The first game by Jeon Jaeyun and his team was a simple Tetris clone. Or maybe not so simple, as it is designed as a competetive 2-player game with some advanced rules and special blocks.

Both players chose from a cast of eight characters (apparently, Michael Jackson was the epitome of popular in 1990's Korea, too), who then occupy the lower part of the screen to harrass each other with special moves each time a player does something special, like deleting multiple rows at a time. While it is possible to make the opponent lose by clogging the whole play field, there is a strict time limit and most rounds will be decided by the status of the characters' life bars. How those are reduced isn't always transparent, though, which can lead to much frustration.

Little is known about BriXian, although it does look a lot like a Puzznic clone. Actually, there is no solid proof yet that it was indeed developed by Jeil Computer, but the fact that Mijin published it makes this very likely, as all other known Mijin games came from either Jeil or later Semicom.

Jeil Computer's contribution to the ever popular single screen arcade action platformer genre. Just like Bub & Bob from Bubble Bobble and all their other colleagues in similar games, the martial artist Hanbit and the heavily armed Narae clear out level after level by destroying all enemies on screen, of course not without the aid of countless powerups left over by the defeated.

Every few stages awaits a boss, where the different abilities of the two characters come in handy. The whole game is conceived as a co-op experience, but not always are the mechanics thought out well. The female character isn't even able to beat the first stage on her own for lack of a low attack, unless she has the luck of an enemy dropping the flame thrower for her.

There's also a PC version, which plays out quite differently and almost feels like a beta version of the arcade game. It's also brutally hard, as it basically forces players to 1cc the game with the lack of credits.

Metal Saver (PC)

Already before their Arcade team left the company, Jeil Computer started to restructure and focus on online games. They announced a lot of games all at once, but none can be confirmed to have been finished.

The only games ever shown in magazines were Tank Survival (title screen only) and Super Funny Ball, which looks suspicously like Semicom's first baseball game in the arcades. Only mentioned in name were Final Tetris II, Action Pee & Gity (apparently an online version of the Family Production game), Lost World, Je-1 Gonghwaguk ("First Republic"), the Janggi-based board game Mureung Doweon and 3D Survival.

A Pang clone for two players. The goal is to deplete the opponent's energy by shooting the balls over to their side, while avoiding getting hit oneself. There are four characters to chose from, all bringing with them a unique spriteset for the balls.

One of Semicom's main legs~ during their early years was a series of baseball games. Fonts and screen composition in the first entry appear very similar to Super Funny Ball, announced originally by Jeil Computer, so it seems likely the development team took the project with them when they left their former company and produced this as the final version of that game.

Wonder League Star in the next year took a more realistic visual style, yet it clinged~ to crazy stuff like super deformed penguins running around the playfield. More games were released with a yearly schedule until 1997, each time with a slightly changed stile to make it worth the update

A puzzle game similar to Magical Drop.

Taking famous franchises and copy them almost exactly with just a different graphical layout has always been a very common practice in the Korean arcade business. The three Cookie & Bibi games of course are derivates of Puzzle Bobble / Bust a Move, replacing Bub and Bob with a duo of squirrels.

Though not an official part of the series, the laterR&B seems to follow the exact same template.

R&B

Hyper Pacman is — of course — a Pac-Man remake with breakable walls, a laser helmet, x-ray goggles and more crazy stuff.

The game received an update with Twinkle , but apparently, Semicom has gotten a bit more careful concerning copyright issues, thus dropping the Pacman name.

Twinkle II

Billiards.

Toppy & Rappy

Toppy & Rappy can be seen as a sucessor in spirit to Metal Saver, although it seems inferior to the two years older game in many ways. Not only does it run in a lower resolution, but the art style is very inconsistent between sprites and backgrounds as well.

Once again one male and one female character are used as protagonists, but this time they have equal abilities and only differ in their looks. Instead of grabbing powerups directly, the two gather money by defeating enemies, which is used to buy weapons and ammunition in a shop between stages.

A fighting game with eight super deformed characters. The 3-button control scheme is more typical for 3D fighters like Virtua Fighter. Cute, but not very deep and rather stiff to play.

In 1998 Semicom released an update called Cute Fighter, with new stages and characters for a total of 12.
