MAMEWorld Forums - Programming - Re: Mame scaling help

Hi R. Belmont,thanks for reply

Sadly, new Mame builds, are too slow in some games, but 105 works great. Anyways, same happen in latest mame, then the question is valid, i tested latest build of mame, and same problem

I dont understand very well what do you say, now im not use cleanstretch or aspect ratio, just ddraw without any hardware stretching, and the image DONT fill the screen in width

For example, if I use a resolution of 640x240

if the game is 320x224, it FILL the screen, scale to 640x224
if the game is 320x240 it FILL the screen, scale to 640x240
if the game is 256x240 DON´T fill the screen, scale to 512x240 and leave black bars on left/right

If i use a resolution of 512x240 then...

if the game is 256x240 it FILL the screen, scale to 512x240
if the game is 320x240 DON´T fill the screen, dont scale , and remains 1:1 320x240

For what I see, mame scale only in integer ratio, but not more than 3x, then 256x240 > 512x240 or 768x240, and 320x224>640x224>960x224

Thats why I create a 1280x256 resolution, because this cover 256x and 320x in integer ratio, but sadly mame, dont scale to fill the 1280 resolution, it stop, like I say, in 3x (768x for 256 and 960x for 320)

What I want to do, is scale width TO fill 1280 (4x for 320 5x for 256), and height just leave in 1x. In this case, I dont need to do many custom INI for each game, because 1280x256 covers A LOTof games (most games I like are 256x224/240/256 or 320x224/240/256 )

Hope you can understand what I tried to explain

Thanks
