Hello,

>> ROM 65254 65334

or in Hex: $FEE6 and $FF36

Must be 121 138 and is the same as 251968-01.

So use 65509 (in hex $FFE5) instead of 65334 as the second test value:
ROM 65254 65509
251968-01 121 170
251968-02 121 202
251968-03 121 235

Now have a look at the 901229-roms:

all_901229 same_as_above 170
901229-02 16 170 (Japanese 1541 roms)
901229-06 236 170 (lastest revision roms)
