[Frogger progress]

I allready did that but since the playfield is only 256 pixel (like the original frogger) I needed to "waste" some cycles for the "fake" broder (and also waste one color).

 

Hmm... For those border sprites make sure you are using WM=0 and direct sprites. That will have least number of bytes per pixel, thus the least number of MARIA cycles. (Although you may need to use a 5 byte header if you are changing write modes.)

 

Also, use direct mode instead of indirect mode.

Right but I would have to rewrite too much of my code I better find another way.

It shouldn't be too bad, but I know what you mean. I need to rip apart the DL building code for SpaceWar! 7800 and I'm not looking forward to the experience.

One thing that gives me some headache is that I am running out of maria cycles.

Ahh, one half of the 7800 curse - not enough MARIA cycles to do everything. (The other half is not enough CPU cycles, after MARIA has stolen most of them, to do everything. :-) )

 

One thing you may want to consider (if you're not doing it already) is using a DLI to change the background color and just use that for the background. Also, use direct mode instead of indirect mode.

[7800 stuff in progress]

My paddle proof of concept was very simple - it displayed onscreen two decimal values- one for each paddle. The plan is to use that code as a base to display four values (X & Y for each player).

 

Additionally, trackballs, like paddles, have to be read multiple times per frame. (Although I should be able to get away with using a DLI.)

[7800 Graphics Modes]

Whatever it is, it doesn't look like it affects palettes 0 & 4.

[7800 stuff in progress]

It's not so much a demo as a test program. In theory it will have all 6 graphics modes on-screen at once in regular bit patterns. Unfortunately, my first attempt last night just put garbage on the screen.

 

However, it does appear that Kangaroo Mode impacts more than the documentation suggests.

 

But yes, I will post the final version for others to have a look at. (Also the only way I can get PAL tested.)
