I few weeks ago, I realized that these two games were not originally released for the console, but where made years later as reproductions. According to the DP guide, it was thanks to a company called ResQsoft that re-released them. I tried searching through Google and I did find the website, but unfortunately the company does not make them anymore.
How hard is it to find these games now? I've never seen them on Ebay.
Sure, Sentinel was (if I am not mistaken) released in the UK, but how hard is to find the NTSC reproduction?
Also, did these games have their own box and manual? From ResQsoft, Sentinel seemed to come in box, but that is all I can gather.
Any information regarding the games, author, company...or any relevant info about it will be appreciated.
