I was curious to see if the PC version of PBA Tour (called PBA Tour Bowling 2001) could connect online with the Dreamcast version that we all know and love. The answer is that it almost works. After setting my PC's DNS to 46.101.91.123 and setting up an account the same way I would on the DC version, I was able to enter the ShuMania lobby.
(sorry for the messed up image formatting, you can click them to view them properly)
My Dreamcast was unable to find games created by the PC version, but the PC version could see and join games created by the DC version.
Going to start the game caused an error on the PC version however.
I don't really plan on messing with this further as my Dreamcast can't even play this game with other Dreamcast players, but it was neat to try it out since it doesn't seem like anyone has.
You can download the PC version here
