There are a lot of options to configure the game to your liking, either about the playability or in the manner the game is shown to us. Some can be configured from the main menu and others can be modified by pressing certain keys.
ESC / SPACE / Start Button
Paws the game
CONTROL + M (at any time)
ACTION + JUMP + START (with game paused)
Exit the game and return to the main menu
F5 - reduce the window's resolution
F6 - increase the window's resolution
(Those changes will also alternate between 4:3 and 16:9 resolutions)
F7 - Alternate between 4:3 o 16:9 ratio
F8 - Enable or disable Aspect Ratio correction
F9 - Decrease the intensity of the scanlines
F10 - Increase the intensity of the scanlines
F11 - Change the color mode between:
Color - Black and White - Green - Orange
F12 - Change game version
CONTROL + F
ALT + ENTER
Switch between full screen and window mode
The game will try by default to use the same resolution of the window in full screen. If it's not possible, the resolution of your desktop will be used.
If you have an Arcade Machine at home, congratulations! Congratulations for the fact of having one, but also because this game incorporates an cabinet mode to be fully compatible with it.
To activate it, you must put a "1" in the arcade option on the config.cfg file and ¡voilá! The game will run in that mode. By default, these are the special keys that will become enabled:
F2 - Service Menu
F3 - Reset
5 - Coin 1
6 - Coin 2
ESC - Exit the game
If you are going to put the game on your machine, it is highly recommended that you go through the service menu and configure everything to your liking. By default, currency 1 is half credit and 2 is one whole, but you can configure it to be 2, 3, 4...
In this mode you have to insert coins to play, and the main menu ceases to exist giving way to a reduced one where players can choose their cats after inserting the corresponding credits. The first player can choose whether to play arcade mode in order to make the maximum score or versus mode to play against other cats, humans or machines.
The rest of difficulty settings, number of rounds, etc. will be configured by the arcade saloon owner (that is you!) in the service menu.
This space is reserved for things that I have forgotten to comment and that may be important. It's the good thing about the online user guides ... that they can be updated on the fly! :D
