Hi,
you had already mentioned a similar subject some time ago about the tag [b checksum error]. The reason is simple, I process the games 1 by 1 and not only to change a tag or two. I examine all the disks related to the game. For the "RVF Honda" game alone, I have analyzed 88 disks (for the next release).
the [no intro] tag is going to disappear but this requires examining the different versions to determine who did what compared to the original.
For information about this last publication, I have reviewed 208 games and that's not bad...
