    Remix OS

    Remix OS

    Remix OS for PC is a productivity focused, desktop version of Android.

    Given its lightweight size and system requirements, Remix OS for PC is well suited to be installed on a USB drive (8GB+) and used as a portable workspace securely containing the user’s documents and apps. This particular use case has significant advantages for users within emerging markets where shared PCs are more common. A key feature of Remix OS for PC is multiple window support, and this has been vastly improved in the migration to Marshmallow. Significant examples include: ● New button has been implemented that resizes a window to fit specifically to the app’s content - ensuring optimal layout is maintained ● Video-based apps now open up in full-screen when you maximize the video rather than staying in a small framed window ● Resizing windows manually can now be initiated anywhere along the edge of the window (other than the top edge), rather than just on the bottom right corner

    Remix OS

    Remix OS

    Android OS for Windows PC systems

    Remix OS is a free Android version made by Jide, the company behind this operating system. This OS comes with certain basic Android features adding some missing functions that are present for Mac and Windows users. You install it on a USB and boot directly from that. It’s compatible with Intel and AMD processors, so it runs on almost any machine, and unlike other solutions, it has a dedicated desktop user interface just like the operating system you’re already used to. That means that when you open an app, it doesn’t take up the whole screen like it would on an Android tablet; it opens in its own window like any other desktop program. This allows you to use Chrome alongside Word, or Google Maps, or YouTube, or just about any other Android app. Remix OS is totally free to download and use. This is an alternative to running an Android Emulator for Windows.

    zBoy

    zBoy

    a multiplatform, full-featured GameBoy classic emulator

    zBoy is a multiplatform GameBoy emulator that provides a load/save feature, can perform PCX screenshots either manually or automatically (every few seconds) and emulates an internal battery for ROMs that were designed to use one (this allows to use the internal save option provided by such games, remember highest scores, etc). zBoy supports some additionnal features, too, like intelligent saving of hi-scores for some games that aren't able to save their hi-scores table by themselves because of the lack of a battery-backed RAM on the cartridge, and improving screen's resolution output using graphic algorithms like Scale2x, Scale3x, eagle... Here you can see a comparison between graphic algorithms supported by zBoy. This is also one of the very few GameBoy emulators that provides a 2-gameboys link emulation, which makes it possible to play some games in 2-players mode on a LAN. The emulator is available for Linux, DOS and Windows (but should compile for other systems, too).
