Neo Geo Setup Finally Complete (Mostly)

I finally got my system set up with the configuration I envisioned , which was to have it side by side with my FM Towns and to make use of its nice display , I ended up getting a XNEO-1 RGB/S adaptor that was broken E-waste and with the help of sarduchi who frequents this sub managed to get it repaired , which finally let me use the MultiSync display with the system.

Other than that I also removed the ROM chip and installed a socket with the UniBios 4.0 ROM and I swapped the joystick top with a replacement ball as the old one was cracked which is a common issue , replaced the DC power socket as the old one was rusted and was dropping the voltage , and i gave the cart slots and other contacts a good spray with an off brand Deoxit.

I still do want to get a DA-15 switchbox of some sort for the RGB15 cable so i can toggle between both systems , in addition to that I have an original 2kb memory card which I'm assuming has a flat battery so ill need to open that up and install a low profile battery holder and a new battery and figure out how to close it up again.

But all that's extra I'm just happy that i finally own the system after wanting one for a decade and a half.

Does anyone know how the heck to get a Neo Geo AES to display on a FM Towns Multisync Monitor?

Long story short I've been tearing my hair out trying to get a revision 3-5 aes to play nice with a towns crt , I've tried just about everything to no avail. I recently rigged together a CSYNC to DIN cable but that didn't work.

I also wanted to mention that I did mod CSYNC back into the AES before that with a 75 ohm resistor and 470uf capacitor, later swapped that for 100uf to get it closer to the older model AES systems.

Also got my hands on a broken micomsoft XNEO-1 video box and repaired it , and used that to connect the towns to the crt , since the box provides HV sync as well as CSYNC I tried hooking it up to my NEC multisync as well but that displayed nothing, or with the towns.

I realised it didn't even see if the system was working at that point so I janked up a composite cable , and tried it on my old 2007 Toshiba Regza LCD nothing displayed. I read that the AES had issues with LCDs so decided might as well try a CRT TV , so I grabbed an old Magnavox TV that I had in the garage and on that it did finally display , but its been the only screen that bothered to show me anything.

So what gives and why are Neo Geos such a pain in the ass , is it the 60hz frequency being off or something. I'd appreciate any help.

5v or 9v PSU?

So I've some questions,

Recently i bought a Neo Geo AES 3-5 and from the research I've done it appears to be a 5 volt model , I also got a multicart that I'm waiting to get shipped.

Now as far as I'm aware unless I'm getting it wrong it can be converted into a 9v system with a a handful of components (voltage regulator , inductor , some didoes)

But I'm getting conflicting information on whether it's better to have a 9v system or a 5v system.

Like I know for certain multicarts you want more amps maybe like 5 or 6 amps. But it's the voltage that's left me a bit confused.

Can anyone here clarify what the better option is voltage wise to help multicarts run in a mostly stable way?

Or does it not Matter?
