Tinkering for fun with 3D draw distance

On some 3D driving games for MAME (Crusin USA for example) the emulation on PC seems to outperform the original hardware.
How easy would it be to increase the draw distance to eliminate polygon popping for games like this?
Just for sh*ts and giggles of course!

To be clear, that would require modifying the actual code of the game. It's not something we can force on it from MAME. Secondly, the draw distance is usually baked pretty deeply into the engine on polygonal racers and isn't a trivial adjustment. Among other things, you then have to run collision detection further out so the required CPU time increases at a pretty rapid clip.
I'm not saying it's impossible, but it's nowhere near easy either. Plus, Crusin' runs on a pretty unusual processor so not many people could even do it.

Well that is just a bummer!  Thank you for the clarification!
