Missing NTSC resolutions

[lauren7ino]

Hi
I believe this is the same UAE4ARM used in ArkOS (Anbernic RG353M with 640x480)

Request: Can you please add the NTSC resolutions to the resolutions list?

Documentation shows that these resolutions are supported:
640x270/320x240/320x256/320x262/640x240/640x256/640x262/640x270/768x270

Unfortunately 90% of the Amiga games I have use NTSC resolution (320x200), which means they are shrunk vertically with a black border on the bottom. 320x240 is the closest resolution offered.

Can you please include the NTSC resolutions on the list, so that the game fills the 480p screen?
320x200 / 640x200 / etc.

Thank you and keep up the good work!

There isn't any 320x200 ntsc resolution. It always is 320x240. 200 pixels and 60hz would be too low freq for ntsc. And actually is 262 lines for ntsc (262x60 = 15.7 khz) hidden in borders. You just requesting a "crop video above xxx pixels" feature.

Thank you for your answer.

I only wanted to take advantage of the full screen of an Anbernic rg353m 640*480 res, with a little stretch.
In fact in the offered 240px res, games are a bit flatten out.

I'm an IT, not an electronics engineer, and I sincerely I don't know why Amiga NTSC games came in 200 px resolutions instead of 240 px.
(maybe 240px was for PCs, not TVs?)
(or maybe Amiga may use a higher spacing between scanlines than PCs monitors?)

The fact is that everybody at the time knows that Amiga NTSC was 200px height + borders (400px if interlaced).
See examples here: https://amiga.lychesis.net/articles/ScreenModes.html

My request was to add Amiga NTSC resolutions to that list:
Pal resolutions are listed.
Thanks
