boy." It has also been translated as Mischevious Magpie. While the word 까치 (Gachi) means magpie (a bird) in Korea, in this case 까치 is used for the character's name. It is a popular character from the comic books of 이현세 (Hyeon-se Lee). Kkachi is famous for his first TV animation "떠돌이 까치(Tteodori Kkachi - Kkachi the wanderer, 1987)", based on the comic book of same name. It is also a first Korean TV-only animation (The very first Korean animation was a movie "홍길동(Hong Gil-dong)" in 1967.)
The game has been described as being similar to Alex Kidd in Miracle World. The game is actually quite a bit of fun, though like the majority of SMS games, simple, but unforgiving. I was able to find a great link with TONS of screen shots of the game, as well as images of the original box art, etc. You can view it here:
Here is a video of the game I found on youtube: http://www.youtube.com/watch?v=bGHuTeH3780
I have tested this game and it is working without issue. I cleaned the contacts on the game and it boots up without issue or blowing on the cartridge. It was actually very difficult to find a working copy of this game, but finally I've got one and was pleased to find Gaegujangi Ggachi on it. The menu for the game displays 16 games at a time, but you need to scroll down through the list to reach the higher numbers. On the back of the box it shows 8 Groups, but in the actual menu there are no Groups to select, just the massive game list. The shape of the cartridge is the same as a Japanese game. It will play on a Japanese Mega Drive/Genesis, but to play it on a US console you will need a passthrough cartridge like a Game Genie. I am not sure about what is needed for PAL systems.
