the version of Puzzle & Action (I believe its actually Ichidant-R) which

was credited to SpainDumps in the included text file. This appears to be

a bad dump (half sized roms) however the roms do not match up exactly with

the good dump of the game. English language sets are assumed to be the

Japanese Language versions of Borench (if of course these games were
