Nestopia 1.39

remember that if it's coded with a (!) or [!] (it's been awhile since I downloaded any ROMs) it's a good dump.

Even if that is the case, Nestopia gets the ROM info from its internal database (assuming that the database is enabled, which it is by default). Since I.S.T.'s dump is not working right, I assume it's not in the database. Hence, a bad dump.

Code: Select all

        <cartridge system="NES-NTSC" dump="ok" crc="1335CB05" sha1="8A49FE60B6A151C055A63639894CD366935A7EE9">
            <board type="NES-TKROM" mapper="4">
                <prg size="256k" />
                <chr size="128k" />
                <wram size="8k" battery="1" />
                <chip type="MMC3B" />
            </board>
        </cartridge>

Aha, there it is. Must be a bad dump, then.

Hmm, the text/XML file generated by Nestopia is strange.. since it doesn't quite generate perfect text...

Jesus christ.

All of these bad dumps were labeled U or U !... Frigging annoying.

GoodNES! Where less than half the games indexed are good dumps!

Probably all of those alpha, beta, and overdumps.

My account on the "official" Nestopia forums got corrupted a while back when Mr. Bannister was doing some kind of maintenance, so I hope nobody minds me reporting this here:

Regarding the NTSC filter, in games such as Battletoads where the composite-video artifacts are supposed to cycle through all three possible phases, they instead appear to be locked to one phase in Nestopia 1.38. No adjustment of the filter parameters or any other video setting has an effect on this. I know that 1.37 had the right behavior, and I'm guessing that this issue has something to do with "Some video filtering work offloaded to the GPU."

And now, I can't save anymore. Did the same deal, tried it from a billion different sites, all labeled U or U !.

Fucking NES emulation. No wonder I don't fuck with it very often...

Thats if Nach is around. I haven't seen him on IRC for ages....

After quite a long time, I figured out why it stopped working, and what was wrong in the first place.

nestopia is keeping the mapper information for each game the same even if you use a slightly different file. When I loaded a save state I had made, it changed the mapper info to the old info, thus preventing the save.

>.< So, basically a combination of a header or two mislabeled and my own idiocy set off this ridiculous search.

Thanks, I've just finished coding up the UPS feature now. Extra neat since I can now take advantage of CRC validation when loading/saving Famicom Disk System image patches!

byuu wrote:The one issue I see is with the multitude of NES ROM formats abound: the patches would need to specifically target each format, iNES v1/2 (make a patch that includes the header), UNIF (direct file patch) and XML schema (one patch for both the XML file and the binary file). One patch can't apply to all ROM types, sadly. I couldn't keep the patch format simple and account for all possible console image formats at the same time

Yeah, it's a dilemma. What I do right now for XML and UNIF patching is to assume iNES patches, adjust its offsets and simply apply it to the PRG+CHR data read into memory. Not bullet proof since the header could have been modified as well but still better than nothing.

Hmm, did the licence change at some point? Here's what it says in the sources I have:

I have a vague memory reading something on the official site about the author wanting to rebase it to GPL. Can't recheck since the link seems to be dead now unfortunately.

Not sure I understand. Could you elaborate?

Shit, you're completely right. Bug fixed. As for your account. Have you talked to Richard about it? If it's completely hosed couldn't you just create a new one?

When his website was still up, I believe it said something along the lines of "ZSNES has the latest version of the source".

It could be Metapad at fault for sucking badly, but I'll have to try Notepad+ (and in the worst case, Textpad) so these issues go away...

nes_ntsc also comes with a few test ROMs to verify all aspects of the artifact changes between frames in various cases.

For those that might be curious, there was a third factor.

The game only allows you to save on the world map. >.> Which basically puts 2 in the stupidity column, and 1 in the header misnamed on some of the roms column. >.>

Textpad is way better than most text editors out there.

Of course, Gvim is also very cool.

That's because the database now fixes incorrect iNES file headers for that dump.

Clements · Post by **Clements** » Tue May 06, 2008 6:37 pm

It's always a good idea to check that the headers of your NES images are correct. That is probably the source of most peoples' problems, rather than a genuine emulation bug.

How about getting the super eagle filter in Nestopia? I really like this filter in zsnes, it's the best compromise IMO.

Xtreme2damax · Post by **Xtreme2damax** » Tue Jun 10, 2008 4:36 am

I've been using this release for a while and is nice. Nestopia is one of the best NES emulators with a lot of features, nice to preserve my collection of NES games and be able to play them since I have a non-working system.
