from the user manual:

"In order to enable Lock-On emulation, you must provide the uncompressed Sonic 
& Knuckles ROM image (not included) and put it as “sk.bin” in the 
“/genplus/lock-on/” directory, on your default FAT device. In order to 
properly run Sonic the Hedgehog 2 with Lock-On technology, you also need to 
provide the extra chip (UPMEM) ROM image and put it as “sk2chip.bin”, in 
the same directory."

In short, for Sonic 2 only, you need an extra ROM (which can not run alone and 
contains some specific data for Sonic 2 Knuckle adaptation) generally referred 
as Sonic 2K UPMEM ROM.

Also, you do not load the S&K ROM but the ROM that you want to be locked on, 
S&K ROM (and extra ROM if needed) are automatically loaded providing they are 
properly named in the proper lock-on directory.
