I never did get around to doing it.
But I WILL tonight - if I don't succed, I still have a stash of codes that I think can't be found on the 'net.

EDIT: New fix that works with more games.
For Animaniacs, Castlevania, Probotector, Sparkster, Turtles 2, Zombies:
·Look for the first "00A1 0001" and replace it with "00A1 4E71"
·Fix checksum.

Hello ,
I try to unlock Probotector, but I still got the freezing Konami logo...
I'm not sure if I did correctly the replacing with 00A1 4E71.
I used a hex editor and line 000003B0 I found 00 A1 00 01 , then I replaced it with 00 A1 4E 71
Is that correct ?
Thanks for any help

Yes, that is correct and I've just tried it and it does work properly... Make sure that you're using the correct altered ROM that you're saving.

Thanks Ice Knight ,
I tried again , and still freezing konami logo on Gens32 emulator. (I fixed the checksum)
Also tried on real hardware (repro cart) , got black screen.
I have no idea what I did wrong....
Possible to upload the modified rom somewhere Ice Knight ?

Okay, I guess I shouldn't have used Kega Fusion for testing... Real hardware gives me a red screen even after fixing the checksum.
I wish I knew how to fix it, sorry.

Oh wait wait wait, didn't Konami games need a different kind of checksum than usual? Something like the checksum of just half of the ROM or something like that?
That might be the problem.
