If it's not against the rules, I can post the file here or send it to you via some other channel? Note, it doesn't have extra levels, it's just that the existent levels are much longer and don't end at the usual points. That said, you probably have the same version. Just try it and you'll see. It's probably as long as Amiga version. Levels are almost double in length.

It's from Remember group. And now that I paid some attention, it seems it's some sort of cartridge version. From the intro: "Welcome to Remember release 273. Rick Dangerous was taken from "Power Play" cartridge -something- in December 2001...." Strange thing is it's so unknown. Even Gamebase64 version is regular and doesn't have this one. Granted, I didn't update it in years, maybe it does nowadays. Anyway, I was dumbfounded when discovered the game doesn't end at usual points I was used to in my childhood.

OK peeps. May I ask you a question. Am I the only one that plays RD version for C64 that has all the screens? Yes, approx. twice as long version, just as on Amiga? I searched the internet to find out about it, and nobody seems to be aware of it. I obtained it somehow, somewhere, years ago and to be honest, I always like the shorter version better. It has better flow, and the levels are simply some of the best level designs in the history of gaming. The longer is just more of the same, it turns into a grind exactly in that place some people call "breaking point" between 8-bit and 16-bit versions.
