Dragon's Curse a 1989 TurboGrafx-16/PC Engine video game released in Japan as Adventure Island
The arcade game was later ported to the Sega Mega Drive, Sega Master System, TurboGrafx-CD (Japan only), ZX Spectrum (Europe only), Amstrad CPC (Europe only), Commodore 64, Amiga, Sharp X68000 (Japan only) and Atari ST, with minor graphics differences, depending on the system, and some changes in the gameplay, mainly in the bonus stages.
Within the next few years, it would also be ported to the NEC PC-9801, MSX 2, Sharp X68000, Mega Drive, Super Famicom, and TurboGrafx-16; a Dragon Slayer: The Legend of Heroes Barcode Battler card set was also released by Epoch Co. in 1992.
One example of this is in the game Castlevania: Rondo of Blood, which was written for the PC Engine CD-ROM which does not support multiple background layers.
The duo also had a PC Engine video game called "Kato-chan and Ken-chan" (translated and censored for a Western TurboGrafx-16 release as J.J. & Jeff) based on their antics, filled with toilet humor, and featuring them as the game's playable characters.
He said that gameplay and backgrounds remain varied and that "the fire rod weapon is especially fun to wield", but he noted that the things that keep the game from being better than Zelda were repetitive and frustrating dungeon exploring, boring boss battles, long passwords (for those who do not own a TurboGrafx-CD), and several "head-scratching moments" which include references to Judaism and Islam as well as quotes from Star Wars.
These include most of the classic 8-bit systems (such as the Nintendo Entertainment System, the original Game Boy, and the TurboGrafx-16).
