Hi,
I have programmed a monitor test tool with 11 test patterns for adjusting your CRT to get the optimal picture out of your Neo Geo system. The tool is inspired by the "240p test suite" (JunkerHQ.net) and offers the most important patterns of it. All patterns have been adapted to the color and geometry specifics of the Neo Geo hardware.
I made this tool as a little side-project for myself because my Sony PVM didn't have any test patterns. Also, I wanted to find out which RGB255 colors the system is able to display (because it has only 63 RGB levels). I think it could be useful for CRT owners and for CMVS builders who want to test their setup. I am open for suggestions if there are any useful test patterns missing.
The tool is available for Neo Geo CD, MVS and AES. You can download it from my website:

The easiest way is to burn it on a 700MB CD-R and load it on your Neo Geo CD.
For the MVS/AES cart systems it is a bit more complicated because there is still no flash cart available for the public. You will need 3 x M27C800 EPROMs, a programmer for it and a SAC cart. I am using a SamSho 1 cart with PROGGSC and CHA42G-3B boards. Desolder the P1, C1 and C2 chips and replace them with the programmed M27C800 EPROMs.
Here is a short video of the tool on Youtube:
