Sure thing, subscribe to my new channel, @aura-hacks, dedicated specifically to rom hacking to see more! Thanks for watching!

I can’t find your other channel

youtube.com/@aura-hacks

@@aura-audio there’s nothing there on the channel but a playlist.

There will be videos in the future. This is a channel I run amidst the 1000’s of other things I have going on in life. I try to create content I enjoy while I can, and I appreciate you taking time out of your busy life to suggest more video ideas 🙏🏻

Hey thanks for watching. For inquiries you can email evan@auraaudio.io

@@aura-audioI sent you a message on instagram or do you prefer email contact?

My tier list for ROM hacks: CrystalTile2 > yychr > TM

They're all great, but I started using CT2 more in my recent vids

Have you watched my recent video where I show how to play audio on the Gameboy Advance? The sample buffers are basically like that.

Good question, it should be the same for the most part. You can download Audacity for Windows and then use MinGW or git bash for the command line

@@aura-audio yeah, i alr had audacity, but the problem was i don't have stdio.h, stdlib.h, and string.h . do you know what that could mean?

Oh have you tried <iostream>? Those are io libraries for bit streaming and some file stuff or the print files. I can't remember, but I think <stdio> is the windows one and <iostream> is unix or vice versa.

@@aura-audio I've not tried it yet, but I will now that you recommend me to do so. Thanks!

Definitely, that sounds like a cool idea! Thanks for watching and for your suggestion!

Thank you! Unfortunately no, I think all the code should be in the videos though.

Hi thanks for your question! If I remember correctly, you can use a sampler node which acts as an audio player. You can register an asset (audio file) with that sampler node. Then when you're ready to play you call play or start.

i wanted to rom hack kirby and the amazing mirror

You can download Java on Windows too! Search "how to install Java on Windows" and it should direct you to the Oracle website to install it

thank you :)

Anytime!

Definitely, if you do end up using it and it works, please help share the word of this video!

​@@aura-audio will do

Thank you for watching! I didn't think many people would enjoy these episodes, but now you've motivated me to make more 🙌🏻!

@@aura-audio Please I am using this tutorial for an app I am doing.

Sounds like a dope idea!

Thank you for watching! Hmm, is this SwiftUI? Yeah there might be a behavior specific to ScrollView you would need to override to avoid that.

Glad I could help 🙂!! Thank you for watching 🙏🏻!

That's awesome! Thanks for watching!

Hey there, thank you for watching! Yes, you're absolutely spot on! It's possible the sprites in the game you're looking at are compressed, and in that case TM wouldn't be the best tool for the job. As you get further along in the playlist, you'll see my later videos where I use tools like CrystalTile2 which can actually search the ROM for compressed graphics. Keep up the good work, and let me know how it goes 🙌!

Oh, i’ll try that instead! I’ll let you know if I manage to successfully view the sprites

Well…I tried…but I just can’t seem to get it. I’m not wanting to edit or hack my ROM, just simply rip the sprites, so do I still need to fiddle with palettes and stuff? Or are there relatively easy-ish steps to decompress and have the graphics be then puzzled together after i’ve opened up my ROM file and changed the tile format to GBA 4bpp?

Play around with this one and let me know how it goes: www.romhacking.net/utilities/973/. If it's successful, maybe I can introduce it in a future video.

Well, I think i’ve got it working now! I clicked on a specific graphic in a long list that it instantly provided for me (after I changed the filtering to “minimal”), shifted everything over, and it revealed a picture! The only issue I have left is that everything is in black and white 😭

I forget which video, but if you watch the full playlist I think I encountered this issue in the second video and discussed a workaround for it. Basically you want to launch the jar file from terminal and for some reason it works.

@@aura-audio nice, thanks man :D

@@KudaGaming83 Anytime, thank you for watching :) !

Fr, those are some of my favorite games of all time for that reason

@@aura-audio the thing i dont get is, if u are supposed to have only 2 direct sound channels and 1 sampler, why can i hear more than 3 instruments being played in pokemon emerald songs? where are they coming from if the rest of channels are 2 square + 1 noise? can direct sound channels reproduce more than 1 sound each?

Good question, it’s definitely possible with some programming tricks. The GBA hardware is close enough to the metal where you could play sounds using other Direct Memory Access and timers if you wanted to.

Hey, thanks for watching 🙌🏻! Have you checked out the full playlist of ROM hacking videos on my new channel @aura-hacks? If that doesn’t work, you can email me and we can set up a call or something evan@auraaudio.io

its fine i sort the problem out. Thanks for that fast respond tho! @@aura-audio

Will add it to the list once I have time! Make sure to check out my new channel @aura-hacks for more ROM hacking stuff. This channel is only going to have audio related videos from now on.

@@aura-audio ready, I found your channel friend, please don't forget that video, at the moment no one has taught me how to change the character sprites in gba!

