Fighting Roller / Roller Aces is all about holding forward to jet down the racetrack and avoiding all the dang obstacles you can. All tracks are littered with all sorts of crap: Speed bumps, rocks, cylindrical columns, and gaping pits.
Move along lines, erasing them as you go, to collect flashing or spinning items. If you collide with one of the yellow dots that are moving around erasing lines or if you end up at a dead end with nowhere to go, you lose a life. You cannot go back, only forward.
Mr. Do!'s scenario is a roller coaster, and the object is to reach the top. As the cars (and eventually other objects) speed around the track, you must escape by using a super speed button, or by climbing up small ladders scattered about the track. Two icons at the end of the level range from cakes to EXTRA letters or diamonds change upon collecting cherries at the top of each letter. The game is timed, and the timer ticks faster when the super speed button is depressed.
The player controls an alchemist who has been summoned to defeat an evil warlock. The game is set inside the warlock's castle, with the game's primary objective being finding four pieces of a magic scroll. This allows the alchemist to use the "Spell of Destruction" to defeat the warlock.
The alchemist can transform into a golden eagle, requiring the use of spell energy. Transforming between the two is essential to completing the game. The alchemist can hurl lightning bolts and other spells, but the eagle form is required to negotiate steep hills or drops. The alchemist can only carry one item at a time and must consume food to keep stamina levels up. Movement, bumping into objects, or transforming depletes the character's stamina. Fighting monsters also reduces the character's stamina, although this can be mitigated by carrying an axe or sword.
The Black Onyx is a role-playing game developed by Bullet Proof Software. It was released, among other consoles and computers, for the SG-1000 in 1987. It was the last SG-1000 game to be released in card form, and the last to be published by Sega, but it is currently unknown as to whether it was the last SG-1000 game. MSX and PC-8801 versions had been released in 1983 and 1984, respectively, meaning this version is unusually late.
The game was followed by The Black Onyx II: Search For The Fire Crystal, which saw its original MSX release in 1984.
It is a semi-real-time adventure game developed in 1983. It was released by MIA under the title “ONION HOUSE”, although it was originally known during development as “Circumference.” The game features a distinctive system that combines the command-based adventure game format popular at the time with real-time action elements. It is characterized by a high level of difficulty and complex puzzles, and has been regarded as a title that divided opinions since its release. The game was distributed on cassette tape. Its original retail price was 980 yen. The supported platform is the PC-6001.
