-Here's the schematic ​for the S-video mod.  This will work Neo Geo AES systems as well as any other console that uses the chroma encoders CXA1145 or  MB3514. ​ I find the output was a little better when both signals had 33ohm resistors at the output. ​ Play around with these values until you find what's suitable for you.  +[[https://​console5.com/​wiki/​CXA1145|Here'​s ​all the info you need]] ​for the S-video mod.  This will work Neo Geo AES systems as well as any other console that uses the chroma encoders CXA1145 or  MB3514. ​ I find the output was a little better when both signals had 33ohm resistors at the output. ​ Play around with these values until you find what's suitable for you.

 The MB3514 exists in TSOP form factor and can be found on the Model 2 of the Genesis. I have three Mega Drive 2 (Asian PAL Edition Model MK-1631-07) and they all have the MB3514 video encoder. The MB3514 exists in TSOP form factor and can be found on the Model 2 of the Genesis.
