Attention, there are instead referred to in the description on Amazon 2 AAA batteries / accumulators actually 4 AAA batteries / accumulators per controller required!
NOTE 2: In mode the PS1 PS2 there are problems a PS1 memory card in Slot 1 of the PS2 can no longer use when plugged in the controller connector including the radio receiver of the controller. Use a PS1 memory card in slot 2 is also by disrupting the receiver and controller in certain menus (loading, saving, possibly new game start) lose connection and these would not be easily restored. Depending on the PS1 game, it is sometimes easier, sometimes harder to convey the desired keystroke. For example, in the PS1 game "Resident Evil" (German version), it is sufficient that the controller analog Press the key to until the light goes out on the controller, then normal operation is again possible. At PS1 game "Medievil" (German), however, the analog button of the controller must be pressed along with the desired key, probably because only very briefly is a connection to conditions. In the games themselves so far no problems have been noted only in conjunction with the load / store functions or menus. Tested with PS2 model SCPH-77004 and a new PS1 Noname memory card, the PS2 is compatible, or an original Sony PS1 memory card SCPH-1020th Further details are still unclear about whether problems with a PS1 memory card in slot 2 and a 2.Funkkontroller occur or similar. Has taken me this is not so bothered, because with a little practice can save and load and occurred in the PS1 games themselves, as it is written, no problems. In PS2 mode there was nothing flashy.
