The Sonic Adventure New Year's DLC was a Japan-exclusive piece of downloadable content released by SEGA to commemorate New Year's 1999.


According to Sonic Retro, when active, the DLC would place a traditional kadomatsu in Station Square.[1] The DLC was initially released on December 26th, 1998 and was removed entirely on January 7th, 1999. On December 29th, it received a patch due to a bug that supposedly made the players get stuck at a certain point in Knuckles' story while the DLC was active.[2] The DLC's file size was 66 blocks of memory, with the filename being "SONICADV_001".


The main reason the DLC is so scarce and so hard to find is due to it only existing in Japanese versions of the game and for little time. The DLC remained Japan-exclusive due to different traditions and release dates. The Dreamcast itself and Sonic Adventure were only released in North America the following year, making it impossible to obtain the New Year's 1999 DLC in the U.S.

Due to the use of the kadomatsu decorations, it also could not be reused for later New Year's DLC in the United States, considering Kadomatsu is a Japanese tradition for New Year's.

On November 8th, 2019, a user that is known as Moopthehedgehog on the DCEmulation forums found and dumped the DLC. Moopthehedgehog said he found it on a Japanese 4X memory card that he purchased.[3] It was then ported to the Sonic Adventure Dreamcast DLC mod on PC fully translated to English.
