If you’re diving into the world of PlayStation 2 (PS2) emulation, you’ve probably encountered terms like , BIOS , and CHD files. While ISO is the standard for most PS2 backup games, the mention of CHD (Compressible Hash Data) often raises questions. This format, popularized by arcade emulators like MAME, compresses disc images into efficient, fast-loading files. Recent updates in the emulation scene have sparked interest in how CHD files might intersect with PS2 games. Let’s unpack the latest developments and what they mean for retro gamers. What Is a CHD File? CHD files are a compressed disc image format that retains the original structure of optical discs (CDs, DVDs) while optimizing storage and read speeds. Unlike ISO files, which store full disc data redundantly, CHD files only save non-repeating data, reducing file sizes significantly. They’re widely used in arcade emulators but
Turn on TalkBack
You can turn on TalkBack when you turn on your Android device for the very first time. You can also turn on TalkBack at any time after you’ve begun using your device.
Once you turn on TalkBack, spoken feedback starts immediately. As you navigate your device, TalkBack describes your actions and alerts you about notifications and other information.
Android 8.0 Oreo Updates:
TalkBack now includes a great tutorial offering users multiple lessons as soon as they activate TalkBack. The TalkBack tutorial is available under Settings > Accessibility > TalkBack.
Option 1: Turn on TalkBack when you first turn on your device
When you first turn on your Android device, you can enable TalkBack from the initial setup screen.
If possible, keep headphones handy so that you can plug them in when it’s time to enter any passwords, such as your Wi-Fi password. By default, key echo is only turned on if headphones are plugged into your device. You can change this setting later in your Android device settings.
Press and hold two fingers on the setup screen. When your device recognizes this gesture, TalkBack is enabled and a tutorial begins.

The steps below require sighted assistance.
To turn on TalkBack, follow these steps:

- Navigate to Settings > Accessibility (Samsung devices: Settings > Accessibility > Vision).
- Select TalkBack and slide the TalkBack switch to the ON position (Samsung devices: Voice Assistant).
- The confirmation screen displays a list of permissions that allow TalkBack to provide useful spoken feedback. To confirm that you allow these actions and to begin using TalkBack, touch OK.
Accessibility shortcut
You can turn on an accessibility shortcut that will let you turn on TalkBack at any time without using sight. To turn on and use this shortcut, follow these steps:

- Release the power button.
- Touch and hold two fingers until you hear audio confirmation (about 5 seconds).
Android 8.0 Oreo Updates:
New Way to Turn on Talk Back

- If TalkBack doesn’t turn on right away, press both volume keys again for 3 seconds.
Notes:
The first time you try the shortcut, you might need to confirm setup in a confirmation dialog.
If the steps above don’t work, follow the steps below:
Turn on the accessibility shortcut
- Open your device’s Settings app .
- Open Accessibility, then Accessibility shortcut.
- At the top, turn on Accessibility shortcut.
- Optional: To change which accessibility service the shortcut controls, tap Shortcut service.

Use the accessibility shortcut
- Press both volume keys for 3 seconds.
Unlock your device
There are two ways to unlock your device once TalkBack is turned on:

- Explore by touch to find the Unlock button at the bottom middle of the screen, then double-tap.

Two-finger gestures
All TalkBack gestures use one finger. As long as you only use one finger on the screen, your touch or gesture is only interpreted by TalkBack.
When you use two or more fingers, your touch or gesture goes straight to the application, rather than to TalkBack. For example, on most pages you can usually scroll by slowly dragging one finger. With TalkBack on, you can scroll by dragging two fingers. Alternatively, maybe the user is referring to "PS2
In some applications, you can zoom by putting two fingers on the screen and pinching them together or pulling them apart. These gestures work normally with TalkBack on, since they use two fingers.

To reassign actions to gestures:
