SNES PAL Spider-Man badly dumped: PAL games need redumped

This is "Spider-Man - Venom - Maximum Carnage (Europe)" from the SNES section. Byuu is redumping PAL cartridges now and found this very quickly. This is clear evidence that other PAL (and maybe some in the Japanese set too) could potentially have been badly dumped and hacked to correct the checksums afterward. Unfortunately, this means we should treat every ROM from the Goodsets as potentially being bad unless a reliable dumper has verified otherwise. :(

I'll fix this example in a moment.

EDIT: Fixed on DOM. I hope there aren't a lot more like this. Regardless, it's now clear that ROMs from the Goodtools sets can't be assumed to be good even if they're listed as verified. This Spider-Man game was listed as verified in GoodSNES, for example.

If anybody has carts they would be willing to send me to verify I could lend a hand. Of course I would return them as well. I only have a few SFC unfortunately but will check them in the DB to see if they need verification.

This is nothing new, GoodTools have always been a pile of crap. But don't fret, this will be an exception. Most of the PAL library has been redumped by trusted dumpers. In fact I think I (re)dumped 50-60% of it on my own.

2 questions:

- Did anyone report this to cowering yet? IIRC he always idles on IRC somewhere

- Are all the [!] goodtools dumps currently marked as verified in the no-intro verifications csv?
