Megadrive 1 - JAP VA4 not working about megadriveplusplus HOT 14 CLOSED

I got it working. :)

After looking at PAL VA4 instructions for troubleshooting I noticed it was pretty similar enough and had the trace cut on the reset out end so decided I would join the reset in trace back and cut from reset out side but when removing the wire the whole trace lifted not sure if it got damaged when I soldered the wire to it I should have used thinner wire.

Anyway so I found where the trace lead to and soldered reset out to that, rejoined reset in, and already had a cut from the trace lifting and now everything works.

So to sum it up for people in the future on this model try cutting the same way as PAL VA4 picture. Shame VincentNLOBJ does not have it anymore so we could see if it fixes his same issue. Sorry for the lengthy post guys.

This is good news, thanks for reporting back!

Why did you reconnect JP2/3? All JP1/2/3/4 must be cut!

from megadriveplusplus.

I assumed dragoncity scheme white straight lines meant they had to be connected! but that's an easy one, just removed the connection.

Regarding JP2 left contact seems in a pretty bad shape.
Multimeter is dead when testing it against all the other JPs, not sure if it's normal, but it's worth to mention.

UPDATE: I've removed all wires from arduino except for RESET-IN (A1), RESET-OUT(A0), 5V and GND, to test if reset button restart the console normally but it does not.

Curiously enough, if arduino is NOT powered on (disconnect 5V), reset button works.

Did you cut the trace between Reset In and Out?

Try enabling debug messages and check what the serial monitor tells you.

Yeah I did cut the reset in-out trace, following up dragoncity scheme.
When arduino gets 5v, reset button is disabled so unless it is solved that prevents the mod from working.

I'll try out debugging as you have suggested, thanks!

Hey guys I'm having the same exact issue the reset button doesnt do anything. Any ideas?

What does the debugging output say? Can you also check whether the reset button is active-low or not?

It's messy atm will probably tidy it up some more. Also noticed your missing that Surface Mount between in and out dunno if that matters.
