Hello everybody
I want to clean my cps2 Vampire Hunter Board. Just changed the battery and it seems to be some graphics flickering in some moments (specific stages) of the game (barely visible). I wanted to clean all the Eprom on the board to be sure it's not a contact issue. Can I simply get them out, one by one and try a dry clean ? or some Eproms needs to stay in the board because of the encryption key ?
It's maybe stupid question but I don't want to kill the game :-)

Thanks in advance

You can remove them all, the encryption is within a different portion of the board.

If it is the characters at certain animation frames it is normal.

If you do want to clean them just take them out and clean with contact cleaner on the legs + q-tips. Just be careful not to short anything near the battery, especially the capacitor right by it. If you do the encryption keys will be gone.

not that big of a deal nowadays with infinikey and key restoring but a minor inconvenience.
