Help applying IPS patch

nachch · Post by **nachch** » Sun Sep 09, 2007 4:16 am

Hi,

I'm trying to apply the IPS translation patch (by Gaijin) to a "Do-Re-Mi Fantasy - Milon no DokiDoki Daibouken (J)" rom, unsuccessfully.
(The rom seems good according to nsrt).

All the following methods failed:
1. Having ZSNES autopatch the rom. The patch file was found (I got the "IPS" indicator in the rom loading status), but didn't seem to have any effect.
2. Hard-patching, still no effect.
3. Adding a header, repeating the above --- still no effect.

Has anyone here successfully used this patch before? what am I missing?

(I *think* I know what I'm doing, but this still refuses to work...)

I'd still suggest you post the NSRT output anyways, just in case.

Here is nsrt's output:

To be on the safe side... run the rom without the patch. If it doesn't work it's probably an emu bug.
You can also try using ipsedit to remove the header offset from the patch.

I think I've been misunderstood:
The ROM works fine; however when the game runs it is untranslated...

I found a hard-patched version of the ROM online, and that one does work as expected (i.e. English dialog so I know this translation patch should be good).

My problem isn't really a ZSNES problem at all, more of a general question about what can go wrong when trying to patch a ROM. (As you can see in my original post, I tried hard-patching --- but it failed in the same way the soft-patching does: the game plays fine, but the patch seems to have had no effect).

Kinda baffled here, anyone has any idea?
Thanks.

Beats me... you probably are not hardpatching in the correct order (header addition/removal first, then apply IPS patch) or your IPS patch is placed in the wrong directory and/or incorrectly named.

Well, there's just one rom file and one ips file, so not much to get wrong there.
As for the matter of headers, I tried both without a header (the rom as is) or after adding a header.

Nothing has worked so far.
I'm sure I'm missing something stupid... but I have no idea what...

Thanks.

What are you using to hard patch? Use LunarIPS for your own good.

nachch · Post by **nachch** » Mon Sep 10, 2007 1:04 am

I'm using LunarIPS...

Are you sure it is not working?

According to the readme:

What's not done
---------------
-Any text that uses non-font graphics (They're compressed)

nachch · Post by **nachch** » Mon Sep 10, 2007 1:17 am

Yes, I'm sure...
Title text is graphic and is not translated, I know.

But the dialog of the intro should be translated, but it's always Japanese for me, no matter what I try.

I would appreciate it if you could try the patch yourself...

Thanks!

I'm not sure what's going on here.. it's not doing anything for some reason...

nachch · Post by **nachch** » Mon Sep 10, 2007 7:54 am

Yeah, that's my problem

The patch was made with an interleaved ROM.

nachch · Post by **nachch** » Mon Sep 10, 2007 12:45 pm

Ah, that would explain it, I guess (there's no mention in the attached readme... how can you tell?).

Anyway, is there a tool for:
1. Interleaving the rom? (nsrt can only deinterleave, iirc)
2. Fixing the ips so it can apply to the deinterleaved rom?

Thanks!

I really have to release my new version of IPS edit which can deinterleave patches...

If someone can collect for me a few interleaved patches, I'll turn up my time table for that project.

Deathlike2 · Post by **Deathlike2** » Mon Sep 10, 2007 1:20 pm

AFAIK, Dejap's TOP released such a patch for both interleaved and deinterleaved versions of the game.

nachch · Post by **nachch** » Mon Sep 10, 2007 1:42 pm

Well, there you have *one*

But seriously, I think all I need is a utility to interleave a rom.

Once I have that I guess I can just go:
1. Interleave ROM
2. Apply interleaved patch.
3. Deinterleave patched ROM.
4. Create new patch from the final product against the original ROM.

I've done some reading on SNES rom interleaving.

It seems I've been talking more-or-less out my ass --- there is no way to "re-interleave" a rom, since there are many types of interleaving schemes and I have no way to tell the exact one that was used on this particular rom...

Try all of them?

I advise checking out the brand new, better patch.

Tada !

Hey, thanks!
(could've sworn I've searched romhacking for a newer patch... oh well).
