Dec 1998
SRB1 Christmas (also known as Sonic Xmas Blast) was released in December 1998, during the period between the end of SRB2 TGF's development and the release of SRB2 Halloween a year later, as it was clear by then SRB2 would no longer be using this engine. It is largely a repackaging of SRB2 TGF's existing levels with Christmas-themed names and a winter theme applied. The ability to save the game was not present however, and the game itself would start immediately on load.
