Emulator commands

All emulator commands are done through menu bar at the top of the program main window.

• About DCTO9P
  Click [?] button on the right of the menu bar.
  
  


• Settings
  Click [Options] button on the right of the menu bar, and select Settings...
  The buttons on the right of each parameter can be used to change the value.
  [Restore default values] button initializes all the values.
  Increasing display speed and processor speed dramatically increases resource usage. With a slow computer, when audio output is poor, you need to decrease display speed until you get good sound.
  
  


• Keyboard layout
  Click [Options] button on the right of the menu bar, and select Keyboard...
  Key codes depend on operating system and keyboard type. It is not possible recognize every configuration. Default in dcto9p is a standard French keyboard with Windows XP or Linux. For other configurations the keyboard layout must be redefined. It is a straightforward process : each TO9+ key is emulated with one key of the actual keyboard. Type a key on the keyboard. Matching TO9+ key is shown. If not correct, click the corresponding TO9+ key picture. Repeat this process for each of the 84 TO9+ keys. Then you should save the customized keyboard layout, and it will be used each time you will run DCTO9P.
  
  


• Joystick emulation
  Click [Options] button on the right of the menu bar, and select Joysticks...
  Joysticks are emulated with the keyboard (use preferably the numeric keypad). For each joystick, four keys have to be choosen for directions and one for fire. Process is exactly the same as for keyboard layout. Please note that the same key can be used for both TO9+ keyboard and TO9+ joystick emulation. Make your choice to avoid mix-up when running a program testing both keyboard and joysticks.
  
  


• Load tape, disk or MEMO7 cartridge
  Click [k7], or [fd], or [memo] button of the menu bar...
  Using [k7] button, tape images (.k7 files in software subfolder) are listed in a clickable menu. Click the file name to load the tape. You can also click [unload] to unload the tape, and [next...] or [back to the beginning] if these lines are displayed. Same usage for [fd] buton with disk images (.fd files in software subfolder), and for [memo] button with MEMO7 images (.rom files in software subfolder). Don't forget to check settings for tape and disk write protection. To make an empty tape or disk, create an empty file in software subfolder, and name it with .k7 or .fd extension. Please not that you cannot use a new disk before formating it with Basic 512 DSKINI command.
