OK, so I've been working on a project on Fire Emblem: Blazing Sword (FE7).

Here's the story:

Everything has been going smoothly so far. I was able to make patches before.

Now, while inserting graphics (I use unlz-gba) I have had problems with the images being too big. Before, I used to just chop off some pixels to make it fit, but that lowered the quality.

I then discovered how to use an expanded ROM. I then expanded the ROM from 16MB to 32MB. If the image was too big, I would just repoint it to somewhere else in the ROM.

Now, here is my problem. I can't make a patch (obvious from the topic title).

At first, I was using an unexpanded ROM (16MB). It said that I couldn't make a patch because I went beyond the 16MB. I thought that I should just expand the "unmodified" ROM to do it.

Well, that didn't work. It still said that I couldn't use any offset passed the 16MB mark (which is 0xFFFFFF in my ROM). It said that the IPS format isn't designed to go that far.

I used both Lunar IPS and WindHex32 to try and make the patch. Neither of them work. They even gave me the added bonus of corrupting my ROM and not allowing me to load it in VBA.

So my question is: Is there any way to make a patch with a 32MB ROM?

Without this, my project will have to go back to release v 0.1, and that's something that I don't want to do.

Thanks for your time.

You could use NINJA or a program like that to make a UPF, PPF, or other format that supports large files to make it. IPS is starting to become less useful...

You could take the first 16 MB of the file, make a patch with that, and then include the second 16 MB as a separate file, and tell people to apply the patch and then attach the extra data... it'd be somewhat tedious for the users, but it should work.

Thanks for the suggestions. I'll try both of those methods.

sirhax0r, would something like the IPS Patcher work with a UPF, PPF, etc? Or is there another tool that I (and everyone else who would want to play) would have to have?

Thanks for the input.

EDIT: Well, I'm having a problem with Ninja. It makes my ROM 2GB and doesn't make any changes at all. I am using PPF format.

EDIT2: I'm trying to use two patches, but I have no idea how to even create to separate ones. I know how to apply them, but how do I make them? (I'm using StealthPatch to apply them).

My suggestion would be to just use the PPF format and forget about making two separate patches. PPF can handle much larger file sizes than IPS, and you would only have to make one patch.

Actually, the two patches method works just fine.

I couldn't get the PPF format to work properly.

Thanks for the suggestions everyone.

Yeah, IPS can't modify anything past the first 16 bytes, and some hackishness is required to modify address 0x454F46 (ASCII "EOF").

I'd love to see a patch format that actually supports moving and repointing data, but I guess nobody's going to actually make one.

Actually, I was thinking about something like that not too long ago. However, it would basically eat CPU power unless you actually told it what had been moved. And, repointing? Yeah, can't you just overwrite the original pointers?

I mean like being able to insert data in whatever free spot is available and update the pointers, or move data without having a copy of it in the patch (e.g. for NES expansion), or support multiple versions whose pointers are in different places. Most of these features would probably be of more use for small hacks in which you'd create the patch by hand.

Suggestion: Don't make a patch. Send GBA files for download instead.

Despite the necro; in's "unethical" (*snicker*) to be sending ROMs, quite the big no-no for actual finished hacks. Patches are the preferred way to do it.

Without reading through the thread, shouldn't taking the original ROM and expanding it to 32MB, and then taking the new hacked version and splitting the two in half, be another way to get smaller patches out of the game? It'd be slightly more complex for some people, but then you'd have patches for two separate 16MB files, rather than one 32MB one :[

big emphasis on "preferred". if you have problems making patches you should just then send the gba file. why is it preferred to make ips files anyway? that just means extra wok for both sides... (what if it doesn't successfully patch? that's what i mean mostly by the extra work part...)

Go read up on the laws of your country. They quite clearly state that pirating is illegal.

We don't wanna get nuked by the FDA or whatsit.

So we don't send ROMS unless it's Sonic 1/2/3 for Genesis. Those things can get so many changes that an IPS patch would be nearly the whole ROM.

tl;dr: It's illegal.

We don't send ROMs. Period. I don't care what you say about IPS patching; as long as its in that form, it's good.

KP9000: Sonic 1 Megamix. Where just about everything's changed. An IPS patch would be just as illegal as the ROM in that case.

OY, ARE YOU A FUCKING DUMBASS OR WHAT

I clearly said... hell TWO people have said that that method is completely unacceptable and illegal.

And you misspelled illegal.

stop yelling at me i get the point.

...If you can't then send gba. and ok already i get the point sending gba file is illegal. but he cant make a patch. if he could then he should. if he can't then sending the gba file would make everything much easier. i'm saying you don't have to send gba file instead of ips if you cant make an ips. geez i need to elaborate moar. i'm saying it would make everything easier if he sent the gba file if he cant make an ips. k? case closed end of story.
