I've got two big issues setiing up the controls:
1 - I want to play 2 players games. I can assign keystrokes to buttons of the controller plugged in port 1, but not from a controller plugged in port 2. In port 1, both sticks, directional pad and all buttons are recognised, but none of those are recognised in port 2. I've only got 2 controllers plugged in, in ports 1 and 2, and both controllers are official Microsoft pads that work in all other games.
2 - After configuring controls during a game and returning back to the main menu, it asks you "Do you want to apply those as defaults for ALL games". No matter whether I choose Yes or No, whichever settings I have currently defined become the default for all games. This means that everytime I run a game in DosXbox, I have to reconfigure all my controls for this particular game again.
I could download the configuration from the website, but I wanted to try Micro Machines, which is not in the list, and I don't want to upload my config since I couldn't get input from the 2nd controller working.
