Post edited: I made these custom cards for my friend with a JP a while ago, but I based them off the Williams/Bally size, and I guess that doesn't fit Data East. Thanks to RussMyers I fixed the size (and ChadH helped with a rule fix) so these are good to go now so I can share.

(Edit: Too lazy to fix preview, but there's a typo in the text, it's been fixed in the PDF.)
