Yes, North of germany...

Yes, North of germany...

I am guessing you live in Poland then! So much great stuff comes out of Jack Tramiel's homeland!

I know somebody who publishes homebrew games on cartridge in the UK who could probably help if you are interested.

No, i'm really from Germany, not from Poland  " title="Roll Eyes" />
My town "Bad Oeynhausen" is 100 km south from Hanover,  the town of the CeBit Fair & Expo 2000.

Yes, sounds good. How would such a cart release be produced?

I just wrote an article for Retro Gamer magazine on one of the most famous German software companies Thalion  :1:

Yes very true actually  :109:

RGCD do anything really, they just started publishing Atari Jaguar games for example.

But i do not have a clue how to read data from a Module, as the game will NEVER fit into 64 KB.
I do know how to support the extra-RAM to load data from disk only once...

...but how would this be handled by a module ?!?

With a cartridge you can load data whenever you need to and very quickly, so each level could be 64k if you wanted. Space Harrier on the XL/XE is 1MB in size! I am not a programmer, so I don't know the exact technical detail but I am sure I you or I can find somebody to help you.

That's definitly worth thinking about...

I am just working on the last feature of the game engine: The moving enemies.

My sprite multiplexer seems capable of drawing one enemy per line without flickering.
As the CPU time (while drawing the screen layout) is really occupied with alternating fonts and changing color registers i only have CPU-time to multiplex one pair of player.

(The display list interrupt is already turned off, as saving the registers takes too long.)

I now have the choice, if two enemies were in the same line:
a) Draw each enemy only every second frame (enemies will flicker)
b) Show the odd lines of enemy 1 and the straight lines of enemy 2 every frame.

The picture gives an example of b) on line 7

what do you think?

Thanks for your feedback

I think in this case the flicker would be better, it worked well in Space Harrier. That technique makes the sprites really hard to make out.

Just testet: It runs on modul on PAl and NTSC Ataris!
(even on my NTSC Atari 400 with 48KB)  :-)
