You cannot flash just the 118 kB rom with Mysamba. It seems to need a full 128 kB file. You can create a full 128 kB file by concatenating the rom bin file with the various flash regions, which you can create with the emulator. The process is discussed in the manual, summarized as follows:
Open DOS window
change directory to where your files are
copy /b wp34s.bin+wp34s-1.dat+wp34s-2.dat+wp34s-3.dat+wp34s-4.dat+wp34s-5.dat+wp34s-6.dat+wp34s-7.dat+wp34s-8.dat+wp34s.dat wp34s128.bin
Then load the wp34s128.bin file into the calcualtor with Mysamba.
You can use the same flash region over and over if you want, and they don't have to have any programs in them. The above is for a rom size of 118kB; the size changes occasionally as flash regions are consumed or freed up by changes. The wp34s-1, -2 etc. flash files are 1 kB each, the wp34s.dat file is 2 kB, just make sure to add enough flash region files with the 2kB file at the end to make the whole file 128 kB.
