Description
On a 4K display using integer scaling and Aspect Ratio: Core provided, games which mix 240p and 480i/480p modes scale those modes to different final resolutions, (Core provided)x2160 for 240 (9x integer scale), and (Core provided)x1920 for 480 (4x integer scale), resulting in an inconsistent presentation.
If we could define a maximum allowed final integer scaled resolution on a per-axis basis, this could be avoided, without losing the benefits of Aspect Ratio: Core provided or Fullscreen.
Example: if we could set Maximum Integer Scale Resolution (Y) to "1920", both 240p and 480i/480p would scale to a consistent (Core provided)x1920.

Research direction
Start by tracing RetroArch's integer scaling and Aspect Ratio: Core provided display configuration, focusing on how 240p and 480i/480p modes calculate final resolutions. The feature is done when per-axis maximum integer-scaled resolutions can be configured and both modes consistently use the configured Y limit, including with Core provided or Fullscreen aspect settings.
