I downloaded the official VMI file from here https://web.archive.org/web/20070331081 ... cas.ne.jp/ , took the circulating VMS, renamed it to match the VMI, opened the combo with VMIwriter and got... an error message: according to the VMI the game should be 12126 Bytes in size, but the actual filesize is only 11776 Bytes.
To sum it up, all available copies of "Beam Force" including the ones on BlueSwirl, Dreamcast Live and the Dream Explorer/VMU Tool CD are corrupted and obviously haven't been uploaded fully back in the day. So, unless someone comes around with a fresh dump of the minigame, this one kinda seems to be lost forever...
