ACE3DS is a R4 compatible emulator for the Nintendo DS & 3DS system line, and can emulate primarily the DS along with various 8-32 bit consoles. Similarly to PocketNES the software was originally developed and sold for hobbyists to store their ROM collections and Homebrew software on rewritable flash cartridges, but was soon used pirates to sell multicarts loaded with usually 200-500 preloaded DS games of mixed quality.
ACE3DS boasts a lot of features including cheats, online firmware updates, DS Download Play support, a vast collection of emulatable consoles ranging anywhere from the Famicom to NeoGeo, and a large ROM capacity. Over the years many accessories and upgrades where released adding many more features to the already present features of the standard cartridge.
Usage in Pirate Multicarts Edit
ACE3DS is the most commonly used emulator in DS multicarts by pirates. These multicarts usually contain around 200 to 500 games with the first couple being games made by major publishers (Nintendo, SEGA, GAME FREAK, Activision, etc.) however as the higher number games mostly consist of a mix of shovelware and more games by the aforementioned developers. Some title are featured twice on carts as pirates tend to use a mesh of European and American ROMS of games, sometimes even featuring homebrew titles. Along with this, pirate versions tend to crash and corrupt game save more often while also contain the infamous R4 bomb which is common in unlicensed flash carts making the cartridge unusable after activating on it's set date, however it can be bypassed by setting the console's internal date backwards. These cartridges are mostly sold on websites such as ebay for usually around $18-30 depending on the game count, they are paired alongside a plastic case featuring random art from various games featured on them with the cartridge's title and a false E for Everyone rating despite some carts featuring E10+, T. and M rated games. The cartridge itself is a standard R4 except for having a new sticker usually containing the same art as on the case with the cartridge's name.
