Hi man. Would there be another update to the Yo-Kai Watch 4 project? Thank you very, very much for the YW1, I enjoyed it in a incredible way. God bless, stay in touch!!!
Here's your Yu-Gi-Oh Saikyou Card Battle (English Patch 2021) translation. I've made it into an xdelta patch. I used CRC32: 9239D125 for the original .CIA, with your patched one, to create the patch.
I don't have a wii u anymore to test it myself, but if homebrews are not visible on the wii u menu I think you can press L + R + minus to open the plugin menu, there should be an option called "homebrews on wii u menu" or something similar
Or when your player dies, you can say in code, if enemy exists, do nothing, but if enemy does not exist, then create enemy at certain spot. (This would be a pain tho for lots of emeies)
