Oh and just out of curiosity, how does Stella determine what bank-switching scheme is in use? I don't need a lengthy explanation. Something along the lines of.. - it uses a database - or it checks which address lines or memory locations are being used. Or even, "it's just magic!"
It mostly searches the ROMs for certain load and store instructions associated with bankswitching hotspots, along with a simple heuristic based on file size.

Looks cool. About what frame rate does it run at?

I'm listed twice on the Gyruss list, in positions 5 and 20.

Galaxian - 17,120
EDIT: I'm annoyed that Gyruss doesn't have any cooldown period for the fire button after losing a game. I broke a hundred fifty thousand points, but because I was firing away at an enemy formation when I died and didn't immediately stop, I started a new game and lost the chance to photograph the score. #[email protected]%$!!

That sounds good.. And I also think its good as is. I think just having something up there is good for now because I still need to add other things. I still need to add a little menu to select one or two players and maybe some other flair.
Of course. Better to get the functional stuff out of the way first.

I wonder if the logo might not be more visually imposing if you did it in a two-line kernel, to make the pixels more square like in your Excel screenshot.
But the one-line resolution looks good too in any case.

Here's what I've come up with for the title screen 48 pixel image. How's it look?
Snazzy.

A 2600 Jr Rev. A. I didn't think to check the board revision when I opened it a few weeks ago. I could take a look again tomorrow.
Oh yeah, I figure I should ask this beforehand (to possibly save any unnecessary work): is the revision number usually on the top or bottom of the board?Never mind.

It'll probably work, especially since that game is only 4K.

What console model and preferably PCB revision do you have?

ZackAttack and I have come up with a test ROM to clarify which bits are not getting stuffed. If you see something other than this please post a photo:
What a mess.

I thought Stella was open source and absolutely free for any manufacturer to modify and use. Is that not correct?
Stella is free software, yes, but it's distributed under the terms of the GNU GPL version 2, a so-called "copyleft" license. If you modify copylefted software and then distribute your modified version, you're legally required to provide the source for your modifications, which some people and companies don't like for a variety of reasons.
(I'm not making a moral judgement of the GPL here. I quite like it, actually.)

I think I'm fatigued on this game.
I did find out, though, that Millipede has a screensaver, so that's cool.

For some reason I can't edit my last post, but if you're interested, this file has the checks and heuristics I mentioned.
