UPDATE on the power glitch issue. As has been posted since the multi has been making it's way into your pcbs, some motherboard have been found generate some power problems that can be easily solved by adjusting the voltage level. Although we tested many motherboard revisions during the design and test phases, we didn't encounter this problem until some users reported it.
If someone for whatever reason doesn't want or can't adjust the power on their cabinet and only has a MV1F or MV1FS motherboards, then they should apply the solution that we post below, which consists of cutting a trace close to the cart edge. See picture attached. Do NOT remove the resistor connected above the cut point. It is necessary to the function of the cart.
The problem comes from the position of the trace in relation to the FPGA. Though it is on a different layer of the pcb and not directly connected to any traces entering the FPGA there is interference that messes with the function of the FPGA on a certain line. The software solution we tried seemed to work HOWEVER, without going into too much technical detail, there is a chance that if the intereference is TOO Big, the firmware solution could potentially cause damage to the FPGA, especially if someone ran their voltage too high for a period of time. Therefore it became obvious that this is the best solution even if it is inconvenient.
This solution consists of opening the cart VERY CAREFULLY PAYING A LOT OF ATTENTION TO THE MicroSD Slot and cut the trace indicated in the pic below.
Take note that the SD card slot slides into the side of the cart shell therefore you need to take care not to exert too much upward pressure or the slot can be snapped of the cart pcb. If you damage the sd card slot it can be replaced but it will not be a free repair. So take this into consideration when deciding to do the fix yourself.
If you don't feel like you can do it, you can send the cart to us and we'll do the fix and send back to you.
It took a long time to pinpoint the problem and then research the best solution. For that we are sorry. We are just a few people in different parts of the world trying to iron out any issues. Obviously we will be doing all mods to the carts for free. Send it too us and it will get fixed. Mitsu has agreed to take on all carts sent his way in order to help me and to take care of you guys.
Please PM either Mitsurugi (USA) or Darksoft (Europe) depending on your location.
Thanks!
