opcode Posted August 13, 2003 Share Posted August 13, 2003 Hi there! I see some contestants don’t understand why are they getting strange outputs from bmp2pp. Well, the CV video isn't bitmapped, so don't hope it would be like MSPaint just with a limited palette. In order to create a good CV splash screen you need to understand how the CV video works first. I created two simple rules: 1) Vertically there isn't any restriction, aside the resolution and color palette. 2) Horizontally, just take any multiple of 8 coordinate(for example 24); it and the remaining 7 pixels on right will allow just two different colors. Again, it is a CV limitation, not a problem with bmp2pp. If you create a screen and it violates the above rules (mainly #2) then your resulting screen with bmp2pp will be changed... Hope it helps...

Thomas Jentzsch Posted August 13, 2003 Share Posted August 13, 2003 Hm, looks like many artists over here do not like to follow technical restrictions that limit their artistical freedom. Or are you just unable to follow those restrictions? Prove me wrong! Quote Link to comment Share on other sites More sharing options...
krisjohn Posted August 14, 2003 Share Posted August 14, 2003 Or are you just unable to follow those restrictions? Or maybe no-one told us about them. This is the first I've heard of this limit of two colours per eight pixel segment. Unfortunately I don't have time to work on any more screens, or fixing my two exisiting submissions.

colecoprog Posted August 14, 2003 Share Posted August 14, 2003 Thanks, opcode and Thomas for mentioning these restrictions. I had failed to mention these for hopes of people having the easiest ability to create entries. Plus, I am by no means a veteran programmer of the Coleco Vision. (I am still hacking at it) To clarify what opcode mentioned about the restrictions Consider the following portion of a entry converted to a powerpaint file at the bottom of this reply. This file is being viewed with the CVPAINT program. Notice that each row of eight pixels only contains two colors, however each column can have eight different colors (Just said in different words from opcode) : That is why if you (contestants) want total accuracy in your design use the CVPAINT program which puts these constraints on your design right away. However, I will accept any design and I am looking for design talent and idea originality more than anything else. I can fix up an entry I like to look as good as possible. That is why I will accept BMP, GIF, PNG, and PP files as entries Have fun and Good Luck!!! Quote Link to comment Share on other sites More sharing options...
colecoprog Posted August 14, 2003 Share Posted August 14, 2003 I goofed and said 8 colors in a column. It should be 15 different colors throughout a column, as many as you want Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted August 15, 2003 Share Posted August 15, 2003 sorry for posting here ubt i am interested in coding coleco? maybe you can tell me an assembler who can write rom images? some documentation? hve Quote Link to comment Share on other sites More sharing options...
colecoprog Posted August 15, 2003 Share Posted August 15, 2003 Well it is nice to see more people interested in coding for Coleco Vision. There are a series of tools I use to code in C for the Coleco Vision. They were made by Daniel Bienvenu. Here are two links where you can find them. http://www.geocities.com/newcoleco/framesen.html http://www.gooddealgames.com/articles/Cole...rogramming.html Have fun and good luck! Why don't you enter too. Quote Link to comment Share on other sites More sharing options...
