Neo Geo AES / Neo Geo CD

All NeoGeo home systems output RGB without any modification, but there are mods available to improve the output. Please read on for more information:

Both the Neo Geo and NGCD use similar RGB cables, with the only difference being the audio connections; Unfortunately, the multi-out on the back of the Neo Geo systems only provides mono audio, so much like the original Genesis, it's recommended that you get an RGB cable that pulls audio from the separate outputs:

RGB Cables:
SNK Neo Geo AES Stereo RGB Scart Cable  (UK Seller)
SNK Neo Geo AES Stereo RGB Scart Cable  / Upgrade to coax cable  (US Seller)


SNK Neo Geo CD & CDZ Stereo RGB Scart Cable (UK Seller)


Mono RGB SCART Cable for all Neo Geo consoles  (UK Seller)
Mono RGB SCART Cable for all Neo Geo consoles  Upgrade to coax cable  (US Seller)

 

Neo Geo AES
Different revision Neo Geo AES systems output different quality video.  Ones with a serial number between 20,000 and 33,000 output the highest quality RGB. This site has excellent information, as well as explanations and pictures that describe everything:

I'll soon be selling an AES RGB-bypass board that allows any Neo Geo system to output the highest-possible RGB video! Please check back soon for more information!

 

Neo Geo CD
The NGCD systems all output excellent quality RGB video, since they use a more updated Sony CXA chip (1645P) and they used all the suggested parts around it with correct values. No bypass is necessary for excellent output, however NGCD systems require a mod to get csync from the multi-out. Please click here for more info: NGCD csync mod

Other NGCD Notes:

- It's common for both the laser and motor to wear out.  I purchased a kit that has both and it works perfect.  Here's a link, but check out the other parts they have for sale, in case you only need one:  http://gamedoctorhk.com/index.php?main_page=product_info&cPath=72_22_113&products_id=2067

- There's a list of CD load times posted online, if anyone wants a reference.  I found my NGCD to actually load faster, but I have a brand new CDROM drive in it, so maybe that helps?  http://www.egameaddiction.com/neogeocd/loadtimes.html

- There's also a monitor test disc available for anyone looking to test their NGCD: http://www.retrorgb.com/NGCD_Monitor_Test.zip
