nope. lynx headerless rom *CANNOT* be loaded, for the simple reason that different carts use different PCBs that need to be loaded differently.
I'm sure that you managed to load the game(s) you are interested in, but other games will fail and thus your changes cannot be accepted. The only way to really support headerless roms would be to hardcode a database of CRCs of all headerless roms, and it is not going to be accepted
The fault of this whole situation is of no-intro guys who do not explain properly that headerless roms are useless for lynx as well as for nes.
Sorry to disappoint you, but you can only go through adding back the headers or to use softlist.
