Great game, congratulations!

Understood. I did have BASIC on.

Thanx

It is working now after resetting the settings I wonder what was messing up things...

nope

It might be my settings then. I don't see any interlace and the lower part of the screen shows different.

I was looking at some pictures and this one(http://atari.fandal.cz/detail.php?files_id=5371) is not showing correctly. I am using Altirra 2.30 test 10

I have started to code it for a thomson machine I have created a blog for my retro codin' stuff but it is empty still.

It seems a good candidate for a port.

On their website you can load the games+sources. I have ported some of their games to the c64.

The Coco line of computers The Dragon 32/64 The French 8 bit computers from Thomson

Thank you for being so generous with your knowledge. Be sure I will bug you if I get stuck Today I spent sometime reading your tutorials here and other documents on the VDP. Then I copied your code(the randomize routines come specially handy I don't know if I am going to use them as they are but they are a starting point ) from this thread and adapted it to my needs. And at the moment I have graphics mode 2 working + sprites. Now it's time to get dirty with 'real' TMS9900 assembly as I need to start putting the game together(I am coding the same game on the 6502 and 6809, so I only need to translate what I already have and then add what else might be needed).

Awesome tutorials Matthew. Thanks.

Thanks Lee. Indeed it will be interesting coding for a processor without stack logic

Thank you guys, Yesterday I was reading 'beginning-assembly-language-for-the-ti-home-computer-second-edition' and it answered many questions I had about directives and 9900 asm Anyone know how the TMS7020 compares to the 9900? Ta.
