Basically yes. Or you solder a few wires on top of the chip pins.

Note that my suggestion does not perform flash emulation like the
dongle, it only provides a way to write chips with an external
programmer. Due to that, the PLCC adapters make it easier to connect to
the pins of the chip socket (if there is a socket), but you'll have to
stack a reverse adapter on top which has a flash chip inside. Or you use
a top-hat style adapter and plug the PLCC adapter in it. The common
requirement is to keep the flash chip attached to the board in a way
that allows booting.
