I've wondered about a binary patcher, or at least a patcher that patches on binary load in to memory, like CyberPatcher / OxyPatcher for emulated instructions on '040 / '060 Amigas...Sounds good but I dont know if its possible as data is lost when enterning the fline trap maybe there is a way to do it change fpu instuctions to jumps and insert the nop there and run the trap. But I don't know how to go about it as yet.
That's how CyberPatcher works - patch with a jump, run soft-float, return. It's much faster than exceptions.
