Basic Questions & Answers thread

For the first thing, you can look in the wiki's music hacking guide. For the second, you can set up a disassembly with soned2 (for sonic 1 and 2) and all the sound stuff will be in the sounds folder. Alternatively, you can use ESEII Sound Importer, to export s3k and s3d songs to .bin files.

 

Hey, once again I have another question. Well, I am going to post my hack up very soon, but I think it needs some layout fixes, and to change the colors of all the zones. When I use a palette editor, every time I save and run build.bat, its not there.
Why?

 

You're editing the split palette files right?

 

How do you change the background deformation of the Sonic 1 title screen? I need to change it from the GHZ deformation to any level which has a background that just goes left to right as one whole thing. I think LZ deformation would work well if I could just transfer it over.

 

The easiest way that pops in my mind is to go to DeformBgLayer and add something like
cmpi.b #4,($FFFFF600).w
to see if you are at the title screen, and then alter the value of d0 accordingly.

While I can easily provide you actual code to perform this check and replacement, I think you should try to achieve this result by yourself.

 

Hello again! Already I have solved this mistake, have used another (this) dissassembly and it me goes of marvel. But... I have another doubt. I try to put a song with the Xm3smps320, but my choice of channels FM, PSG and DAC is not the correct one, since in the game there are heard "strange sounds". How should it choose the audio channels with accuracy? Thank you in advance!
Note: This is the "strange sounds"

Spoiler

It is supposed that it should be Frog Forest's theme

 

Not really sure if this counts as basic, but it's as good a place as anywhere else.
What's the deal with mappings in split screen mode (Sonic 2)? Not just sprite mappings. 16x16 blocks are messed up, too (except for the zones that use split screen mode). Is there some kind of restriction on mappings in that particular screen mode? The wiki hasn't really been very helpful there.
While I'm on the subject, does anyone know what makes water levels crash during split screen mode? In the earlier betas it was possible to reach water levels and the game wouldn't crash.
I remember reading a discussion on split screen mode and water a few years ago, but I can't find it anymore.

 

Your first question is answered in a thread in the Tech Lounge, so I don't think I'm allowed to cross-post it here. I'm feeling kinda guilty as I voted against your tech membership when you were nominated, but still, Nemesis knows the answer. Try to PM him, I guess.

About your second question, the main problem is to switch palette 4 times per frame instead of the regular 2, as you have

Code (Text):

1. ?????????
2. ? a.w.  ?
3. ? u.w.  ?
4. ?????????
5. ? a.w.  ?
6. ? u.w.  ?
7. ?????????

Where a.w. stands for Above Water and u.w. stands for Under Water

edit: oooooooooooooooooook

 

Yesyes, I'm aware of the speed issues involved. The only reason I'd try to get water palettes working in split screen would be to see what it looks like (or if I found a way to make it work and still be fast enough).
My main point was that in the final you can't even get past the title card whereas in the Simon Wai beta it was possible to get the water palette to load even when in split screen (though it would behave like in 1p mode). Ergo, something must have been changed there.

Nah. I wouldn't want to bug him just for that.
Guess I need to level up some more.

 

Hello again! (Heavy what I am ... =D) I Have been trying to put the SpinDash, but in the moment to edit the tiles, in the editor they go out for me of a yellowish color with black fund. On having tested the ROM this goes out for me:

Sonic's Main Pose
What can I do?
Note: Oh, and I would like to receive response... If not, it doesn't matter.

 

To Joaki : There's a two part tutorial in the Retro wiki. You probably had messed up with the tiles that should match S2's tiles which is why you see that garbled mess

To Irixion : I've set up a disassembly using Hivebrain's. How do I get the sounds folder to appear while using SonEd2? Just need to know.

The music, specifically, should be labeled from music81.bin to music 93.bin (I'm pretty sure everything after that is sound effects). These are the musics in .bin format. I'm pretty sure that SonEd2 cannot actually edit or do anything with the music, but once you've set your hack up to use SonEd2 (to edit art or layout, and whatever else it does) you've already accomplished everything necessary to be able to edit the music (basically have a working split disassembly) using other tools (such as xm3smps or whatever other tools exist to do crap to the music).

 

Where are the tiles for Tails's tails in Sonic3?

 

Personally, I think posting general info from the Tech lounge, which may be useful to other people, is perfectly fine if someone asks about something. Of course if the poster's asked for it to be kept restricted to the Tech lounge, then that's something else, but otherwise IMO it makes no sense to keep stuff like that restricted to only certain people.

 

Ack. Now that I know what needs to be done, I don't feel so eager, anymore. It's not the kind of thing that's fun to do manually.

 

They're at $336620 in a Sonic 3k ROM, or $136620 in Sonic 3 alone. According to Stealth's disassembly, the size is $1160 bytes.

 

I'm not talking about information which should be kept secret, there's a lot of that. I'm talking about general hacking info, such as the one in question here (Nemesis' explanation of the special mappings format used in 2P mode). I really don't see any harm in posting stuff like that outside the lounge, especially since it's something I think quite a few people have asked about.

 

don't know why you flaunt that considering there is NONE. :P

thought I might show what things look like
