24khz help needed NAC Gradius IV

[hoagtech]

I can’t seem to get Gradius to display properly in 24 kHz.

Does my New Astro City not auto switch to 24 kHz?

The game works fine but is small in 15 kHz.

If. It can anyone share the plug location on the chassis?

Right on thanks Mrhide.

Nope will not work, better send Gradius to me instead

some MS9 are automatic switching with a relay, but I think the manual version with a jumper wire is more common especially in NAC

unless you purchased a cab new, NEVER assume the guts match the manual.
as an ex-arcade engineer i can tell you that shit gets swapped all the time - the only rule is/was "get it running as fast as possible"
