Need help with a weird problem.
My MC Cthulu + SparkCE +RJ45 drops connection for a split second (enough to display a "joystick disconnected" message) when I move/tap the joystick down. All other directions work... happens about 50% of the time, not all the time, and only when down is triggered.
It only happens on PS2. PS3, PC, NES and SNES all work fine... I am using a Neutrik jack RJ45 mod and cables... PC/PS3 is using the USB port in the MC Cthulu.
I tested the PSX RJ45 cable with a multimeter for continuity and all the contacts work. I gave the Spark it's own dedicated voltage line (messy) off the spare controller port and then it works perfect. Swapping out the spark for regular microswitches gets it working fine too.
My guess is that the controller port can't provide enough juice for the MC Cthulu and the Spark CE at the same time.... but why would only pressing down cause it??? If anyone could enlighten me it would be much appreciated...
P.S. Triple checked wiring, solder joints, checked MC Cthulu and PSX RJ45 cable for shorts, tried both versions of the 2.3 firmware.
