Neo Bomberman MVS

P3/P4 CPU Players are actually used if you play more than one battle round. You can hack them to be used earlier, but they will be introduced at that point regardless. It appears the HUD showing 3P/4P from the beginning yet not being used in attract or the first round was confusing people. I guess you could consider it to be poor HUD design, or poorly communicated.

There is _no_ code in the game to handle P3/P4 as Human players unfortunately. Attempting to add it in would require extensively hacking the game code, it isn't a switch that has been disabled.

I do now feel a bit like I wasted his time in asking (because nobody had ever even communicated that P3/P4 CPU players were introduced after you play a round against only one) but at least now we have a solid answer to give people.
