Dgvoodoo has a brightness and color slider and it has anti-aliasing.
I added a screenshot with both effects subtly applied.
EDIT: I found a better alternative called DxWnd here: http://sourceforge.net/p/dxwnd/home/Home/
This program was created to be used as a compatibility layer for old games.
The interesting option are:
1) the FPS limiter under the timing tab
2) 'Windows 95' under compat. tab
3) 'DirectX hook version' to '1~6' under the Directx tab.
4) 'Optimize CPU' on the main tab
I found 2) and 3) to prevent random game crashes, but 'Run in window' on the main tab must be turned OFF otherwise the game will just insta-crash or lag.
The strange thing is how the fps number works, as it sets a delay before the limiter will kick in. I found 33 msec to make the game run at its intended 30 fps, but maybe another number is necessary on PC's with a higher/lower spec. Can someone verify this?
One problem: (dgvoodoo has it as well)
Setting bilinear/trilinear filtering results in extreme lag (at least, on my Pc). Only anti-aliasing can be used, but DxWnd doesn't have this option. My solution is to use both programs simultaneously. This suprisingly didn't gave me any side effects.
Yeah, just look at the game's readme. It got released with quite serious know issues. But worse of all is the lack of FPS limiter. Just WHY? My first PC was a Pentium III and it ran the game about twice as fast, making it unbeatable.
EDIT:
1) DxWnd doesn't work on windows 10
