Free Fall Reproduction?

Hello. I am baffled. I am trying to reproduce Free Fall onto a cart. I am using Captain Comic as a donor, and I am also using 2x 27c512 eproms. I have tried 2 different copies of Captain Comic. The Rom was mapper #11, and split into two 64k size files. I did a direct solder in, but on both copies the screen was nothing but garbage on the screen. Any clues on this one? Thank You!

Normally since all this is unlicenced the pinout is compatible with standard EPROMs.

I had this problem when I started making them its probably the CHR ROM. could be a bad connection or a few or that EPROM
I would check my CHR connections then if that failed reprogram the CHR ROM and make sure to check the image to make sure its correct and verify it after programing to make sure its in there right
note:most games will play with scrambled picture if you dont even have a CHR ROM pluged in

i had that problem too, never fixed it. i thought because it was never put on a real cart (i dont think there is a prototype, just a file), it couldnt be reproduced.
