Famicom Disk System games - bad dumps?

I'm not sure where to ask this so I hope it's okay here. Can somebody who is familiar with the Famicom Disk System games answer this question - I see the current No-intro set for the FDS has almost 100 games that are marked bad. From everything I have been told, No-Intro sets only contain good dumps, no bad ones. Yet that doesn't seem to be the case at all, at least not for the FDS. Some of those games aren't marked as bad in the Tosec set for FDS.

 

Is the Hyperspin XML for the FDS based on No-Intro? Because my FDS set checks out 100% with the latest Hyperlist DAT, yet if it's based on No-Intro, wouldn't that mean many of them were marked as bad? Most of the games seem to run for me in emulators but several give me a "disk error". Are there issues with bad dumps in the FDS set/XML?

I could really use some advice here because I'm trying to make sense of my fds rom set. As I mentioned, about a third of the No-Intro fds roms are marked as bad. Most of those aren't marked as bad in the Tosec set. If the Hyperspin XML for the fds is CRC-checking based on the No-Intro set, then a third of those fds roms were orignally marked bad in the No-Intro set. So I'd like to know if it would be wise to forget about CRC checking for the FDS and replace the roms I have with Tosec copies that are not marked as bad? Somebody here must be familiar with the fds roms. Do I need to be concerned? It worries me that so many of the No-Intro roms are marked as bad and I can't find out of the official Hyperspin XML is based off of that set.

 

Does anyone have any information on the fds xml or which rom set the CRC is verifying to?

CRC doesn't really matter if you just want to play the game. You can use the Tosec set if it makes you feel any better :) I personally have the no-intro set and didn't really encounter any problems with roms marked as bad. You can fuzzy match the tosec set with Don's hypertools for easy renaming.

The only time where CRC does matter is if you want to apply a translation patch to the game where it states that it requires that specific rom.

Thanks for the reply. I was checking this thread where they discus the XMl:

http://www.hyperspin-fe.com/forums/topic/25149-official-nintendo-famicom-disk-system-xml-database-thread/


and there is some mention of bad No-Intro roms on page 1 but I don't know if the latest XML has taken those bad roms into account. I have the latest  [2016-09-06] raw No-Intro set and there are quite a few bad ones - almost 100. I am actually using Don's hypertools which is very helpful. I liked the idea of everything being CRC matched for peace of mind but in this case, the large amount of "bad" roms in the No-Intro set makes me worry. I checked and most games load for me and seem playable, but if they are bad dumps then I worry that the games may have issues at some point in the game. A handful have given me disk load errors and won't even go to the main screen so some definitely seem to be a problem. So I'd feel better knowing my set wasn't based on bad dumps. I thought No-Intro was known as having only good roms, but that doesn't seem to be the case for fds.

 

What is the current state of the fds XML? If I have a set of games that match CRC 100%, what does that tell me about this set? If it matches, does that mean I have a bunch of games marked as bad?

The thing is - If I try to rebuild a set straight from my latest Tosec set, using the latest XML and Don's Hypertools, I only get 133/246 matched - and that's using Fuzzy and CRC combined. If I rebuild using only my No-intro set, I end up with 240/246. So the XML clearly is based on No-Intro.

As one example:

No-Intro: Galaxian (Japan) (Disk Writer) [ b].fds

Tosec: Galaxian (1990)(Namco Ltd.).fds

 Why favor the No-Intro when it's marked bad when the Tosec isn't marked bad? There are dozens of examples like this in fds.

 

If I pull out all the games marked bad from both my full Tosec and No-Intro sets and rebuild with the latest XMl and Don's Hypertools, I end up with only 214/246. So the rest I would still need to fill in with the games marked as bad I guess?

Well I think I got my answer in the XML thread. I wasn't aware that No-Intro is more thorough with their naming of bad roms than Tosec. So I guess from what I've been told that if No-Intro marks it bad, but Tosec or other collections don't, then that game is likely bad regardless of which set it comes from, since No-into is more thorough with their naming and always uses the best available rom.
