Ready 2 Rumble Boxing Dreamcast Disc Variants

[segaomega21]

Today I found a copy of Ready to Rumble Boxing at a thrift store thinking it was round 2 since I already had the first one loose disc as well. But when I got home it turns out they are both the same game just different colored discs. If someone could explain that would be awesome, thanks!

I can't figure out how to attach the picture I took so I guess I'll just describe it by saying on disc is yellow, and the other is Red but they are both the same game, and neither one says sega all stars.

The original print didn't work, it froze at the copyright screen. Midway recalled that version and re-released it with a different-colored disc, which had "Hot! New!" printed (or in a sticker) on the front cover.

interesting so one of my copies doesn't even work? I haven't tested either of them. Do you know which colored disc was recalled? I don't have the cases for either one so I can't tell unless i dust off the old Dreamcast.
