Hi all,

I request your help because i would like to add this image into a simple megadrive demo with gendev:

http://sega4ever.power-heberg.com/tutod ... 20misa.bmp

I use gendev (not the newest) and in my other demo i just use one palette for one image with Genitile and now for a better result i want to use 31 color + transparency ( maybe 2 plane for an highest result ? ) but i have no idea when i can make it

maybe someone can help me ?

Thanks

My GFX converter can do it, but it needs you to create a 256 color image with first 32 colors in use, and 16th index (when counting from zero) must be unused on the image, otherwise you lose a color...

ok so this can works ?:

EDIT: i have try with your convert but i use windows 7 and it seems QB4.5 don't work.
can you give me the converted result or another way to do it ?

I can give you the tile files (direct INCBIN) and palette files (DC.L in them). Also, 16th when counting from zero is the 17th color

(fix the BMP, I can then do the conversion).

GB1 is colors 0...15
GB2 is colors 16...31
and TXT is the palette values

???
thanks but what is GB1 file format and how i include it in my code ?
i think you will give me an *.s format .

but thanks for the conversion

its a straight binary file of the tiles, ready to be INCBINed into the program... but if you're doing something in C you need some program that will convert the data into some textual stuff...

thanks you very much but it seems your conversion are wrong;
lot of color have the same value ...

but here is my pal result in demo :

do you think i can have a better result ?

Posted: **Tue Dec 07, 2010 7:30 am**

This is because your original image was not correctly quantisized to MD color values, and the converter cannot know which values to create...

MD palette values calculated so are Round(ColorValue / 36), remember that the RGB channel step is 36 on MD.

long time ago, i did a tool which splits your picture into two separeted picture (layer 1 & layer 2). Then you just have to convert them separetly with genitile.

but you'll need to convert your bmp to pcx

I want to try this out, but when I give it a pcx, it seems to just crash. How does the palette need to be laid out? I have colors 0 and 16 as transparent.

Posted: **Tue Dec 07, 2010 1:48 pm**

is the pcx is 256 cols ?

Your layout is correct
