It tries to compare 0xaaaaaaaa to 0x00000000, so the indexes are not correct. Unfortunately I don't have much experience with writing formats for john and it goes slow.

You seem to have "partial hashes" with a size of 32 bits so they are not partial. You should not need res_hashes and cmp_exact should just return 1:
cmp_exact()
{
return 1;
}
...because cmp_one() actually made a full compare.
