Can an image on a PSone screen be doubled?

If you're making a portable you probably need something to watch it on. (Unless you want to guess what's happening in the game, but I wouldn't advise that) Anyway, this forum is your "Hacking a pocket TV/screen" one-stop solution. Share your experiences and knowledge here.

Can an image on a PSone screen be doubled?

Post by bacteria »

Problem - RGB modded an Amstrad GX4000, looks a lot better than composite (and pretty good actually); however in both modes, have the same problem - image only takes up half of the screen.

Image looks nice in real life, photo sucks, but illustrates the issue:

How can I make it double size to fill the screen? Ideas please?

If not, ideas on a 5" screen with a low resolution and RGB input but decent quality?? Playing on such a small screen area isn't an option!

Update:

Interesting, turns out the game I tried first was the worst one! Unlike other platforms, it looks like this one doesn't scale games to fit the screen at all. It also has graphic resolutions of about 160 x 200 to 620 x 200.

Roughly speaking, the following games seem to take about the following amount of screen space:

Batman - 50%
World of sports (bad game anyway) - 65%
Barbarian 2 - 70%
Burnin' Rubber -80%
Switch Blade - 85%
Pang - 85%
Navy Seals - 85%

I can live with that.

Barbarian 2, Burnin' Rubber, Switch Blade, Pang, Navy Seals are the games I really like - the others not so fussed. About 70% of the screen is ok; 80%+ is fine, frankly; you end up with equivalent of about a 4 - 4.5" screen image (not measured it, guess).

The games I mention are quite acceptable in size, so will have to accept "as is".

So yes, each game seems to have a different resolution and the PSone screen doesn't scale them to fit the full screen, unless someone knows how! Might be an option in the game itself to scale up, but doubt it.

RGB looks nice and crisp.
