To play PSP games on computer, at present there are only three PlayStation Portable console emulators available: the currently best PSP emulator - PPSSPP, the earliest PSP emulator developed based on Java - JPCSP, and PCSP - a discontinued but very good PSP emulator developed by partial members from the development team of PCSX2.

For files without an extension name, or some proprietary format of files that any common software cannot read/write, if you're sure it's a media file, then you can try using MediaInfo to detect its file metadata first. Alternatively, you can also direct use FileAnalysis to analyze its file type, thus determine that what software generated, encapsulated or encrypted this file.

Often someone complains that the traditional Windows logon authentication way using password is not convenient enough (especially for those PCs set up with a very complex login password), and its security is not high enough. This case, you can try Rohos Logon Key this useful tool from Moldova. It is capable of using a USB flash drive for system logon authentication. That's to say, you don't have to login Windows when it boos by inputting your password, instead, that just needs you to insert the specified USB drive.

Whether on your own computer or a public one, we always have some important or privacy-related files and data that do not want others to see or get. In this case, what we can do is to use some software to protect them in primarily five ways: monitoring (passive), hiding (junior), locking (can be easily hacked by advanced computer users), password protecting (ditto), encrypting (the safest, but not convenient).

Snipaste (formerly called: PicNotes) is a compact, simple but overwhelmingly powerful and efficient screenshots making tool from China. Its independent developer spent 3 years to create this very special screen capture application, which combines screenshot + annotation + mapping these 3 major functions in one place. It is currently the only real edge tool for making screenshots on Windows, Mac and Linux! In contrast, you will immediately realize that - the working efficiency of using the traditional screen capture software is too low, and your screenshots operation and using habit must change dramatically in the future.
