Modifying a mod depending on closed source mod

[hoho]

I'm a complete noob when it comes to MC modding but I'd consider myself good enough coder in general.

Today, just for fun, I tried to port HungerOverhaul to 1.6.4 and got a (small?) problem. The mod has full source available but depends on Pam's harvest craft and that one doesn't have either source or API. I've tried all sorts of things I could come up with to no result.

Initially I just added as an external lib (to get HC to compile) + added to mcp/jars/mods->

I've tested HC with the same forge version as I'm using for developing and it loads up just fine. I guess it's erroring as it assumes obfuscated MC?

Next I tried to decompile it with both but it gets decompiled jd-gui and fernflower included in MCP but both caused HC to have a ton of problems as it was using obfuscated MC names. I tried to run BON and deobfuscate to srg but that didn't seem to help at all.

So, anyone has any idea how I might get it working?

Use BON's "deobfuscate mod" option to get it to MCP names and then add it as a library.
