Vita3k Work.bin File Info

On Windows, work.bin is a standard binary file. On Linux/macOS, it may appear without a file extension. You should never edit or delete this file manually while the emulator is running.

Developers and power users sometimes need to interact with work.bin directly. Here are legitimate scenarios.
