Changes

An '''emulation box''' is an unofficial term for a device built with the specific purpose of running emulators. They generally consist of overpriced and locked-down ARM microcomputers and some are more so just "collector's items". They should be avoided as your computer will generally provide better performance overall.

*[[Retron5]] ($159.99) - Emulates NES/GBC/GBA/Genesis/SNES and includes cart readers for those systems. Uses [[RetroArch]], [[Snes9x]], and [[Genesis Plus GX]] for its emulation.

*Sega Genesis Flashback (AtGames) - Produced under license from Sega. Emulates the Master System and the Sega Genesis. Very disappointing and the ensuing outcry has led Sega to drop their planned further partnership with AtGames for their actual Sega Genesis Mini.

===Controversies===

Some of those products have attracted the ire of parts of the emulator community over issues not necessarily related to the product's quality, but ones related to open source emulators. In some cases, it's because negotiations with open source emulator and/or frontend developers fell through and the company used a "lesser" option as a replacement. In others, an arrangement was reached, contracts and money were exchanged only for the project maintainers to turn out not to have gathered the complete consent of all contributors, some parts are licensed as a strictly non-commercial license, and similar issues. Sometimes, it might have to do with an incomplete source code release from companies that have to abide by GPLv3 obligations. And of course, the company might be acting malicious towards emulator developers.
