I converted Green Hill Zone to "S3&K" with level converter...now what?

I also only have the S&K disassembly, cause that's what the Mercurial had. I just want to try building that disasm with that converted level in the place of Mushroom Hill Act 1, just to see what would happen. But I haven't a clue what I'm doing here.

Actually the Mercurial disassembly is indeed the S3K disassembly, though you can build S&K. IIRC, you have to first spilt the two games by clicking "split s3k.bat",and then you'll have s3 and sk. Then place GHZ's data in the appropriate folder (Levels/GHZ if you have created a folder for GHZ which I assume you did. ) Then build the ROM. (And this way if you wanted GHZ to be in S3K, you can build S3K complete so it's not just S&K.) However, I've never tried out MainMemory's level converter, so I'm not sure if you'd run into some issues with the data. :\

I have a fairly simple question.

I am working more on that giant motobug boss that I posted a little while back, but I want to do something more with it. I won't go much into details, but here is what I want to do for right now.

I want the boss to check for if it has reached a certain point on the screen, and branch if it has not.

I tried something like this

        cmpi.w	#$29C0,x_pos(a1)         ; Is the boss at this location on the map?
        bgt	+                        ; if not, branch

However, this does nothing at all. The enemy is loaded at a1, and set at a greater x position than the check at first. Any help would be appreciated.

Where is this code located? You don't show where you set a1, so I can't tell if it's initialized properly. If this is in the boss object's code, the object should be in a0.

What do you mean by "this does nothing at all"? What is it supposed to do? If you don't have any better debugging tools, try putting an ILLEGAL instruction at the point you want to reach and when the game crashes with an illegal instruction exception, it means the branch was taken.

[Hitaxas]

Basically, I replaced the routine that loads the original EHZ boss, which does load the boss at a1. And to be a little more specific, the problem isn't that it doesn't do anything. But rather I cannot figure which branch condition to use, I want to check if the object has reached that position on the screen, if not branch. If so, stop all horizontal movement.

That is how this is set up currently.

So you load the boss at position $2AFE; why bother checking if its position is higher than $29C0? You already know the result beforehand.

You would start by replacing MHZ's files in the Levels folder with the files you got from LevelConverter, then... I'm not sure. I've never ported a level to S3K.

The thought behind that was if the position is higher, branch and ignore the lines following.

I changed loc_E6EE to look like this, which I thought would work better, but nothing happens when the boss reaches $29C0.

You are basically persisting on the same error; you missed my subtlety, which is partly my fault for being too terse and cryptic, so let me elaborate: the code you gave creates a new boss at position $2AFE whenever it runs; immediately after creating this new boss, the code compares the position of this newly created boss to $29C0 and branch if the boss' position is higher than this (that is, always). You are always creating a brand new boss and using its position; you are never checking the position of the true boss. Thus, the code will never work as you intend it to.
For it to have a chance of working, you have a couple options: you can either scan SST to find the boss object; or you can save a pointer to it in RAM after you create the boss, loading it back to check its position; or you can move the check into the boss' code.

After Routine3 creates the boss, it also increases the routine counter by 2, so the eventual Routine4 will run on subsequent frames. Unless your boss should react to something that is handled in the dynamic level events, you should really put code of this nature in the boss object's code instead; that way, you won't have to find the boss in object RAM. If you really want or need this code to be in the DLE, put it in Routine4.

Sorry if this has already been answered. But how would you add more levels to Sonic 2, 2 player mode. Say I wanted to add Oil Ocean Zone how would I add it.

Thanks.

[TheInvisibleSun]

I searched for the answer to this but I couldn't find it anywhere; it seems like a pretty basic thing though, strangely. How does one "Add a Palette to the Palette Index", and "Call the number out in d0"? Couldn't find the answer to this, sorry if I just made a simple oversight.

[Machenstein]

Is there a way to edit Sonic Advance's title screen?

[Ravenfreak]

From the hacking guide, it looks like most art is uncompressed, so you could probably open it in TLP or similar art editing program. Though you'd have to find where the art is located, as it's not listed on the guide on the wiki. :\

[Trujin]

So I've recently took up hacking again. As a beginner I've depended entirely by the "SCHG: How to" guides. All seemed well, until... OH SHIT!



Now, this seems like an easy fix, but I'm stupid so HALP PLZ? I've undone everything that I had recently applied. But still, same problem. I even went for the copy that I made and even that shares the same problem. So basically, I've fucked up! If there's a lesson to be learnt there, it's that you cannot make enough back-ups in case issues like this ever surfice.

EDIT: I managed to fix a problem with the ring sprite. But now Sonic is totally invisible. I'm just going to leave the it alone until I get some help.

Sorry for the n00by question, but how do you get SADXMDL to work, I tried opening my .exe file, but for whatever reason it always brings up an error that says "Arithmetic operation resulted in an overflow". Anyone know how to get it to work?
