The Sega CD was '''[[wikipedia:Nintendo 3DS|Nintendo 3DS]]''' is an eighth-generation handheld game console by Nintendo, released on October 15March 27, 1992 and retailed 2011 for {{Inflationinflation|USD|299.99249|19922011}} . The original model and the 2DS had a Motorola 68000 CPU dual-core ARM11 MPCore at 12.5 268 MHz and 64 kbit a single-core ARM9, 128MB of RAMand 6MB of VRAM, and a DMP PICA200 GPU. The Sega 32X was released on November 21New 3DS and New 2DS XL models upgrade this to an 804 MHz quad-core ARM11 and 256MB of RAM, 1994 for {{Inflation|USD|159.99|1994}}. It had 2 SH-2 RISC CPUs at 23 MHz along with 256KB an extra pair of RAM shoulder buttons and 256KB of VRAMa right analogue stick.

Genesis emulation The most notable feature of this console is very good, with a high degree the use of game compatibility (many of them claiming nearly 100% compatibility with commercial games, including Virtua Racing)[https://en. They are available on many platformswikipedia. Many Genesis emulators also feature compatibility with the [[Master System emulators|Sega Master System]org/wiki/Autostereoscopy autostereoscopic] (SMSglasses-free)3D, which can be configured using a slider. This was omitted on the cost-reduced 2DS and New 2DS XL models, which was released due to eye health concerns with children whom Nintendo advised not to use the [[Master System emulators|Game Gear]] 3DS's stereoscopic mode (GGthough it is speculated that said advisories were more for liability reasons in case of a health-related lawsuit) as well as earlier Sega consoles. Genesis-based arcade boards and the [[Sega Pico]] are still sketchy, however. __TOC__

==Lock-On Emulationissues==Lock-On Technology is a unique feature found on Sonic & Knuckles cartridges for Citra currently can't emulate any of the Sega Mega Drive/Genesis that allowed a player to 3DS's online features aside from LAN multiplayer. It can't connect an older game to the cartridgeNintendo's pass-servers but users can create rooms and play through port for extended or altered gameplaythe internet.

* With Sonic 3: Unlocks an alternate version of Sonic 3 with more levels.* With Sonic 2: Unlocks an alternate version of Sonic 2 with playable Knuckles.* With Sonic 1: Unlocks the Blue Sphere minigame with a level select to all possible levelsCorgi3ds currently can't run any game without heavy stuttering.

The Sonic & Knuckles cartridge Citra emulates the home menu although you can lock 't launch anything on to other cartridges:it.

* Smaller than 2MB==Game images=====3DS vs. CIA===<!--this section is pretty inaccurate-->There are two big types of 3DS game images currently: Will play a single random level from the Blue Sphere minigame generated from ;NCSD-type: Includes '''.CCI''' (CTR Cart Image), aka '''.3DS''' - data in on physical carts, can be executed right off the headerbat, not used much since no one bothered to develop a CFW solution to load them yet (besides converting them to CIA) and only overpriced flashcarts (Gateway/Sky3DS) can load them.* Bigger than 2MB;NCCH-type: Will boot Includes '''.CIA''' (CTR Importable Archive) and '''.CXI''' - installers that unpack game data to Sonic & Knucklesthe SD card or the 3DS NAND memory.* Has Battery Pack: All save data will be wiped outSome homebrew apps (FBI, DevMenu) can install CIA files on 3DS systems with CFW installed. Digital games are often distributed as CIAs.

Most emulators don't support Lock-On save *Note that CTR (Citrus) is the internal code names for Genesis Plus GX, but there are pre-combined ROMs for the Sonic trilogy available online that can be played as a regular Megadrive ROM on any emulator and still work. The Sonic 3 Complete romhack also achieves the same purpose3DS.

Genesis Plus GX's [[RetroArch]] core includes true Lock-On emulation. From the Core Options menu, you can enable the Lock-On feature for either Sonic & Knuckles, Game Genie, or Due to one format being so far restricted to overpriced flashcarts and the Action Replay very slow Citra development (Pro) -- meaning playing on a real 3DS is still the latter two using a different technology but with similar effects. Setting this option preferred way to anything other than "Off" will enable Lock-on to the cartridge you're currently playing as. After resettinggo), the game will boot CIA format is preferred in Lock-On modemany sharing websites, downloader tools and even tools to dump your own games.

The following files need However, converting a CIA image to be under the directory for BIOS files 3DS format (usually "system"):* sk.bin (Sonic & Knuckles (2 MiB) ROM)* sk2chip.bin (Sonic & Knuckles UPMEM (256 KiB) ROMand vice-versa): If you can't find it online, extract it is still possible with a hex editor from a pre-combined Sonic 2 & Knuckles ROM from offset 00300000 to the end no loss of content. Read the ROMEncryption section below for a guide.

For GG/AR, the files needed are areplaySome outdated dumping utilities intended for use with Citra (like braindump) produce damaged decrypted 3DS images that can't be easily converted back.bin and ggenie.bin, but most emulators support cheat codes from these nativelyNo known solution exists so far to fix those dumps.

==Mega Drive Plus / Genesis Plus=Encryption===Most dumps online are also encrypted. This encryption poses no problem for playing game images on a real 3DS since it can deal with that encryption with internal keys included in the bootrom, but becomes a problem when trying to emulate them on PC. '''Citra requires additional encryption keys to play encrypted games.''' If you want to play encrypted games on Citra without these keys, you'll have to convert your game images to the decrypted format.

The Mega Drive Plus / Genesis Plus Formerly, decrypting those ROMs used to require real 3DS hardware (sometimes abbreviated as MD+bafflingly enough, Citra devs still ask users to do this even nowadays) is . It required files generated by a special mode for certain Genesis games real 3DS called '''xorpads''' unique to that use enhanced CDDA tracks with a Sega CD. This was not used in any official games, howevergame version, using the mode itself was first used in encryption engine within the first batch of Pier Solar releases3DS. This feature was been [https://downloads.terraonion.com/public/MegaSD_DEV_Manual.pdf documented] to After this part, these xorpads (which are big) can be used on Terraonion's Mega SD flash cartridgewith PC tools (or other 3DS-based homebrew) to produce the decrypted game image. After that, some 3DS homebrew (Decrypt9, GodMode9) included tools to directly convert encrypted images to give similar effects for Genesis games in decrypted images with a way how MSU-1 does in patched SNES gamessingle button press, but those still require a real 3DS.

CurrentlyThe game changer was the sighax exploit, no Genesis + Sega CD emulators feature this function, although there is allowing to dump the 3DS bootrom which includes these encryption keys. This file can be downloaded from the [[Emulator Files#Nintendo 3DS|Emulator Files]] page. You can then use a program like '''[https://githubgbatemp.comnet/ekeekethreads/Genesistutorial-Plusextract-GXdecrypt-games-nand-backups-and-sd-contents-with-fuse-3ds.499994/issues/297 plans fuse-3ds]''' to decrypt games using this file. Simply place boot9.bin in the same folder, run the program, mount the encrypted .cia or .3ds, and find the '''decrypted.cxi''' file inside (usually in the first folder). Citra should be added] in Genesis Plus GXable to load this file without issues.
