Running 4DO for the first time
Loading the BIOS
The first time you run 4DO, there will be a message at the bottom of the window that says "No BIOS rom selected".
Click "Choose BIOS rom" and then select your bios rom file. It will be looking for a file with a .rom extension. Sometimes the 3do BIOS rom file you have will have a .bin extension. If this is the case, have the file dialog show all files. Then select your BIOS file.
It is up to you to find your own 3DO BIOS file or extract it from your own system. We will not help you with downloading BIOS files. Once you have the BIOS loaded, the BIOS screen should be running. It will be just like the 3do console was turned on with no disc in the drive.
Configuring the Controller
If you would like to use a joystick or gamepad with 4DO, connect it to your computer before starting 4DO. As long as your controller is connected and working before you run 4DO, it should be detected and will work in most cases. To configure the controls for the emulated 3DO gamepad, click "Options" from the top menu bar, then click "Configure Input Plugin". The controller configuration window will now be shown.
The configuration window allows for multiple configuration sets for each player (1-6). The easiest way to setup the controls is to click "Set All" on one of the sets then to hit a button or key for the current control. Which button on the emulated 3DO gamepad you are setting up is listed on the left side of the first set. If you need to change the control for one button, just click the control you want to change (click inside the set) and it will wait for you to press a button or key. When you are done, click the OK button at the bottom.
Playing a 3DO Game
There are two main ways of loading a 3DO game in 4DO. You can play games using a 3DO game CD, or you can load a CD Image file (*.iso).
Playing 3DO game CDs
To play a 3DO game CD, simply place the game disc in your cd drive of your computer. Then click "File" from the top menu bar, then click "Open Disc Drive" of the drive you put the game disc into. The game should begin loading.
Playing 3DO CD Image File
If you have a CD Image File of a 3DO game on your hard drive, you might be able to use it on 4DO. The image file has to be a .iso file. It also has to be a Mode 1 2048 bytes/sector image file. If it does not meet these requirements, you may be able to convert it or use a Virtual CD Drive. If it does meet the requirements, click "File" from the top menu. Then click "Open CD Image File" and select the .iso file on your hard drive. The game should begin to load. Games might also run a little better from .iso files too.
Playing in Full Screen
To play the game in full screen, you can use the shortcut F4 key. You can also click "Display" in the top menu and then click "Full Screen".
