1) You must replace the 7805 voltage regulator(s) inside your Sega CD, you fried them when you used the NES AC adapter. Never use a NES power supply with anything but a NES, they break everything. The voltage regulator is a IC with 3 pins, usually screwed onto a heat sync. These cost about US$0.30-1.00. Most likely you will need to replace only 1. Alternatively, you could have broken a fuse (if one exists.) Maybe you should have a professional look at it. 2) You probably need a new 72-pin cartridge connector for your NES.
You could try using contact cleaning spray for your NES, my NES (well, one of 4 ) had a dodgy cartridge connector - though not as bad as no sprites showing up - but after taking the nes apart, spraying the edge connector and 'cleaning' it by inserting and removing a cart a few times, it works as new again. Never get the flashing power button again :smt023
Er...uh...is that just the official NES AC adapter...as I'm using a universal 9V AC adapter that works on both Sega CD and NES...as I don't have an official Sega CD adapter...and my NES one was stolen a few years ago by my brother...though the adapter always stays plugged into NES...as I never use Sega CD. Er...Is the official NES adapter that bad????
well, I dont know about the JP/US units, but the PAL NES uses 9V AC whereas the MCD/MD/GG/SMS use 9/10v DC.
Yes, the NES is AC and I believe has the wrong polarity. MAYBE, the Sega CD has a center-positive plug, I know for sure that Mega CD (1) has the 9vDC center-negative Japanese console standard.
