Actually, functionality is the same for all the games minus Seibu Cup Soccer (has an earlier revision of the COP ROM, unknown purpose as per now). The only real differences between Legionnaire and Raiden 2 HWs functionality so far known is the endianess of some commands, but that's mainly because of the different CPU used (m68k vs. i86) and some ports are shuffled around via a PAL, in a clear attempt to not allow exchanging/upgrading of the boards.
