Seriously? Within this year? Are you telling us that we cannot use a product for a whole year? Why do you need so time to fix one driver? If you cannot do it, release the source code and someone else would.
I hacked together a driver a while back for Vista64, trouble is it wasn't stable at all - that was me with very limited skills hacking the XP64 drivers. With source release it'd take less than an hour I'm certain.
Like I posted earlier, they will be losing out on a lot of orders due to this.
I tried before and failed. One interesting point, if you get the Direct X SDK and try the DXInput test then the joypad buttons are all recognised - force install of WinXP64 drivers. There is nothing fundamentally wrong, just needs an application profile of some sort.
Older versions of windows allowed you to use pretty much anything as a generic profile (8 button controller, 2 axis etc). From Vista up this seems to have disappeared.
Someone with a bit more skill than me might be able to suss something out. I feel a bit sorry for the Admin on this board, it isn't them setting the policy.
