Original Resolution / Aspect for each game
-
So, it’s a strange thing. When I set a resolution of 320x224 the game fits the screen and plays smooth but looks terrible.. When I set 640x448 the game slows down sometimes like my graphics card is keek.
Wtf
It’s as if RetroPie can’t handle Outrun! -
@retrocraze nothing is worse than a keek graphics card. I hate when that happens.
What emulator are you using? What ROM? What computer? There are so many variables.

Lol!
I’m using a Raspberry Pi3 with RetroPie.
The rom I am trying to get playing smoothly is Sega Outrun on Mame.

@retrocraze you still gotta be more specific. There are nine versions of MAME you could be using.

I’m using a Raspberry Pi3 with RetroPie.Lol indeed.
Anyway, here, try this.

I believe is Mame lr-mame2003. lol

That really interesting!
SO from what I read, that can run as a port on emulation station? I just need to get those versions of Outrun for it to work.

@caver01 @dankcushions I found this thread searching for correct aspect ratios for a few games. Generally speaking - I'm following the rule above that the default (core provided) aspect ratio is correct in lr-mame2003.
However, I noticed in my setup that Mat Mania, when run on lr-mame2003, it appears too narrow, so I used a .cfg file to change it from 'core provided' to 1:1 and to me, that looks correct (and running the same rom on lr-mame2000 appears to set it at 1:1 as the 'core provided' ratio without manual config).
@caver01 said in Original Resolution / Aspect for each game:
What he is saying is that if you leave well enough alone and don't add any extra configurations, lr-mame2003 will scale the game to fill your display using whatever aspect ratio is correct for the given ROM. Crucially, this might NOT be proportional scaling because the game image was often stretched to fill original arcade cabinet CRT displays (4:3). AND it is rarely integer scaling because using integer magnification would prevent the stretching needed in one direction or the other to reproduce the original aspect ratio. Besides, integers rarely multiply out to exactly fit your display's resolution. BUT it will look correct, or at least it should match the way it looked in the arcade.
I was also curious about Mortal Kombat (which seems too narrow to me at 'core provided' ratio). But if I'm reading the above (and understanding it) correctly, as long as I use the 'core provided' aspect ratio in lr-mame2003, it should match the way it looked in the arcade. Is it too narrow looking because I'm not using an actual arcade screen that "stretched" the image?

no - the point is that core provide will do all the relevant stretching and/or squeezing that the actual arcade screen would have done. for example, mk had a standard 4:3 CRT so the aspect ratio provided by the core should be the same. mat mania is a 3:4 game so that should be 3:4 via core provide.

I just want it to be the games corrext ratio and potentially smaller on my screen with more black borders.
If you're using libretro emulators (e.g. lr-mame 2003 or lr-mame2010) you can edit the game (rom) specific cfg file to set the size and position of actual "game area" on your screen.
Check this file as example. That game "Spiders", plays correctly only in mame 2010 but that emulator has wrong default aspect ratio. That cfg fixes the problem. -
@udb23 FYI the aspect ratio issues in mame2010 have been fixed, if you update it via souce. 2003 always worked properly in this regard.

@dankcushions Great, thanks for the update !
Yes 2003 works fine out of the box. Using 2010 only for those ROMs that do not work correctly in 2003 (or FBA). -
@dankcushions Got it. Thanks - appreciate the clarification. I think I was simply mistaken on what the proper AR should look like for those games. Although I think as a personal preference I like Mat Mania slightly wider (1:1).
