Irony multiplied:
Both systems (MSX and DC) are officially dead, but the communities around them are quite active.

Guaripolo (Gabriel Cabral) and Baig (Jorge Cabral) have released an Alpha 1 version of this port.

It's not much yet.. Some comments from the authors:
Among what you can NOT expect:

* The game is NOT presentation (on grounds of saving memory).
* The game is NOT music (but if they are).
* Controls are configured (accelerates with X)
* I do not remember if they are configured for the player 2

Seems you need the original data files as well.

anyway, I thought it was worth a mention here

Heh, looks like a port of our RoadFighter remake from 2003, but with modified (ugly) gfx. Wonder if they credited us and would be willing to add their changes to the code to the official remake properly
