The Sega ID for this version is SEGA-PC175-EX, but on the disc it's is still SEGA-PC175.
The game is a Windows, MacOS and Linux hybrid.
The mastering codes are
R<tab>arvato 56568024/SEGA-PC175 D 21
R<tab>arvato 56568025/SEGA-PC175 DP 21
and I believe layer 0 is the DP one and layer 1 is the D one. DP is furthest from the spindle hole.
The mastering SID codes have a space between LP and 73 (LP 73). I don't know why, but it clearly does.
