※Please read the profile section before purchasing. This is a set of a compatible AC adapter that can be used the same way as the AC adapter (Sega SA-190) for Mega Drive 2 and Super 32X.

(Most other sellers' products do not have PSE certification) The specifications are as follows: Compatible models: Mega Drive 2 and Super 32X (other models are not supported) Included items: AC adapter (9V/2A, PSE certified) and plug adapter (All included items are new and have only been tested for operation) How to use: ① Plug the AC adapter into the wall outlet. ② Plug the DC plug of the AC adapter into the DC jack of the Mega Drive 2 or Super 32X. ③ Turn on the Mega Drive 2. (In the case of Super 32X, turn on the Mega Drive or Mega Drive 2 connected to it) ※① and ② do not have to be in order. ※Although the DC plug may physically connect to game consoles other than Mega Drive 2 and Super 32X, please never use it with game consoles other than Mega Drive 2 and Super 32X. The game console may be damaged due to differences in voltage or polarity. Please note that this product can be returned if it does not power on.
