Hi all.
 
I'm doing the Colecovision version of Lunar Leeper, a game announced by Sierra Online and only published for C64, Atari 8-bit and Apple ][.
 
So far I've solved all the technical hurdles of it, mainly the scrolling engine and fitting all the required graphics for it. Also I've drawn all the required graphics.
 
Apr/01/2019 lunar valley visuals working.
 
Apr/03/2019 tunnel visuals working.

Apr/14/2019 game completed now in testing. :grin:
 
*Start of original joke of Apr/01/2019*
Last night I was testing games with my CoolCV emulator in search of things that aren't emulated properly, I had a set of backup CD with ROMs from old times (probably made in 2005).

One of these CD turned up to be interesting because it was a FTP directory that I downloaded in year 2000, it was simply named COLECO. I remember I downloaded many ROM files from FTP but didn't took note of site names.

It was a pretty complete recopilation of the Colecovision games, but one game that brought my attention was LUNAR.ROM dated Nov/04/1996, probably dumped by someone.

 
Interestingly I had tested all games before but this one didn't caught my attention because it was incomplete and I forget altogether about it, but this time (and after years of experience collecting Colecovision games) I recognized a prototype game!!! Lunar Leeper by Sierra Online.
 
It's an incomplete game, but nice to see something like this after so many years! :)
 
Enjoy it!
 
*End of joke*

Do you recall the ftp server from which this file came? Just curious.

LOL - nice one.  The description in your YouTube video gives the game away though  :)

Haha I expected no one to read the video description :dunce:

So for now my personal prank mark is 32 minutes before discovery. :)

Nice one Nano!

As soon as I saw Lunar Leeper, I knew it was an April Fools prank considering that was my guess for the CollectorVision proto that is yet to be revealed.

Glad you like it :)

I think I found interesting the game so I had to do something.

Then I should choose a more obscure prototype for next year :grin:

It will be interesting to see how you pull off the scrolling cavern sequence of the game. :)

Very smooth scrolling.  Even the scrolling text on the bottom of the title screen is smooth scrolling. Very cool!!!
