Title: Super MVS Converter 2 Problems - Graphics Corruption and No Sound
Post by: chadt on April 11, 2012, 12:29:04 AM
Just got a 2011 version converter yesterday from ic2005.com and it's not working.  The graphics are trashed and there is no sound on both of the known working MVS carts I have, Metal Slug 3 and Blazing Star.  A contact from ic2005 says my power supply is too weak but I'm using an english AES system with a 5volt/3amp AC adaptor which is the strongest adapter that SNK made for the home console.  Check out these pics and tell me what you think.

I have the same problem and have 5v/3a. I used an even stronger one 5v/8a and it does the same problems.

It may not be the amount of power available at the plug as much as the amount of power available at the cart port. This is an issue on the PC-Engine for some people, one people have solved by soldering a large wire (say, 20 gauge) from the 5V regulator on the PCB to the 5V supply pin on the cart connector. Some AES motherboards may have a similar issue - the PCB line going to the cart connector may not supply enough current to power both the converter and the cart.

OTOH, the other person who reported the same problems a few days/weeks ealier mentioned that the older revision of the MVS converter works on the same console. So it seems more likely that it's the newer blue converters that are causing the problem.

Maybe... need someone with one to respond, but that goes to a basic issue of customer support - people with no problems (or solved problems) have no need to go back on the forum, so they often don't and so don't see threads like this. I don't have one of these and wouldn't be able to make use of one in any case since I don't have the console or games either. So there's a certain amount of guesswork from some of us more frequent forum members who stick around to help where we can.

I have bought this MVS TO AES and I have two cartridges: 120 n 1 and 111 in 1. Not working any of them! So it is not 100% compatible as said. My neo geo aes is japanish and low serial and 5V 3A power ac. Any ideas why doesnt work? Thanks.
