Jan 22, 1999A near-final Japanese build.

PlayStation Underground Jampack: Winter '99#

It has only the first level, albeit not the whole thing (it fades out near the end), but it's based on a slightly earlier build than the final and has a few differences, though not very many.

Demo	Final

The logo is green with yellow and white text, and NEW GAME and MENU are more spaced out. The logo's filename is TI_US.TIM.

Euro Demo 50#

The demo included in Euro Demo 50 is a 2-player match against Lammy and Rammy in the second level of the game. Like the other demo, not much is different besides the title screen.

Demo	Final

This demo has a unique yellow logo, with the filename TI_EU.TIM.
