Some issues with BS SNES roms...

Hey guys, I was wondering what my problem is with these. Basically, NSRT sees all of my BS roms as good. They are headerless, non-interleaved, and have good checksums. But the latest no-intro SNES dat with Romcenter 2.71 results in only 1/4 of them being recognized. So am I doing something wrong or is something else to blame?

I suppose this may not account for all or even any of your problems, but are your ROMs in some sort of archive format like .ZIP? If my memory serves me correctly, Romcenter isn't always able to decompress all .ZIP archives. So try extracting your ROMs and rescanning.

I do not know the details but the No-Intro BS roms were modified at some point compared to NSRT verions. Your best chance would be to find and download them somewhere.

The roms are not compressed and all have .sfc extensions. Some are recognized by no intro, most are not. Nach didn't elaborate too much on it when I asked him, other than saying that NSRT had better detection and handling of these files. Whatever the reasons are, it would be nice to know if someone is doing something wrong, NSRT, No Intro, or RomCenter. It will help both projects and I plan on contributing to both in the future.

What was the system where we encrypted the US ROMs to make them more like the original carts i.e. to stop them working on Japanese consoles?

I thought it had something to do with the date on which the game was downloaded from the Satellaview system. IIRC Nach uses the original dates, while NGEfreak modified the dates (or the other way around). Please correct me if I'm wrong.

If this is true, then I'm curious about how exactly the dates were modified.

The date of the BS roms are currently padded with FFFF and I may be change them to when their first broadcast date. but first I need to find a accurate broadcast list.
So it seems the broadcast date is stored in the ROMs. Nach kept them their original date, while NGEfreak padded them with FFFF.

Thanks for the look-up.

I'm getting too old to remember all these changes/clean-ups. :evil:

According to Nach:
An FFFF date is invalid. I also believe that any BS dump with a valid date is a valid dump. Hence NSRT/uCON64/ZSNES/Snes9x have all followed a single standard to recognize BS dumps with multiple valid dates as the same one.
So if he's right, someone might want to tell NGEFreak to change them back...

They won't be changed back.
If any BS dump with a valid date is a valid dump, we would need hundreds of clones for every BS dump. That's why we will use only the first broadcast date (instead of a random one) when we get an accurate broadcast list.

Alright, well I guess I'll have two sets then for no intro and nsrt. Would it be hard to pad the roms myself if I already have them. How would I go about doing this?

EDIT: nm, time to make my own dats. Too many inconsistencies here. No naming/inclusion doctrine, 3/4 of your beta games are relegated bad dumps in disguise, and including subtitles from title screens is rubbish.

I've padded the date to a consistence value because ClrMamePro can't handle BS roms like NSRT/uCON64/ZSNES/Snes9x. However I dedicated to use FF and not the answer to life, the universe and everything (42) which is used by NSRT/uCON64/ZSNES/Snes9x. ;)

The current hacked BS roms will eventually be removed. However not only the first broadcast version will be added, every possible version will be added! Yes, this means some games may be added like 30, 60 or more times with the only difference being 2 bytes (sometimes more if they created a newer version for example). But I guess we will never see them all included anyway since we will probably never see new BS dumps. :cry:

Which beta versions are bad and why do you think they are bad?

I think subtitles are important information and I don't see any reason to not include them. The title screen is by far the MOST important title for ROM images! Anyways, since the title from the box or the title from the media label are also important information and many people prefer to use them, a primary goal of the so called "No-Intro World Domination Project" is to fix the ever ongoing naming debates once and for all.

Alright, enough on the bs-x issue, I understand now.

I am scrapping all beta and sample games that have final, commercially released versions. There is too much uncertainty surrounding the majority of these roms. Take, for instance, Pop 'n Twinbee (sample). The game does not work on anything. Since it's obviously a bad dump, how do we know if it's a bad dump of a sample cart or a bad dump of the official cart? There is so much crap like this that got carried over from GoodTools, it's not even funny. All betas are anyway is a development stage, of which there were hundreds of unfinished builds, so people who keep indexing them are just silly. Okay, so someone got a hold of a beta build before release? So what? It's one of many that we can never find or verify, and the differences are usually just bugs and other novelties. It's a total diversion and a bother from what's really important.

Games that only exist in beta form are bit different, as well as unlicensed carts/add-ons/copiers. For these I will have a separate dat called "scraps".
I think subtitles are important information and I don't see any reason to not include them. The title screen is by far the MOST important title for ROM images!

I'll give you this, as I debated myself what would be the best method. I'm going to come up with some logic that goes for the most descriptive of the two, which is pretty much what you're doing already. Neither boxes nor title screens are wholly dependable.

Don't think so, since NGEfreak doesn't give a sh#t about ROM collecting and essentially it's the right thing to do. If a game is dumped with 10 different broadcast dates, there will be 10 different versions of the ROM.
Because I am mainly a collector, I think the padding with FFFF is fine, since it only gives me one version per ROM.
I also don't think any more BS ROMs will be dumped. Isn't it true that only BS games that someone has on his current BS card can be dumped?
