Video
Use the decompilation port for unstretched scaling and support aspect-ratios other than 5:3.
- Glitches appear in aspect-ratios wider than 5:3 (1.66:1) with the Steam scripts. Use the mobile scripts to alleviate the glitches with wider aspect-ratios.[citation needed]
- The game's graphics in this re-release appear rather blurry, regardless of resolution selected and the in-game Nostalgia video filter does not provide a clear nearest-neighbor image. Use the decompilation port for native Nearest-neighbor/pixel-perfect support, or follow this guide by TheA_Gamer554 for a workaround to make the vanilla game run in a pixel-perfect scaled image; pre-made 4:3 and 15:9
