Fonts not readable on small screens

[migtorr]

Hi, on the retroflag gpi the game looks ugly and the fonts are unreadable, I think is due to the low resolution of the screen. Is there any way to change the game resolution?

Wow, really nice seeing the game on a retroflag :) Yes, the game has a fixed internal resolution, which is then scaled depending on the screen or windows size. Scaling down unfortunately makes thin lines like text and ghost borders ugly. As a workaround, on small screens ghost pieces could be filled, but for fixing the text probably a secondary font rendering would be needed, using some low-resolution font.
