I had a couple Wisdom Tree Game Boy games as a kid, never knew there was a port of Spiritual Warfare until recently. Excited to find a copy for a not ridiculous asking price!
You can, but you have to add the correct oscillator and associated passive components, or buy the Japan-only Super Game Boy 2 that fixed the issue.
One fun possibility is that if you get it running at the correct clock speed, you can also add the link port back in.
