Sonic Adventure Tikal Minigame DLC by PkR

This is the first fully custom event DLC for Sonic Adventure (Dreamcast). It makes use of the game's built-in DLC system to add objects and challenges without hacking the base game, and is set up the same way as official SA1 DLCs. The file can be played on an emulator or on a real Dreamcast console with any version of Sonic Adventure (I only tested on an emulator though).

To play, load SONICADV_515.DCI or SONICADV_515.VMS on your memory card and start the game in Adventure Mode with Sonic. A 100% save file is recommended.
A full VMS dump with a 100% save and the DLC preloaded is also included.
