The '''[[Wikipedia:Xbox One|Xbox One]]Project Nested''' is an eighthopen-generation home video game console produced by Microsoft on November 22, 2013 and was retailed for {{inflation|USD|499|2013}}. It had an AMD 8-core APU at 1.75 GHz and 8GB of RAM. It has an AMD GPU on the AMD Radeon GCN architecture. Early in its life, it was heavily criticized for intrusive source [[wikipedia:Digital rights managementNintendo Entertainment System emulators|DRMFamicom (NES)]], such as always-online and lack of used game sharing. These have since been removed. Notably, this console runs on emulator for the [[wikipedia:x86Super Nintendo emulators|x86Super Famicom (SNES)]] architecture with a modified Windows OS, so it is essentially a watered-down PCwritten 3/4 in 65C816 assembly and 1/4 C#.

===Emulation issues=History==Despite this console using the same architecture The project began in 2015 as PCsa NES emulator on PC. The emulator was running at full speed, and development was going "pretty well", but was not considered challenging, so it is was decided to move it to the SNES. After three years of casual development and thinking about how to achieve 100% performance (otherwise it would have been considered pointless) until summer 2018, the emulator began official development. As of v1.3, the model has been improved since, but not any easier by much. The speed was calculated by multiplying the average amount of times each instruction executed each frame and the overhead. However, the maths were 5 percent off on first implementation. Most implementations were made after approximately one month. ==Overview==The emulator was inspired by the SNES originally being designed to emulate than other consoles as be backwards-compatible with the architecture used is complex NES and Myself086 wanting to code a JIT (Just-In-Time) compiler. Emulation works by converting NES ROMs into SNES ROMs using a JIT (Just-In-Time) and uses undocumented AOT (Ahead-of-Time) compiler (with various options) for Windows, allowing them to run on SNES hardware. We have no way  Save files are created after the software title runs for a while. These can then be added to the ROM, often improving performance, vastly with some titles, and not much with others. The following are required:* Up to 8MB of fast HiROM (slow HiROM support planned)* 8KB to 256KB of SRAM (at least 16KB is required to know create feedback for sure because the console is not even hacked yet exe)* A battery if required by the software title ===Compatibility===* [https://docs.google.com/spreadsheets/d/1xKZIyNz1DSI3ZBdMfaTEaa_9b6IEABx-ZPwOb6XqcLQ/edit?usp=sharing Compatibility List] Emulation occurs at up to a degree 60FPS (frames per second) with audio support, but occasional minor slowdown may occur. Software titles that use mappers 0-4 and 7 are playable, with mappers 1 and 4 having minor glitches, which may reduce compatibility levels with titles that people can look use them, mappers 5, 6, 8, 11, 12, 16, 18, 21-26, 32-34, 36-38, 40, 42 and 66 unplayable, mappers 9 and 10 unlikely to be supported due to it being declared impossible to accurately emulate CHR bank switching, and 14 and test stuff 17 due to being "copier mappers", and tell for surethe rest, up to 255, being unknown. Additionally, iNES 2.0 is not supported. Out of the 456 tested titles, 37 (7.96%) are fully playable, let alone for 92 (19.78%) are playable but need a full emulator playthrough to test, 47 (10.11%) are mostly playable, 161 (34.62%) crash in the intro or early in-game, 127 (27.31%) are unplayable and 1 (0.22%) is unlikely to be writtensupported. It should For example:* Punch-Out!!! is unlikely to be supported due to using mapper 9/MMC2, due to difficulties in implementing mid-scanline memory bank changes when drawing characters FE or FD, or sprites, the hardest to implement. This is not as problematic with the background, as the window can be noted used to draw and switch the characters.* The graphics in Super Mario Bros. 2 displayed incorrectly and the American version reset after hitting a Shy Guy until v1.4. Some time before the [https://www.youtube.com/watch?v=TthFh27Mx5k Sharopolis interview] on July 10, 2021, the latter issue was reverse engineered and figured out, also fixing many other games that mistakenly reset.* Elite is being used as a model to "aggressively" optimize the vast majority EXE in AOT compilation, making emulation run at the same speed, or faster if possible. The game runs slowly with flicker and does not support shooting as of v1.3. Additionally, one fully playable title, Battle City, was mostly playable from v1.1 until v1.3, when it hung after the game over screen with visual glitches in [[Mesen]]. Others run with minor glitches or require certain options, such as NMI at vblank or stack native return, to be disabled. Overall, at least 50% of Xbox One games are expected to run in the future.
