A few games I've never found are actually a serie of three adventure games published by Hal Renko (Kasper Boon) . See the links for more information on each game. The games were published in books and could be typed in, but also were published on tapes for the persons who didn't wanted to type the very long listing. They were written for several platforms.The Antagonists
I own the Dutch C64 book and a working copy of the Dutch ZX-Spectrum version and C64 version of the game. The English version however I've never been able to locate. The Secret of Arendarvon Castle
I own the Dutch C64 book and the English C64 book. I own a working copy of the Dutch and German version for the C64. The listing in the English book contains some bugs which makes it impossible to play. An erratum for the book was released but alas this didn'nt solve all the problems. The version published on tape should work allright though, but I've never managed to find a copy.The Seventh generation
I never seen the book or the game. Any info would be nice.
