I managed to find several Nanjing games. So I took some pictures of the PCBs.

This game I couldn't find any information on, so I'm not sure if it's 2MB in size.

This is the most information I could find for these games.
Naruto
GLT7256L08-15J3-----------3.3V 32K x 8 Bit CMOS STATIC RAM
0026 BHYFS
MB8464A-10L---------------CMOS 64K-Bit Low Power SRAM
5403 M63
0114 1-1
MT28F016S5VG-9A-----------2 MEG x 8 SMART 5 EVEN-SECTORED FLASH MEMORY
Samurai Spirits 2
CXK5864CM-10LL------------8,192-word x 8-bit High Speed CMOS Static RAM
441H59YY
481F16M-------------------?????
D5122*
Chip with no #------------?????
King of Fighters R2
LC3664BML-10--------------64K SRAM
3CU0
TC55328J-25---------------32,768 WORD X 8 BIT CMOS STATIC RAM
9330HBK
And here's what I could find about the chips for FF7:
Final Fantasy VII
CY6264-7051---------------128K x 8 Static RAM
9630 312158
Chip with no #------------?????
MX E013345----------------16M-BIT [2Mx8/1Mx16] CMOS SINGLE VOLTAGE 3V ONLY FLASH MEMORY
29LV160BTC-90
2E7700CC
So I wanted to know, if what I found was correct. And which chips would I need to find to make my own copy of FF7. The only flash memory chip I could find was for Naruto, but I don't know which chips I would need to find for the others.
