Technically, these are separate games. The ZX Spectrum has the original Bomberman, aka Eric and the Floaters, the MSX and SG-1000 have Bomberman Special (a remake of the NES game), the NES and GBA have Bomberman (NES version), the X68K and PC Engine have Bomberman (similar to the second game on NES), and the SNES has Super Bomberman.
technicaly, these are 4 diferant games. 1. bakudan otoko (bomb man or eric and the floaters), 2. bomberman(nes game), 3. bomberman/dyna blaster and 4. super bomberman!(snes)
The Pc Engine and Sense ones shouldn't be in there, they're different games and named differently as well. Honestly the original one shouldn't even be in there either since it's not the same version or a port of that version. The non-Eric and the Floaters version for NES onward should be the only versions compared.
