The games on this ROM appear to be built together, i.e. they cannot be completely separated from each other like most multicarts. Out of curiosity though, I messed with a debugger and found code to make the menu automatically load into each game:
Address line #1DEA0:
first two bytes to ff = hanuman quiz game
first four bytes to ff = malaria
first six bytes to ff = hanuman typing game
As such, I was able to get them into separate ROMs, but not in the conventional method as most multicart extracts. Additionally, I was able to trim Malaria into a smaller 40k file.
