Specifically for the E4 sampler, its preset data is co-mingled with the sample part of the flash. In a typical sound ROM layout, E-MU organized the data into two segments: the preset data used by Proteus 2000 and its variants (P2K) and the sample data used by P2K and the EOS samplers (E4). Like the originals, these sticks store a maximum of 32Mb of sample data. If your E-MU device uses these sound ROMs natively, these clones will behave identically. With a little bit of determination, I have succeeded reproducing hardware clones of the E-MU expansion sound ROM SIMMs used in a wide range of their devices.
