Probably goes in this order:
42 = P1 ROM
43 = V1 ROM
44 = V2 ROM
51 = C1 ROM
52 = C2 ROM
32 (53?) = C3 ROM
41 = C4 ROM
AM27C010 = S1 ROM
29212 (?) = M1 ROM
That's if we presume this board is copying the physical layout of official SNK boards, which I think it is. If not, the C ROMs might have this arrangement (going by the solder mask):
51 U1 = C1 ROM
53 U2 = C2 ROM
32 (53?) U3 = C3 ROM
41 U4 = C4 ROM
42 = P1 ROM
43 = V1 ROM
44 = V2 ROM
51 = C1 ROM
52 = C2 ROM
32 (53?) = C3 ROM
41 = C4 ROM
AM27C010 = S1 ROM
29212 (?) = M1 ROM

I knowCan eeproms be readed to see wich roms the contain?
The other ones are probably mask roms or maybe OTP EPROMs (one time programmable, no window)
They can usually all be read to see what they contain, if you are able to determine a compatible chip to tell your programmer to configure for. For example the neo geo BIOS can be burned to a 27c1024 eprom, so the stock mask rom can be read using the same pinout.

I know
You can use the unibios to test the cart. If it comes OK, that means the program chip (P1) is the same as the original carts. To test the rest you have to desolder and read them with an EPROM programmer.
