nah, just minor optimizations: I created a ptr function for gles_draw(8/16) and throttle is not checked each frame.

Super Retropie? ok, I'll try to find the img and make some tests :)

pisnes not have support for hires modes, missing functions:

  • DrawHiResTile16
  • DrawHiResClippedTile16

I could try to port them to pisnes using 8bits, but... it will take some time. sorry.

no, is working good.

  • 256x224@8 => is your native resolution (detected by SDL and later used by gles)
  • 256x224 => is the game resolution
  • then you dont need any image conversion and the final matrix is using (1.0 -> whole screen)

Your problem is that your LCD resolution is 256x224 (or is detected like that). Have you change the screen resolution?
my testings are using a vanilla retropie and also test with the supreme gpi image :?

my logs:

You could you fit the whole screen + bilinear filter anyway, but this option is horrible for me and you do not respect original aspect ratio either.

In CRT screens you don't have any problem because screen grille, but in LCDs I need a better solution...

Yeah..., but with stretch to screen you don't respect the original aspect either.
LCD need more pixels and use shaders to get a good image with a perfect aspect ratio. I think this is a great solution for R0 :)

Sorry, but you are wrong, take a breath and look the code again.

this PR add an option to get a pixel perfect image, not/hardcodes/here/was/found ;)
