Can someone rip my old stuff? :)

I just found probably the first thing I did release on the Amiga, it's pretty terrible but I still want to look at the sourcecode.
http://janeway.exotica.org.uk/release.php?id=4460

I obviously did my best to obfuscate it back in the days (have no reason why ) but I can't decrunch it.
I did like an old tool "Exelink" back in the days that allowed you to link several exe's to eachother so I think I might have done something like that to make it difficult to decrunch.

Anyway, anyone knows of a clever way of decrunching it? I tried some XoXo-tool found on Aminet but it didn't make much sense to me..
Thanks in advance

Had 2 minutes to spare. It was linked 2 times and the real binary was crunched with PowerPacker. Decrunched intro attached.

I've "resourced" it and trying to make it AGA-compatible, pretty fun, digging into my old code.
But working with "Resource" isn't that fun, is there some kind of "best practice"-way how to use it? I've successfully managed to resource my old code but it was kind of a slow process (with my "skills" anyway ).

Load executable, press "Disassemble", fix wrong/incorrect stuff (jump tables, data detected as code and vice versa etc.) manually.

Creating a proper disassembly can be quite tedious and it always needs a bit of time. However, for simple intros it shouldn't take more than some minutes to have something that is usable.

I don't have the program in front of me right now but I usually pick something "create labels" that translates "bsr lbl0000+$13" to "bsr lbl0013" or something. But I have to pick this multiple times since it doesn't do the entire program in one run.
Is there another way to do it?

Unfortunately not. Simply create a hotkey for that and it can be done quite quickly. It also helps to use "Disassemble" again after you manually created some missing labels, ReSource will then create more labels. Don't ever use that if you disassemble absolute address code though, in that case you really have to be careful which labels to create.

Once you mark something as code it should be enough to do another "disassemble" and it will make the labels by itself. (AFAIR - been a while since I used it properly.)

No, that's not enough. It will not create all missing labels.
