As in the Nintendo DS game console, some programs are configured to be used by left-handers or using the machine in an upright position instead of landscape. Varying the designation from left-right and up-down etc. The configuration of some keys is reversed in some commercial regions; Thus, in the European PSPs, the X key produces the function of the Circle key of the US and Japanese PSPs.
The console comes with 17 buttons, some less on the new models, many of which are multifunctional or bring several positions, such as on-off-lock. Some are common to most third-party consoles.
These include at one end a crosshead or digital pad, with four directions, as in Nintendo, which allows scrolling through the menus and control of some games. At first glance they look like four keys but when dismantling the case, you can see that it is a single crosshead.
On the opposite side there are four buttons that correspond to the standard marked by the PlayStation desktop models, that is, triangle, square, X and circle (Triangle Square X Circle)
- The X key selects the highlighted option in the menu and generally selects the action.
- The Circle key generally cancels or aborts the action. In the menu we move back to the previous “folder”. This key and the previous X can have their function reversed, depending on the application, the source language of the games or the homebrew software that we have as an operating system.
- The Triangle key when playing content shows us the “control panel” with all the choices.
- The Square key is a wildcard, auxiliary or subfolder key, whose function may be non-existent or usually change as selected earlier to a higher degree in the previous three, or combined with the crosshead.
- Two large rectangular plastic buttons, called L and R triggers, are also analogous to the left and right Nintendo DS triggers.
- It also presents the SELECT and START buttons.
Among the exclusive buttons of the PSP are:
- Next to the crosshead is the mushroom button or analog stick that has the same function as the crosshead and also controls the cursor in some applications.
- The HOME button called PS by PlayStation in the new models, shows the “main menu” or cross media bar in English (XMB). It matches the “desktop screen” of a pc, showing us the “shortcut”. On consoles with custom firmware, you can exit the program that is running. Two volume controls – and +, one key to choose the intensity of the screen brightness.
- The “sound” button labeled with the Music-eighthnote.png symbol connects-disconnects the sound and with the headphones plugged into the headphone output, allows you to change the sound tone between 6 available: jazz, pop, rock, heavy, unique and off. Once turned off, the sound is reconnected by pressing the Music-eighthnote.png key again or the – and + keys.
- The “screen” button changes the intensity of the backlight and if it is held down it turns off the screen to save energy by continuing to play the sound.
On the sides of the console there is the key of choice between Memory stick or communications port, which blocks access to the Wi-Fi connection, is signaled by two LEDs, one for each function. On the opposite side the mentioned on-off-lock key that among other functions such as pause, or standby mode in energy saving, locks the console keys in one of the positions. It is signaled when the HOLD LED is illuminated in orange light. To remove the battery or insert or remove a UMD optical disc. You must also press the PUSH and OPEN keys respectively on a fat (psp 1000) and for the slim (psp 2000 and 3000) only the lid. It also has a cover with the MagicGate inscription that hides the Memory Stick Duo slot. However, the use of the name “MagicGate” whose literal translation is “magic entry” is purely coincidental. “MagicGate” is the term that gives name to the “copyright protection technology” developed by Sony Corporation. In this context it indicates that the Memory Stick Duo are compatible with the format.
