Well, at least being able to output RLE for static backgrounds would be nice. Of course, you could always do better by using something like RNC on a "normal" background image.

Well, SEGA CD uses the Genesis VDP as it is... So, nothing different.
I didn't read all about 32x graphics, but the only interesting feature I see would only be export RLE encoded, as you people have already said. At least, at my point of view. If you want me to implement it, I need to know how 32x implements RLE conding...

Here's the plugin for Windows. Sorry my delay... I use Linux and I had to figure out how to compile from here to Windows. Please report any bugs and suggestions.

This plugin allows you to prepare the image to megadrive format and save it.
On menu Filters appears an option Misc > Megadrive adjust: this will turn your image 16-bit colors (asks you if want to use a previously made palette or a new one from image) and crop your image to 8x8, 16x16 or 32x32 multiple size. Ctrl-Z works step-by-step (undo crop, undo colormap changes, etc.). If you think that's better undo all at once, please let me know.

In order to export it, save with ".smdi" extension. A dialog will appear asking some options before really save it.

It's impossible to load it back by now, and maybe never

Again, please report any bugs and suggestions. New feature requests as well

"This application has failed to start because libgdk-win32-2.0-0.dll was not found. Re-installing the application may fix this problem."

Edit: Wait, didn't read that it was a GIMP plugin. My bad.

Well, half half.. The segacd have a rendering hardware... which render picture from RAM to RAM... This rendering hardware have several little stamping modes, one use a 2048*2048 map made of 32*32 (or 16*16, i don't remember) pixel tiles.

But.. haha

who gonna use the segacd rendering hardware? Maybe in a contest?

I'm working on a demo using it. When it's done, I'll be sure to post it here.

Anywho, I can't test the plugin as I use linux. Any chance of a linux version of the plugin getting posted?

oooops, it's been 3 weeks i tried to add one sprite to steff devkit without success
Fonzie tried to help me, but since he couldn't edit steff functions to handle char tiles, he gave up... always use asm to pad/store tiles he said

why no genesis image tools ouputs 32bit array for tiles... because, they always output unsigned char arrays... and the unsigned char is never padded to int inside the rom... so it sux
and how can i add a "*.s" with stef's compilator?

Thanks a lot for your help it's hard for a noob to dev in MD

bastien,

do you want a 32-bit array output?

I think I'll put this option on my GIMP plugin? Did anybody test it?

As I said, I would, but I need a linux plugin.

What's the last version of Gimp that runs under Win98SE and can that plug in be used with that version ?

Here you are, the last GTK+ version for Windows 98. I don't know if you must use this old version of GIMP, though.

http://gimp-win.sourceforge.net/old.html

As soon as I come to home, I'll compile my plugin for you, but I can't test it...

Please, add me on MSN Messeger or ICQ network, if you use it. I don't want to release the source code before it be "(dumb) bug free".

I added your ICQ to my buddy list, and put my ICQ number in my profile.

TmEE co.(TM),

please test it.

Win98 version plugin (GTK+ 2.4)

New Windows (NT, XP, Vista) version plugin (GTK+ 2.6)

Sorry, I uninstalled Gimp... didn't like it (or I couldn't find it suitable for pixel art)... I still prefer MS-Paint (you can all call me crazy now

)... but I'll test that plugin anyway.

EDIT : Tested it, and works OK if the source image is 4-bit, otherwise you'll have "can't convert to 16-color image" error. And you should add such ASM saving format too that uses DC.Ls :

Code: Select all

 DC.L   $01234567   ; one line from a tile

So, no way to add .s files (in a VERY simple way) to a Stef devkit project?
I ask that because I'm pretty embarrassed about explaining the things to some peoples when the difficulty is just to add few sprites to the rom (storing tiles in C program, as unpadded unsigned char, is just silly to me) ^^

Thx for the help, I suspect Bastien will give up soon.
