So from my little big of digging, I found out this:
"An IFS file is an interactive document generated by InfoSlips, an e-billing program used for sending financial documents to customers. ... NOTE: IFS files can be viewed with the free InfoSlips Viewer program or in a web browser using InfoSlips Online."
So something's up. That, or you misread the file extension? Make sure to double check, see if it's correct and all.
"NintenDON'T sue me please haha"
Hi there. So the file says .sfc but when extracted its .ifs or something
