Loading ROMs with a header

Cecil · Post by **Cecil** » Tue Sep 28, 2004 6:58 pm

First off, I'm using the 9/20 WIP, but this started happening ever since Nach added support for the special NSRT headers in zsnes. With some ROMs, if it has the header that NSRT identifies as "Exists (type?)", it won't load, and the ROM info that zsnes shows on the bottom of the screen is garbled. It's even worse with Dual Orb 2. I had just downloaded and patched the game this morning, and forgot to remove the header afterwards, and zsnes crashed when I tried to load it.

Edit: By the way Nightcrawler, you and your team did a good job on the patch. Good luck on your projects!

I think you can fix it with -addhead instead of -addnsrt

I'm not talking about the special NSRT header that's used for Games with special controllers such as Mario Paint. NSRT indentifies that header as "NSRT". I'm talking about the header that NSRT adds to the ROM when you do use -addhead. The one that it identifies as "Exists (type?)" when you scan the ROM in NSRT. I was just saying in the first post that it started happening when NACH added support for the special NSRT headers.

Well, I know NSRT 3.3 has 3 header modes:

-addhead: adds a normal header

-addnsrt: adds the NSRT header

-addspec: adds the NSRT header for special control games

Also, you can try to run your game without a header.

That's what I do. I was just making the glitch known. With Dual Orb 2, I just forgot to remove the header after patching the ROM since the patch requires a ROM with a header.

I'll look into the problem sounds a bit weird though, we'll see.

Edit:
Test example:

Code: Select all

Sorry, I should've mentioned it doesn't happen with all ROMs, though I don't know why. Maybe try some other ROMs? I'll get back to you in a bit.

Maybe you should send Nach a problem ROM.

Cecil · Post by **Cecil** » Wed Sep 29, 2004 6:19 am

Nevermind, now it's not doing it for some reason, and I tried every ROM I have.

And there all NSRT verified good dumps, except the ones I hard-patched, of course, so I don't know what's going on. I do know that this morning, after getting Dual Orb 2 and hard- patching it, it caused zsnes to crash until I removed the header. Then it worked fine. Oh, well, it's 10pm right now, so I guess I'll play a game for a bit and then go to bed and try to figure it out tomorrow.

What program did you use to hard patch the game? There a few out there that can mangle the ROM because they have some bugs.

Cecil · Post by **Cecil** » Wed Sep 29, 2004 4:16 pm

Nevermind on Dual Orb 2. I was using SmartIPS to patch it. I tried using SnesTool and it worked fine. But I know I had problems in the past with loading ROMs with this kind of header and It was happening with original, NSRT verified good dumps of ROMS. Maybe it got fixed without anyone realizing it?

Oh, well, the subject is starting to make my head hurt, so if it happens again, I'll let you know then.

Ok.. that's good to hear.

For future reference I usually recommend SNESTool(DOS)or LunarIPS(Windows) for IPS patching.
