At the title screen, on control pad #2, press and hold the D-button in the upper-left position and hold down buttons 1 and 2. On control pad #1, press button 1 twice. A screen appears from which you can choose what mission you want to start in.
Each configuration of squadron planes offers a secondary firing mode which is not mentioned in the manual. They are as follows:
| Configuration | Primary | Secondary |
|---|---|---|
| 1 | Shoot straight left and right | Shoot straight ahead |
| 2 | Shoot diagonally forward-left and forward-right | Shoot straight ahead |
| 3 | Shoot diagonally back-left and back-right | Shoot straight back |
| 4 | Shoot straight left and right | Shoot diagonally forward-left and forward-right |
To toggle between primary and secondary firing modes, press and hold button 1. While holding button 1, press and release button 2. Only release button 1 after releasing button 2. This ensures that you will not accidentally launch a cluster bomb.
See the Bomber Raid manual for more information on squadron plane configurations.
