I'm curious;
How do you create new Voodoo 5 drivers?
What software do you need?
Wanna give driver creation a try myself but I have no idea where to begin.
Learn how to code.
You need to have a driver sources to compile you own driver. You may ask Amigamerlin or SSFT and I think that you must be skilled developer if you have chosen this hard task.
I hope that you will success.
