 ====== 3DO Interactive Multiplayer ======
-The 3DO Interactive Multiplayer is a fifth-generation home video game console released by the [[https://en.wikipedia.org/wiki/The_3DO_Company|3DO Company]] on October 4, 1993. It retailed for $699.99. It had a RISC CPU ARM60 at 12.5 MHz with 2MB of RAM and 1MB of VRAM.
+The 3DO Interactive Multiplayer is a fifth-generation home video game console released by the [[https://en.wikipedia.org/wiki/The_3DO_Company|3DO Company]] on October 4, 1993. It retailed for $699.99. It had a RISC CPU ARM60 at 12.5 MHz with 2MB of RAM and 1MB of VRAM. Its hardware was extremely sophisticated for its time, warranting its high price, but this would be a part of the reason for its market failure.
-^ shortname | ''3do'' |
+The 3DO company was conceived by Trip Hawkins, Electronic Arts founder. The console itself was not manufactured by the 3DO company itself, but the company created a set of specifications to be followed by other manufacturers, notable examples being Panasonic, Sanyo and Goldstar (later known as LG Electronics).

-===== Emulators =====
+As time went on, the 3DO's competitors (the [[systems:psx|PlayStation]] and the [[systems:saturn|Saturn]]) would surpass it in popularity.
+This system scrapes metadata for the ''3do'' group and loads the ''3do'' set from the currently selected theme, if available.
-==== libretro/opera ====
+</WRAP>
-Opera is an open-source, low-level emulator for the 3DO Game Console. Opera is a fork of 4DO, originally a port of 4DO, itself a fork of FreeDO, to libretro. The fork/rename occurred due to the original 4DO project being dormant and to differentiate the project due to new development and focus.

-| 3do.high_resolution   | The default internal resolution is 320x240, but the output resolution is 640x480. This feature makes the system behave as if it has a 640x480 framebuffer.                                                                                         | Enable and set it to 640x480                                                               |
-| 3do.cpu_overclock     | The 3DO used a 12.5MHz ARM60 CPU as its central processor. The emulator has implemented a CPU overclocking feature in the Opera core so that you can increase performance up to 2x. [[https://www.youtube.com/watch?v=7bT2ecwKdHQ|Example video]]  | Set it to 1.5x. May not have an impact on all games.                                       |

+==== Multi-disc games ====
+[[#libretro: Opera|libretro: Opera]] supports multi-disc games, however it does not support loading them from M3U playlists. In past Batocera versions, this required manually renaming the save file to the new disc in order to continue your game.
+From Batocera **v34**, simply enable the **NVRAM STORAGE** option from the advanced system settings (''[SELECT]'' in the game list) for the multi-disc game to allow it to automatically use the same save file. Do note that this shared storage has the real-world limitations of the 3DO's drive space.
