Sorry I can't see the issue :/ I know nothing of baseball either.
Do you mean the sawtooth pattern on the white lines? If so, you can try reducing it by increasing the resolution, and enabling MSAA(in the configure hacks menu when using DX HW renderer) or FXAA(Shader configuration menu) anti-aliasing.
Yes you are right about the sawtooth pattern thats what i was trying to think of...but just couldnt thnk of if...
Yeah, do as FlatOut says, in GSDX, put the internal resolution up to native x2 or native x3, it will look a lot better
Okay what gs plugin do you recommend using for this game???
The only one that works properly, GSDX.
