I finished redumping 55 discs using minesweeper (that were originally dumped with IsoBuster).  There were some errors so it was worth it.  I dumped these twice using minesweeper, just to be sure.  Here are the corrections:

There's one more game that needs a correction, I'll post about it separately.

FIXED

thanks bsbt, I would have liked to ask you for this check for a long time.

Please can you check also N3: Ninety-Nine Nights (http://redump.org/disc/12506/) because it is bad at 99% (both scene and other individual releases match with another checksum, obviously after fixing it).

My patch requests thread
--------------------------------

I don't own the N3 disc, and I think the rental place got rid of it when N3 II came out.  Still, I'll try to hunt it down.
