I installed the patch and it worked fine.
It's a nice little project, but I'm still really at a loss as to the purpose - I never had a problem with 640x480 3D res, my main issue was with the 320x240 resolution of the backgrounds. From reading other posts in the forum, I understand that it is no easy task to implement high-res / interpolated backgrounds, which is a shame, because that's what I really hoped this patch was for.
as it stands, the actual effect of the increased resolution is minimal, but still, nice work, it's good to see the fans at home keeping old games alive and even improving them.
