Ganache forking applies _historic mainnet_ hardfork rules to unknown chains.

[davidmurdoch]

It should probably default to the latest known mainnet hardfork for all blocks.

I am able to fork it and use it to deploy my own contracts to it, but while attempting to hit a contract on arbitrum (not in my truffle project), I’m getting Error: VM Exception while processing transaction: invalid opcode.

Thanks for creating this @davidmurdoch! Please ping me if you or @MicaiahReid end up working on this so I can see how this works.

Might want to add a chain history file that may include a genesis file to tell Ganache what to apply to the fork. This may also be addressed in Ganache plugins, but would be nice to be able to do it from Ganache proper.
