As we know texture resolution in old games can be pretty low and bilinear filtering which is used universally can look pretty bad in this situation. High contrast pixels when stretched a lot form this 4-pointed star look - see the attached picture for an example.
So my wish is an ability to replace it with a better algorithm. See this comparison:
Beetle PSX emulator already does this, allowing to use jinc2 algorithm.
