As requested by @MetalliC and others. I'm opening this section.
Here is what we need.
There is always chances origin EPROM not 100% good, because IC22 is not CRC protected, so we needed photo of ROM TEST screen from some other cart to be sure.
This is needed for GGX game and also for "World Series 99". If you have one of these carts, please show the results of your ROM TEST to find out if it same/different from dumped "Super Major League 99"
