New to the forums (thanks for the add by the way) and this is my first post. A while back I found a Neo-Geo conversion cab locally on craigslist for $120. The seller could not get it to load either of the carts he had. It only brought up the green jumbled graphics screen as the game loads but it would freeze there. They had no idea on how to fix it so they were selling it cheap. Someone (way back when) had taken an old Williams Defender cabinet and used a Neo-Geo conversion kit. I know this because the cabinet still had the paper work for Defender inside as well as the SNK paperwork. I have spent some time refurbishing various parts of the machine to get it working properly. It came with 2 carts, Windjammers and Aero Fighters 2 and had an MV-1FZ board inside. After cleaning all of the contacts I was able to get both carts working though I still needed to replace the button switches as well as cleaning the buttons themselves. Everything was so filthy the buttons would stick. Soon after installing replacements and getting everything cleaned up I was up and running. I ended up getting an MV-1C because it seemed like some of the sound caps were starting to go out on the MV-1FZ and I don't trust myself when it comes to soldering such things. The MV-1C came from China and works without issue. After that I recently purchased a 161 in 1 multi cart off of ebay from a seller that has stock here in the US. I was super pumped when it arrived but extremely disappointed when I tried to use the cart. It loads into the menu just fine but when I try to load a game 80% of the games load into the system test menu where you have the grid screen and cycle through the various screens with the 1player start button. Of the games that do load every last one of them has graphical issues vertical streaking and of those at least half have extremely bad sound clipping... to the point where you cant here anything over the cracking popping and clipping.
I know it's a long preamble to my question but I want to give as much information as possible.
My questions are... Do I need some version of the unibios to run the 161 in 1 cart?
Did I just get a bad multi cart?
If it is a bad 161 in 1 should I just try to get another?
Is there something I can do to fix the issue so this will work as intended?
I have done some research on which version of the 161 in 1 I have and as it turns out I have the V4 board. I have posted a youtube video showing what is going on. Here below is the link...
