1, 3, 4, 5, 10, 11, 13<br>
* Not in your dump, dumped by me, but looks like bad dumps<br>
6: Beeprog refuses to verify this. Top3000 produces consistent reads, but with fixed bits. Probably bad.<br>
7: Beeprog dumps and verifies this, but it's all 0xFF<br>
14: Beeprog dumps and verifies this, but it's all 0x7F<br>
* In your dump that I could not dump<br>
12: Beeprog would not dump this. Top3000 did give consistent reads but they do not match yours, and I think my dump looks worse.<br>

update 20250103:
From Angelo Sales: The sound string is actually from US Championship V'Ball
From Buffi: I did spend some more time on this and ran the roms through two other programmers I have as well and unfortunately don't have a great result, but summary so far is:

  • Matching dumps

1, 3, 4, 5, 10, 11, 13

  • Not in your dump, dumped by me, but looks like bad dumps

6: Beeprog refuses to verify this. Top3000 produces consistent reads, but with fixed bits. Probably bad.
7: Beeprog dumps and verifies this, but it's all 0xFF
14: Beeprog dumps and verifies this, but it's all 0x7F

  • In your dump that I could not dump

12: Beeprog would not dump this. Top3000 did give consistent reads but they do not match yours, and I think my dump looks worse.
15: Neither programmer produced consistent reads for me
16: Neither programmer produced consistent reads for me

  • In neither of our dumps

Unmarked m27512zb: Could not read
8: Could not read
9: Beeprog could not read, Top3000 read it as all zeroes
