Ok I've understand why the display looks weird. You test it on a megadrive with TMSS and the TMSS leave the scroll size to 64x64 and I didn't reset it on my demo. Anyway, I've just taggued the lib to version 0.1. You can download it on the homepage of the lib ( http://www.megadrive.org ) along with ...

The picture isn't very good. It looks fine on the TV - it was the fact that you showed two pads and two other "things" that I found weird, not the image. :? Ok, thanks for clarify this :) Another odd thing was I only found info on Team Player, not the EA4Play. The great Charles have written some do...

Yeah cause the MULTI mode (aka the original Team Player mode) isn't supported. Only the "EXTRA" mode is (aka EA4WAY compatibility)
For the display I look like it's in double interlace mode but it shouldn't be ... weird.

I don't see problem with the display on my TV.
And it's say that your team player is a EA4WAY because it's on the "EXTRA" mode.
I'm looking at the "MULTI" mode of the team player.

I've just add support of 6 buttons joysticks.

Regarding the ea4way, is it supposed to work with a 6 buttons joystick plugged in ?

The GPL2 licence does not take effect on the output of a program, this means that any code compiled by gcc isn't GPL. I don't know about BEX but I doubt that the output is protected by any licence. If you use some code made by someone else it depends on the licence of the code itself. But even if it...

But the thing is your's it two "high-level" for me it's more like an game engine as you got some sprites routines, fading routines etc ... But, I'm not agai...

Sorry to triple posting like that :)

Two little things :
1) I haven't test the lib on hardware for now.
2) The license of the lib is 2 clause BSD and it will stay like that.
No GPL licensed code will be imported (in fact I'll prefer to not have imported code at all)

And happy new year in advance :)

Is gcc-4 really needed ?
I don't think it improved the m68k support.

I've just updated the binutils to 2.20.
I'm currently documenting the function with doxygen, when I'm done I'll post my lib and the toolchain makefile here.

Sega DevKit

Hello all, I've started a mini devkit for the megadrive in asm (gnu asm) but all the function are intend to be call from C (as I'm more fluent in C :P). The goal is to have a full devkit for the megadrive/megacd and 32X. I have a gnu/bsd compatible makefile to install all the toolchain (binutils 2.1...
