Recently, I decided to pickup a PC Engine CD-ROM Unit + Interface Unit; as I have been wanting many CD titles. When I bought it, I assumed it would use the PC Engine's adapter. However, I found out that the PC Engine's adapter doesn't even fit into the interface unit's AC port. I need some help finding out what kind of adapter I need to buy for it, and also if I need to get any modifications done to it. I can't find many details about the required adapter, so any help/advice would be greatly appreciated, thanks.
