Yes and no. The only real difference between G and C major is that G has F# and C has F instead. That's a one note difference as far as tonal content goes. Anyway, since they're both major keys they will both have the same intervals, just with different starting points. Since you have chosen to lower it rather than raise it I guess it would be as simple as finding the note data and subtracting 5 from each note. It's a matter of simple mathematics. :)
I knew that C major is all naturals and G major has an F-sharp. What I really meant was the difference in the sequence of notes G major would use in that score relative to what C major would use.

I was hoping to point you in the right direction in case no one else showed up.  I suppose a link to and might have been slightly more apropos.
That is pretty helpful, though it would be nice to know what address(es) the notes to the Game Over score are located.

Yeah but there's only like a one or two note diff right? :)
I'd imagine it's actually a whole bunch of notes difference. We're talking about a different key here!

Gaming Discussion / Re: Is there a need for new game consoles?
« on: October 27, 2015, 08:26:16 pm »
So I was reading the SMM thread and someone mentioned the new Nintendo console in the works. This reminded me of a question that has been burning in my mind for a year or two. I thought about bringing this up in the other thread but I'm tired of derailing discussions with something that often is only semi-related. So, here we go...

Is there any need for new game consoles?

Can't they already do enough? What else do they need to be able to do that the current consoles on the market can't? I don't necessarily see the need beyond the marketing necessity of having something "big" to hype every once in a while to create a buzz around your brand name.

I personally don't think there's a need for new consoles. I think the newer consoles tend to focus more on graphics and special effects than on gameplay.

In fact, I wish they'd bring back classic ones like the NES back into production. They could also expand the capabilities of the NES and other classic consoles (i.e. maximum amount of memory per cartridge, save features).

P.S. Off the record, what color is "G Major" to you?  ;)
I don't know, but I'll tell you this: it's less fitting than C major in Super Mario Bros. 3. In fact, all of the main scores in SMB3 are in C major!

Is it a Perfect Fourth incrementation, or a Perfect Fifth decrementation you desire?
The latter.

That's all very helpful info, but I take it you don't know how to edit the music engine, do you?

For fun, I would like to transpose the Game Over music in Super Mario Bros. 3.

I know that NES game music is stored in NSF files, and I have just now downloaded the one for that game. I also downloaded GNSF, which is what I chose to play NSF files, and made a copy of the NSF file. When playing the file I discovered that the Game Over music is at track #31.

Now, I'm wondering: Is there some sort of technique I could use to locate the bytes where the Game Over music is stored, and a way to edit the bytes so that they play the same sequence of notes, but in a different key? Of all the music in the game, I only want to change the Game Over music.

I think the music is in the key of G major, but I want to change it to C major. What is the easiest way to do this?

Are you a native English speaker?
Yes, I am. I'm US-born and raised.

@Chpexo - Thanks. I think I'm starting to understand more now. I'll keep plugging along and I'll ask more question(s) here if I need to.

The first 10 bytes are the mapper. Basically it tells you what the circuit board for the game looks like because it is difficult to emulate the game otherwise. This can include specifications like sound chips (rare) and other stuff. If you'd like to read way more than you ever needed to know about mappers, click here.
OK. For instance, where would you find the first 10 bytes (or, the mapper) in Castlevania?
As for looking up text on the title screen, use FCEUX's PPU viewer to view the value of characters.
I'll try that. Thanks!
I can go into this in greater depth if you want.
Yes, please do that. I'd love to hear an elaboration.

Newcomer's Board / Hex Lesson Issues
« on: October 25, 2015, 12:20:29 pm »
Before I registered with this site, I took a look at the Getting Started section, and started off with hexadecimals. I was able to figure out how to comprehend the basics of binary and hexadecimal numbers by reading the first document, which is titled "Hexadecimal (The Basics of Bases)". However, for the second document, titled "Hex Lesson", I find an explanation that is either flawed, or is explained in a way that's hard to get.

  • The author mentions the first 10 bytes, but I'm thinking to myself: what are these first 10 bytes? Are they the first 10 in the whole page of bytes? Very confusing.
  • He asks readers to change every 8 bytes or so except the first 10. I tried finding bytes that were not in the "first 10", but the last time I tried that, I could no longer open the ROM. So I assume that I must have changed one or more of the real first 10.
  • He says he "took Castlevania‚Äôs title sceen and looked up words like push start now in a hex editor". I know what game he's talking about, but what does he mean by taking the title screen, and how would one look up text in a hex editor? (For the record, I am currently using Hex Workshop (32 bit).)

After experiencing these issues, I kind of gave up, at least temporarily. I'm sorry, but this "Hex Lesson" left me in a state of confusion. As I see it, the lesson is nowhere near perfect.

I'm just offering constructive criticism. And others may not find as much difficulty understanding the author, but please do note that I am more of a visual learner than anything else.

Is there a video (as in a YouTube video) or sequence of images out there that could help me better understand the science of ROM hacking with hexadecimals? If not, is it possible that the Hex Lesson could be amended to suit a more comprehensible and visual learning experience?

OK! Thank you very much for your help. I'm all set here. :)

Newcomer's Board / SMB3 Question
« on: October 24, 2015, 08:18:49 am »
I want to change the copyright date on the title screen of Super Mario Bros. 3 to fit its North American release date of 1990. I already know what the Japanese release date of 1988 is, as is reflected by what is currently on the title screen of the ROM.

I've tried every trick in the book I could think of, in this case using every utility available for SMB3, including the title screen editor. I know it has to be possible to edit, as I remember seeing the title screen date changed from 1988 to 2003 or 2004 or something like that for someone else's ROM hack.

Would the best way to edit the date be through one of those utilities found on this site, or would it be through a hex edit? If it's the latter, which I'm currently suspecting, please let me know what bytes need to be changed and the address they are located at.

Hi! As you may have deduced from my username, I am a fan of classic video games, video game styles, and video game consoles. About a week ago or so, my curiosity about wanting to edit/alter ROMs reached its peak, so I started looking into it, and so I stumbled upon this site.

I would like to use this site for help with stuff like editing/expanding sprites, text, levels, and music in ROMs.

Well, that's about it for this introduction. I'm looking forward in getting down to business with ROM hacking.
