  1. I’m using a freshly downloaded Pokemon ruby rom to get patched with Pokemon Jupiter (a ruby hack), but it keeps failing. What might be the issue assuming I’m using multipacher correctly?

    • Hey there Garyle, thanks for coming here. Check your Ruby rom version, some rom hacks requires V1.0 rom version for patching and I guess that’s in the case with Pokemon Jupiter. You might have Ruby V1.1.
