NTSC-J Scorcher, anyone know any further details?

The Japanese version of this game seems to be ludicrously rare, as in impossible to even find a copy of let alone afford. It's also the only game on Satakore I've seen without any photos of the game complete, leaving me to wonder if it even existed. Segaretro confirms that it exists as it has a photo of the game complete in box, but has no further details about the Japanese release in particular. Does anyone know any further details on how the game ended up so rare and near impossible to find? Almost feels like it never got a proper release.

Wasn't aware there was a JP version. Haven't seen a version of it before. Are there any advantages or additional modes in the JPN version?

I'm willing to bet the Japanese version of Scorcher is virtually identical to the US and PAL editions, only with some translation or mention of its different publisher... If there were significant differences, surely we'd know about these by now? Then again, it took long enough for "the Doom myth" to be shattered!
