AVGA and Arkanoid: whats a good resolution to pick?

<< < (3/7) > >>

Well I think what you aren't understanding is that arcade monitors don't auto-adjust like a computer monitor would.  Almost all of your horizontal games are gonna show up great without adjustment because they use the same resolution (or multiples of the same resolution) vertical games, on the other hand use an inverse resolution.   

Monkeying around with it some more should get you closer to a nice full screen, but you aren't going to get it perfect without either using hw stretch or adjusting the settings. 

btw your running 640x480 in those pics, which is why it's so small.  It's too high a res.

No, I just took a picture so you could see the dead space. If I print a screenshot in Mame it won't have it. That's actually 512x384. I understand that there's going to be some space since the resolution isn't exact, but that's a lot of space.

Can you use the monitor controls to center arkanoid at the desired resolution? 

I don't have a fancy pants monitor like the Betson 27" Multi-sync, but with my arcade monitor, I have to manually adjust the monitor controls each time the resolution changes.  Fortunately, the monitor controls are easilty accessible under my control panel.  In a real (legal) arcade, you'd have to switch boards to switch resolutions, so you'd install the new board, adjust the monitor and call it a day until the next time you installed a new game board in the cabinet.

The dead space is being generated by mame, not because the monitor adjustment. I'm just going to pick a bigger resolution and turn on stretching. You see, it's my lady's favorite game, and if we can play it I might as well not have the arcade cabinet at all :) I just wanted to figure out why I couldn't get it to display properly.

Silver:
When you say 'dead-space' I presume you mean below/above the image (can't tell from the oversized pics).

For vertical games, the best you can do with a horizontal monitor is have no 'dead-space' above and below the image, but you will definately get lots of dead-space either side of the image. (Obvious, but just want to check we are aiming for the same thing)

Arkanoid seems to generate a 256x224 screen. So I don't understand why it's cropping when you run 256x256.

Although I think there is a whole (pixel) aspect ratio issue we are overlooking - 256x256 sounds square, but is obviously not as we are running on a 4:3 screen. So although we should be able to display a 256x224 image (rotated) on a horizontal 256x256 screen, it may still look incorrect, and if you have aspect ratio settings on, mame may be correcting for this.

This is where my brain tends to melt calculating aspects....
