The stick is analog, so depending on where the stick is pointed, the PC can decide what to do. If you have the stick in a diagonal position and the program is in 4-way mode, it won't send an input to MAME (or whatever emulator you happen to be running). It does not have a physical restrictor, so it won't feel like a 4-way, but it should act like one otherwise.
How much control over the program do you have? Could you program it that if there is a slight arc off center of the left/right up/down positions that it would still register? The reason being that if you don't have a physical restrictor the joystick will not automatically "guide" you to the correct up/down - left/right. I do play various games in the early 80's series (Pac-Man, Donkey Kong, Frogger, Dig Dug, etc). As far as I know with a standard 8-way used in a 4-way game, there will be problems if you hit a diagonal.
But my head did perk up when I started to read about the U-360 in which you can program it to NOT it two outputs on a diagonal, and avoid quite a few of the problems associated with using an 8 way joystick on a 4 way game.
Ultimarc's shipping is cheap and fast, so I wouldn't worry about that. I recently bought an AVGA from him, and I think it cost $11 to ship, and it arrived in Nevada from England in 2 days.Search for U-360 here, there is plenty to read on the subject. It seems to be a really popular item.
Oh! That is good news. I thought it would cost MUCH more to ship. Yes, I have been doing some reading on the U-360. I know it is expensive, but given my unique situation with a single player (or multi-player alternating) cabinet. It might come in handy in respect to allowing me to play a bunch of the 8 way games. Otherwise the choice would be either 8 way or 4 way games and get the appropriate stick. Of course that would limit the amount of games I could put on the machine.
The U-360 is an analog stick, so when it is programmed for 4-way, only the inputs in the 4 directions are used. It will work well as a 4-way, but since it is not physically restricted, it will not feel the same as a real 4-way stick.
That is about all I know about them as I haven't used one. If they were available when I built my panel, I may have used those, but I went with multiple controls since there really wasn't an easier option at the time.
I was thinking about going that route too when I had a larger cabinet in my possession, but I was forced to sell my house and now I am shoehorning myself into smaller quarters. So I have to scale down to something that could sit on a counter or mount into a wall. So large Frankenpanels and/or multi-player controls will be out this time.

Edit: I went straight to the horse's mouth and took a visit to the Ultimarc website.
Oh! The U-360 also has a built in 8 button interface as well? Hmmm, that DOES make the deal sweeter as I might not have to buy a separate keyboard controller interface.
NAWICE! You can also program diagonal games in too such as Q-Bert. Hmmm this IS becoming a sweet deal.
Ok, will do, thanx!
