Just match the part number on the chip inside the case. For instance, the Pokemon Yellow cart linked above uses a 29LV160 part. You can order some of those chips and what ever other hardware you may need (like a compatible socket adapter for flashing or for fixing to the board) and it should work just fine.
If you have issues finding the part number just post a high-resolution image on this board.
Thank you

thats a shame

Just based on the cart edge, the chips on the right are the PGM roms
The chips on the left all end with '64' part #s, so willing to bet they are 8Ks.
Just a guess without google'n

Somehow I entirely missed the images and request.
King of Fighters R-2: The TC55328J is a 32KiByte SRAM. The LC3664BML is a 64Kibit SRAM. The entire rest (ROM, mapper, &c) must be under the epoxy blob. If you have (or can make) a veterinarian or dentist friend, you can get an xray taken and figure out where in the blob is what, and then you could count bond wires to determine the size. The 32KiB SRAM is for CHR, so they've got to support banking it somehow.
Samurai Spirits Showdown 2: Only two visible part numbers here. The CXK5864CM is another 64Kibit SRAM. The other IC doesn't have an obvious part number. On the back, the part number "481F16M" strongly implies 16Mibit, but it's odd because it has 44 pins—12 more than it needs. Googling for 481F16M does find someone else mentioning that part number of a Nanjing FF7 copy. There are four total epoxy blobs, and while the two under the "481F16M" sticker are almost certainly ROMs, I have no idea why there are two for the other one.
Naruto: MB8464 and GLT7256L08 once again specify the number of Kibits. The MT28F016S5 is 16Mibit. I even recognize that manufacturer logo: the MT is Micron(.com).
For all of these, the smaller SRAM appears to be 8KiB for battery-backed save memory. The larger SRAM is 32KiB and appears to be for CHR RAM. The other non-epoxy blob (when present) is the PRG.
