Please tell me if you know.

I would like to convert to "HYPER STREET FIGHTER 2" using the board of revision 7,
GFX ROM and Q sound rom has 8 mega.
11, 13, 15,17,19 exist.
12, 14, 16, 18, 20 do not exist.
What is the model number of the UVEPROM that corresponds to the 8 mega ROM?
I have 27c322 but this is 4096kb, right?
Do you split the data?
For example, do you divide 13 into 2 to make 14?

Another question is .
There are two "HYPER STREET FIGHTER 2"
① Black board (A + B),
② Separate board (B only)
Do they both use a same rom?
