Patching Comic Code? It was quite a while ago unfortunately, so I don't have the exact commands available, but I used their Font Patcher tool in order to do so.

From what I recall, the tricky thing was actually getting the dependencies it required to be installed properly, Font Forge would be up and running but then the script's errors indicated that it couldn't resolve all of the necessary dependencies. Not sure what OS you're on so your mileage may vary - but for Linux they now have an AppImage that looks to contain everything it needs, and for macOS/Windows if you have Docker available there also appears to be a pre-built container for it. There's also quite a few examples that I don't think were there when I used it, since I also recall not being 100% sure of what flags were needed to run it
