Does the Usamune practice ROM work on the ED64 Plus flash cart?

If you have it try it, id assume so, but I'm not an expert.

I don't have one, that's why I'm asking. If Usamune doesn't work on it, I'll get an Everdrive

I have one, it works perfect. You just need of course the expansion pack for your n64

Perfect! Thank you. I have an expansion pack

Alright, have fun
