This file with CRC32 84F95868 marked as [f1] in GoodSNES.

The verified one has CRC32 1D123BE6

Are there any mistakes here?

There have been cases where Goodtools mislabeled the games. But there have also been cases of No-Intro using incorrect files, yes. The best thing to do would be to redump the game in this case.

In the case of some games, they may be too rare/expensive to redump. Prototypes, for example. Maybe someone can have a look at the bytes and tell us something about it?

There isn't much info on the net at the moment for the verified CRC32. If that's a recent change/dump, No-Intro probably has it wrong. No-Intro used Goodtools as a launching point many years ago, and so inherited some of their bad dumps that may still be around now.

Thanks!

I hope somebody who knows the point more deeply will join this discussion ))

This rom is indeed bad (hacked), and the one from MAME with CRC=1d123be6 is the proper dump. Ikari_01 analyzed both roms and found the current one in the DAT to be hacked: "so the no-intro / goodROM apparently has the rom type flag set to slowrom instead of fastrom (which the game uses) and an SRAM size check patched out. It writes a test word to SRAM and then reads it back from the same address instead of address+0x800 to check correct mirroring."

Correct file added to Datomatic. Big thanks to everyone involved in righting this error. :3
