As the title suggests, my conversion cart is missing the background when I get to stage 4 does anyone else have this problem?
I'm wondering if it's a possible bad ROM dump or if I should open up the cart and see if there's any bad solder joints.

This was common in the early batches of repro carts out of China. It requires a different pal chip and the addition of some jumper wires. Best to get in touch with the seller if possible or check out Arcade Projects forum. They have info on this issue.

Thanks for the info. I reached out to the seller and I'll report back with what I find.
