Excellent! I',ve been there when I was 13, and the place was forever impressed in my mind. Here's the original picture:

The remaining two are really difficult if not impossible, so I'll reveal them: S is one of the ancient entrances to the city of St. Andrews, Scotland (a tribute to the very first foreign city where I went when I was 13 - and I had a VIC then
); and V is the Kalahari Desert, where unfortunately I've never been.
Yesterday night, I showed IOSGA to a friend of mine, who is quite keen on old computers (he actually assembled the FE3 for me), but I realized he was not impressed by the graphics screens at all. In particular, he couldn't recognise some of the subjects, such as the swampman, or the logmen on the pier. I had to explain them, and I felt like one of those modern art experts explaining the meaning of abstract paintings
.
I wonder if I had to choose sharper and simpler images, and/or use "monochrome" combinations such as blue+light blue.

The multi-colour resolution of 80x192 pixels puts a tight limit to small details, even more because the aspect ratio of the pixels is so non-square, and the halftoning adds even more "noise" in a 2x4 pixel pattern.orion70 wrote:[...]In particular, he couldn't recognise some of the subjects, such as the swampman, or the logmen on the pier.

In my experiments with PGM IMPORT the results often improved, when I masked out unimportant details in the background before converting the picture.
Since most of the pictures were scanned in from the book, it might have been feasible to convert them to B/W lineart, without dither. That would have allowed for 160x192 pixels.
Yes and next days you will see resultsorion70 wrote:Thanks and welcome back! Been busy lately?

No i've not identified itHope you'll identify the column in G screen - it's not so far away from you, another region and another sea though...

Thank you ral-clan. I'm planning to play IOSGA on a real VIC with the FE3 one of these nights. Has anyone already done this?ral-clan wrote:Another amazing achievement!

I recently spent a Saturday afternoon transferring games from the "Official releases for 2008, 2009 2010, etc" threads to D64, and finally on floppy.ral-clan wrote:Thank you ral-clan. I'm planning to play IOSGA on a real VIC with the FE3 one of these nights. Has anyone already done this?
I've played Island of Secrets Graphic Adventure on the real hardware and it works great.

Excellent!. When I re-coded the program for coulored 22 columns, I need to change the parser routine, then I tested the program 4 or 5 times, but only in vice emulator, also, as you know, the mistakes only appear if another people test the program.Ghislain wrote:I've played Island of Secrets Graphic Adventure on the real hardware and it works great.
