Control inputs go through the RC networks, into the Neo C1 chip.
Thanks.
NEO-C1 chip faulty.
Joystick - jamma LEFT and UP pin indicates several NEO-C1 also foot-circuiting.
Tomorrow exchanged C1 chip.
Did you first check if the resistor network was faulty? It's a common problem. Check the resistance between VCC(Pin 1) and the rest of the pins. Should be something like 1k, 1.2k, 1k, 1.2K, 1k, 1.2k, GND.
Thank you, yes, I checked it last night.
RC1 = 5v, 0.323k, 0.212k, 1k, 1.2k, 0.323k, 0.212k, 1k, 1.2k, GND.
I changed RC1 members, but there is no change.
It continues to blame.
What could be more wrong?
NEO-C1 chip?
If there is multiple value changes like that and replacing it doesn't fix anything then it's sadly the C1 itself.
I understand, exchange chip C1
You're lucky the C1 is on a lot of Neo boards. If you used MV1C, the YSA2 controls those signals and you can only get them from other MV1Cs.
C1 chip was exchanged, but the problem has not been solved.
CR block was defective.
Where can you take such a thing? Ebay?
B1 CR10-A-026 348
I thought you swapped it out? f you need some I have some.
Thanks.All. WRAM = Work RAM aka 68K RAM and BRAM = Backup RAM.
Is it me... or has neogeohu... moved from that silly NG X thing to having more tech problems than Win 10?
Just an observation...

What is the problem?
I bother you?
CPU>Bios>WRAM>BRAM
I checked the BIOS and addressing of outgoing data.
Results:
Address: 0xffff
Data: 0xffff
I think the bios can not boot.
