U16 ,a Jump wire

Maybe you need to connect D9 and D10 between arduino pro mini and usb host shield , and max_rst pin of usb host shield need to connect to high voltage, at least I tried it ,if you don't connect them, the hardware can't work . 5v 16m arduino works well.
This is my design, It works with ossc and capture card, but it doesn't work with Blastcity. If the problem can be solved, I'll share the project, thanks : )
I tried to repair the menu of DOJBL rom ,and the rom works in mame fine. However , the rom doesn't work on kovsh cart.
Here is the rom:
