The Guide to Aspect Ratio’s & Resolutions on Retro Handhelds
Aspect ratios and system resolutions are one issue we've encountered while utilizing vintage handhelds. Which ratios were the original ones? How much does it cost to upgrade to 1080p? How about 4K? The software doesn't explain what 8x resolution is. What is that resolution?
Here, we'll address all of that and more.
The upscale required in the emulator to pass those resolutions is shown by the values below 720p, 1080p, 1440p, and 2160p. To prevent partial upscales, all figures are rounded to the closest whole number.
