I looked at the ROMs... The problem is that these are bankswitched 
carts, so the S-Record files are using 24-bit addressing with the top 8 
bits specifying a bank number. At first glance, it appears they're in 
the same ordering used for the .a78 format, so it shouldn't be hard to 
convert it to that. I'll throw together a converter for srec->a78 after 
I get the disassembler I'm working on out.
