To be more clear:
those PSU should deliver +10V and at least +5.5V, the voltages will be regulated in the NeoGeoCD again.
Using a +12V and +5V is simple not fitting that well IMO, +12V are too high (causes extra heat in the console) and 5V aren't really enough.
It can work, but it can also cause extra stress on the components.
Repairing/swapping caps on original PSUs and using a AC converter 230V -> 115V for EU is a viable alternative.
None of the solutions are cheap, thats the thing about NeoGeo home consoles.
Edit:
what makes these hard to find replacement for is not the dual output, that can be replaced very cheap:
LM2596 cost 1-2 bucks, add a good 12V PSU, few wires and you're good..
the "unobtainium" is the power plug on the NG CD, one would have to print them and then fit plugs
if you have the power plug, then there is IMO better ways to replace the PSU if you don't mind a bit of soldering
Hi, I already try with a stepdown converter I use the xl4015, but was the same result, just black screen.. I went ahead and take some measurements in both consoles with the generic and orignal AC adapter..
I Measure the voltage regulators too, the NEC 24M08 and the 7805 input and output.
And this are the results:

RESULT WORKS GREAT!

Sorry if this is a little confusing, but as you can see, the output from the voltage regulators delivers the correct voltage using either the original and generic adaptors. Im just a noob thats why Im not sure why is working that way.. I only found this thread and follow instructions of OP as a viable solution to my problem..
About the plug , that wasnt a problem, I made mine, I made a mold, put some wires inside and then cast some hot glue, the connector never gets too hot to melt the hot glue, I even cant detect any heat at all in the plug, so it works great.. Im sure there are other better ways and materials but thats what I had at hand..
"if you have the power plug, then there is IMO better ways to replace the PSU if you don't mind a bit of soldering". I dont mind to solder, if you can share how to make a better PSU, that would be great!...
Thanks...
