Hi there.
I have a Saturn Model 1 VA0 PAL console here with an interesting problem quite similar to the thread created by Eidolon_NG.
The control ports presumed to have an issue with power output to the pins.
Capacitors for CE47,CE48 have been replaced.
Here is a summary of a few tests using 3 devices in a single port configuration.
Standard digital only controller third party
Both ports -ok
Test -ok
Official 3D Knights controller black
both ports -bad, negative function, not detected
X\O mode -bad, negative function, not detected
Action replay 4Mplus -menu infinite loop observed
Test bad
Brook Wingman SD adapter.
Both ports -Status LED varied intensity (port#1/#2),
Button on adapter needed to be held to see very dim LED
Device not initialized, negative function, not detected
Test bad
External power applied to the adapter via usb/pc port
Device init -ok
X\O mode -ok
Slow and intrusive analog stick drift (up direction) observed
Action replay 4Mplus -menu infinite loop observed
Certain games 'burning rangers' exhibit random inputs, unplayable
Test bad
In all instances where the AR4M+ menu was sent into a loop, disconnecting all controllers, and reconnecting the digital only controller to port #1 was the only means to end the loop and stop the madness of potential random inputs.
I did test the console in 2 port configuration, very mixed results with similar conclusion.
I highly suspect the issue could be the row of resistors? connected to the pins for each port.
Any insights alternatives and specifications of these little dark magic boxes would be much appreciated.
The only advice I've been given so far is a replacement board, which would mean trashing a 99% working VA0 board entirely.
Thanks for any assistance guys
have a good one
