Just tried this on my CopyNES CNRAM cart, and I get different results every time I reset. These are the different results I've managed to get so far:
112 12 / 124 24 / 134 34 / 156 56 / 1FF FF / 3D5 D5 / 7D1 D1 / FAIL
124 12 / 154 54 / 3D1 D1 / 3D2 D2 / 3D3 D3 / 540 40 / 7D0 D0 / 4
124 12 / 178 78 / 1FF FF / 3D2 D2 / 3D3 D3 / 3D6 D6 / 5CD CD / FAIL
124 24 / 129 29 / 12E 2E / 15A 5A / 164 64 / 3D5 D5 / 7D0 D0 / C
151 51 / 164 64 / 3D1 D1 / 3D2 D2 / 3D3 D3 / 3D6 D6 / 566 66 / 56B 6B / 5
178 78 / 1FF FF / 3D1 D1 / 3D2 D2 / 3D3 D3 / 3D7 D7 / 5CD CD / FAIL
It should be noted that my test method does not work "properly" for any test ROM which expects to begin at exact poweron, because the CopyNES BIOS always takes control at startup and has to check whether it's in Play or Copy mode (which can also affect the contents of RAM).
Thanks. Your results looks more accurate.

looks like for everdrive this will be as:
100 FF/ 124 12/ 178 78 / 1FF FF /
300 D6 / 3D2 D2 / 3D2 D2 / 3D2 D3 / 3D6 D6 / 5CD CD / (what exist in rom)
here's two additional writes that ED produce.

12E 2E / 134 34 / 156 56 / 1FF FF /
356 D5 / 3D5 D5 /
700 D1 / 7D1 D1 /
and there's also very close. but for some reasons ed makes some extra strange writes.
