depends
for this one they replace the protection chip with an FPGA and instead of real time decryption they fetch pre-decrypted data from a previously unused area of the ROM (but otherwise don't modify the game code)
for the Atomiswave bootlegs apparently most of them were made from a faulty copy of the game (or earlier faulty bootleg) so there are corrupt backgrounds and frames of animation in a lot of them.
some of the NeoGeo ones have weird access timing causing even more glitches and slowdowns than the system already had (also with Garou the majority are based off a hacked version of the prototype as there's no final version without encryption and custom banking)
in other cases the bootlegs are unauthorized extra cartridges produced at exactly the same time as the originals to the same standards.
