in order from left to right: original resolution, 4x upscaled, 4x with softrasterizer turned off

yeah, that's some *crag*ing HD mario kart DS right there nigga

how to:

1. download newest build from here (windows only)

2. acquire roms

3. do this

4. and this

it's gonna run slow at 4x, but 3x and 2x are faster, turning off softrasterizer seems to tune up to both the graphics and performance, but I don't know if it does this with all games
