I got it, thanks to @djsheep for informing me of this - works for me really well- I run CPS1, CPS2, NAOMI2, Fever SOS and various other single board arcade PCBs.
1. No need for Sun PSU for my Naomis now.
2. Cables and box are well made - professionally done.
3. Everything else.
4. One stop shop for cables and all.
None to report at the moment.
I will later try with the Namco 246/256.
P.S. I dont know about electrical stuff and I will leave it for someone else to do all the tests.
P.S.S. Also whats the 9pin din to AVmulti cable? Seems useless to me.
For SONY's display equipment.
AVmulti contains RGBS signals, one of the interfaces of RGB.
