Apparently, the better buttons for shmups are the Seimitsu buttons correct? I see they have them here:

To use the HRAP on Genesis and Saturn I could buy Tototek adapters:

And for Dreamcast, I could get the Total Control Plus:

I don't know...maybe I'll keep the X-arcade stick to play 2 player fighters w/friends and get the HRAP for shmups. I'm not sure if I can even afford this right now.

Anyway, does this sound somewhat sane? Thanks for your help!
