I saw on Romhacking.net there was an update to the Super Mario World hack from years ago. I downloaded the IPS file and applied the hack and everything seems to work fine in FCEUX, but gives me an Error: A0 Unknown ROM format with the Everdrive. Anyone else having this problem?

Here's the link to the IPS file for those interested. https://www.romhacking.net/hacks/3467/

More than likely an unsupported mapper issue.

I have an old version of the ROM I got back in 2002. That works fine, but the "improvement" patch breaks it for the N8.

Edit:

Can somebody try this patch linked above and see if the N8 will run it?

This problem related to ROM header. Cart will throw such error if regular ines header is not found
