Please do.
After tons of time, monies, and frustrations you'll end up with a virtual pinball machine; seems more like a punishment than a reward honestly.
EDIT: It's actually more "fun" to play on something small like PSP than a big rig anyway

I'd love to help you get started but the questions you are asking aren't really a quick answer type of thing.

Two things:
- Sounds like you are talking about building your own table in virtual pinball (not build a cabinet). Two very different "Help me build" conversations.
- You must get VP or Future pinball running tables BEFORE you try to build your own game. Trying to build a table with a load that is buggy will make your life a million times harder as you wont know if it was your code that bugged things out or just the foundation.

Are you looking to build a custom table or recreate an existing game? VP plays much better than Future Pinball IMHO but Future Pinball is much easier to design and script a game. VP has gotten better with some of it's build in modeling though but VP is more about recreations and utilizing the scripts in ROM and you just mapping switches, coils and lights to those inputs in the script. If you can't write your own code and I mean write it really good, stick to recreations first to learn the basics. Scripting a game from scratch is a MASSIVE learning curve.

My last suggestion. Don't come to Pinside for these questions. Pinside is a great resource for real games but not all that great for VP conversations. There are a couple VP guys/gals around here but few and far between. Go to a place like VPforums.org as that is where most of the builders and coders hang out. There are also resource videos to help with the basics of learning to build a game.
