[RetroArch/BizHawk] Port 1 controls Players 1/3/4 even if no multitap present in any of ports in Mega Bomberman #547

Connecting Teamplayer/4WayPlay in port 2 doesn't change anything. Inputs from Port 3 and 4 is ignored. This issue makes Battle Mode with more than 2 player unplayable.

It's occurring in both USA and Europe versions

Version: RetroArch 1.17.0 (Core v1.7.4 667158b) BizHawk 2.9.1 Can be reproduced with default config Seems to be doesn't occur in other games

It works fine for me with "Port 1 controls" -> "Device Type" set to "MD Joypad 3 Button + Teamplayer" which emulates Sega TeamPlayer in Mega Drive input port #1 and is what the game expects for multiplayer configuration: each player is controlled independently

With default Controls settings i.e "Port 1 controls" -> "Device Type" and "Port 2 controls" -> "Device Type" both set to "MD Joypad 3 Button", multitap is not emulated and, in this case, the game makes player #1 controls the remaining players if you select a batlle with more than 2 manual players (you need to select "COM" for players that you want to be controlled by computer, "MAN" means player is controlled by control pad).

Game expect multitap in any port, it just needs to be reset in order to apply changes. My bad.
