I think there is only 1 reprint of the MD version, but it was sold at two different times with different extras. And these extras were on the side and not inside the packaging. There seems to be 3 Dreamcast versions, US, EU and JP. IDK about digital releases.
The timeline I see for the MD releases is 2011 the initial order. Then the Reprint was in 2011 because the initial sold out so fast. It looks to be just a few months and you can find videos on Youtube of people getting the reprint in 2011. Then people receiving the reprint again in 2015 in the second run of the reprint.
The initial version had 3 different covers, teh Genesis, Mega Drive EU and Mega Drive JP covers. The reprint cover is just the black one with Genesis/MD logos on it and says Watermelon Reprint on the top.
