Adding new I2C bus command

I need to read / write an catridge which is apparantly set to respond to an unusual I2C bus command.
Is there a may to test this out quickly without having to hack the source code, install linux, rebuild the hacked source, and test ?
N.B. The catridge is a 64K CAMPAC with a protocol tranlating micro controller hidding a 24L64. It responds to:-
%00<A12..A8><R/W>% %<A7..A0>%
instead of the usual (for a 24L64) of :-
%0101<CS2..CS0><R/W>% %000<A12..A8>% %<A7..A0>%
Where CS2..CS0 match the chip select pins, A12..A0 are the address, and <R/W>
