Now photoshop a 6-switch instead of the globe. Job done.

Great show! Thanks to everybody who participated. After just three years, the AHA have IMO become the major event of Atari homebrewing, just like the Oscars are for movies. And with almost as many categories. BTW: I like calling them "Stella". And before the show started, we had a lot ideas for even more categories.

I just tried the website with 94.7.129.241 (Belfast) and it is reported as GB.

Yes, your demo had a bug that initially misled me. But nevertheless the timing calculation in Stella still has a flaw. I wrote my own, simple test program now.

Stella also has a problem. The timing is not 100% precise here. We are working at it. For now, make sure that there are at least 2 full scanlines between the write and the first read.

OK, got it working. Now I am going to analyze why Stella needs two full WSYNCs

I cannot assemble bBasic asm code, it is not DASM compatible ("unknown Mnemonic RETURN"). So you have to post the binaries. Or all files needed to assemble. Warning: Unable to open '2600basic.h' Warning: Unable to open '2600basic_variable_redefs.h' Warning: Unable to open '4scores.asm' The one ROM your posted (with two WSYNCs) behaves like gaugau described.

Sounds like your required delay is larger than what John found out. Interesting.

And as soon as you do three WSYNCs everything is fine?

Your first WSYNC is not a full WSYNC. It can be anything between 3 and 76 cycles. So you need at least two WSYNCs. Can you describe the choppyness you experience with two WSYNCs? Or post a bin?

I cannot see "Frame0", but I can only see one full WSYNC after setting VBLANK in your code.

Stella has a wait time of 1 scanline (76 cycles) implemented. We found this number to be safe after some experimenting. Not sure why you need multiple scanlines here.

You got it almost right, currently it is $1B, $1F, $0B, $0E, $1E, $0B, $1C, $13. But your pattern is correct (and matches the other two pattern), so we will fix that. The UI bug is known and will be fixed soon. Alternatively you can use the commandline (see doc).

3) is definitely not feasible and the other two only with compromises. I am sure Atari would have done what you suggest if it would have been feasible.

Since we have no clear cut code pattern (yet?), the auto-detection in Stella looks for certain strings in the ROM: full QuadTari: 'QUADTARI' left port only QuadTari: 'QUADL' right port only QuadTari: 'QUADR'

It should work if the ROM is auto-detected. Unfortunately the entry in the manual controller selection is missing, this will be fixed soon.

I don't know this website and where they got their information from. Probably they are just outdated.

Robot City is (mostly) a port of an Odyssey 2 prototype.

What do you mean? Stella supports the QuadTari (except for the selection bug in the Game setting dialog).

Thanks! The kernel originates from a 1K game compo. When space is so tight, you have to find efficient solutions. BTW: Actually the helicopter is done by a missile, so it is also mixing colors of two tanks.

ToR is 8K.

We hope too. But progress is very slow.

Though the total votes are already ~50% larger than last year, it looks like we a not reaching the number of votes per category this year. VOTE!

Looks great! How did the screen height change? From to to?
