US, JP, and Led Storm version seem to be the exact same, the only difference being the languaje on some texts and the title. Unless there is a difference in gameplay I'm not noticing, I don't see why there are 3 separate categories for each version.

Led Storm Rally 2011 is the only one that is different, as the gameplay changes a lot.

Mod edit/info:

USA region info added.

There are some prototype of the game that were designed/created before the official versions. It is ok to put all these 4 versions in different sub-categories. Recommended at the very beginning of the runs you can show the versions of the roms for future attempts, even though it is easy to notice.