Some of my later videos on there might be helpful. Later in the playlist I made a video showing how to change the graphics in Sims Advance. They're pretty long, but if you watch the whole video for each part, you will be rewarded with newfound knowledge 🙂!

@@aura-audio okay friend, but I will still be waiting for the final fantasy 6 from gba, greetings :)

Will add it to the list!

Thank you, and thanks for watching 🙏🏻🙌🏻! Absolutely, if I remember correctly sprites contain all of the tiles which make up a character. So it's a question of finding the ordering (sometimes referred to as the mapping) of tiles as I believe I show here.

Thank you for watching! Make sure to check out my channel @aura-hacks where I'll be posting more ROM hacking videos in the future

This channel is going to be moving towards more audio/music stuff

I'll definitely check it out!

Funny thing is, I am actually mildly colorblind (red/green). Second, to add context this was June 2020. My city was falling apart because George Floyd had been murdered there by a police officer who lived adjacent to my neighborhood. For some people it presented them an opportunity to take advantage of the city. Others peacefully protested. It was an intense time, and I thought by introducing music would help create a safe environment for people.

Would you be able to make a tutorial on how to rip gba music and deconstruct isolated tracks? I've seen gba deconstruct videos where they isolate the tracks from gba games. It's really cool but I don't know how to do it.

That's a great idea and I've been wondering too since I'm mostly a music person and ROM hacking sort of happened by accident. Lots of people have asked about it, so I'll definitely keep you posted if I find anything out and make another video 🙌🏻!

Thanks Nick! Oh I haven't heard of those before, but it sounds interesting! I bet they did or maybe some filter banks. That would be a great idea!

Thanks man 🙏🏻! I’m glad you enjoyed it!

Absolutely!

@@aura-audio Amazing! i just finished the tutorial and i cant believe it was so simple.

@@g43s Thank you for watching, I'm glad it was helpful :) ! For Ableton you should select the corresponding control interface in preferences, make sure All Ins and All channels is selected on the track and then arm the track for recording.

Yeah people have suggested that in the past and I haven't figured it out yet, but it's a good idea

That's a good question. Yes, by using the DMG (Dot Matrix Games) sound enable registers you can use the pulse signal channels from the original Gameboy: www.coranac.com/tonc/text/sndsqr.htm

It's a little tricky to learn, but once you know the registers you need to enable, sound on the Gameboy is actually pretty simple/direct which is why I like it so much

@@aura-audio is there a limit on the number of channels you can use from each chip? Or does using this effectively double the number of channels you can use at once?

Yah I think original pulse channels gives you 1 sweep plus another pulse generator without the sweep plus the noise/rumble channel for percussive sounds plus another channel where you can load in your own 4 bit wave table. Then with Gameboy Advance you get 2 more 8-bit channels. Pretty sure you can use all of them at once

@@aura-audio If there's only 2 8-bit GBA channels, how were tracks done that seem to play up to 4 or 5 samples simultaneously? Am I mishearing or is there a way of redistributing or assigning channels for different purposes depending on what's needed?

Any luck on trying the methods in my recent videos?

Ah bummer. What are you trying to do again? You want to change the character in the game?

The dialogue character avatar in the game, and the rest. I only wanted to create the character myself using materials after watching other people’s videos.

Ah I see, so you're trying to change the text at the bottom and some clothing or features of the character as well. Tell you what, if you want you can send me an email: contact@auraaudio.io. Then we can set up a quick 30 minute call and I can tell you everything I've learned. Does that sound good?

Thank you, I successfully changed the graphic

Hey, thanks for watching! Unfortunately it isn't possible on Windows since you do need Xcode, but Virtual Studio Plugins (VST's) are much more popular. I've been meaning to make a video about it soon but haven't gotten around to it yet since school has been busy.

@@aura-audio Many thanks, I cannot find any AUV3 tutorial or video, if you do make one I think it would be quite popular! I wonder can it be achieved swift playgrounds on IOS?

Thanks for watching, and great question! Yes, it's possible on a MacBook as well, but since MIDI is a network protocol, doing it on the same device your testing on wouldn't work through the MIDI network session if I remember correctly. What you can do is create virtual MIDI ports without the network session.

That would be a cool video idea! Do you know of any cool resources where someone makes their own linker cable? I could probably look up some DIY articles online as well.

@@aura-audio i still am really craving to learn how to do this with the new SwiftUI stuff... any chance of re-recording this? do you do any 1 on 1 teaching?

You're welcome :) ! Thank you for watching and I'm glad it was helpful. Lol it totally does, the drums are almost the same!

I would use an audio interface or preamp

@@aura-audio Thanks for the response! (And incredibly fast) But what do you mean exactly?

Record the sound directly from the headphone out on the GBA and route it through a preamp so when you amplify it the signal is clean. Google “preamp” and you will find many examples :)

​@@aura-audioAhh I see Thanks!

@@aura-audio I do wonder though 😅 Is it possible to emulate the sound chip on a computer?
