Replacing Castle Siege

[toddtj]

Is there anything special about Castle Siege that I should know if I am trying to replace it? I see that it has 4 pacs. One is considerably smaller in size than most pacs(300 somthing kbs). I tried putting my replacement stage over the three normal size pacs, but not the small one: dimmed screen and silent freeze. I tried putting my replacement stage over all four pacs: dimmed screen and silent freeze. My stage was built on 75m(the name of the hack is Grand Stadium V3) and I have a rel to put 75m on top of Castle Siege.

Can anyone tell me what I am doing incorrectly? I only assumed that it's currently possible to put a stage on top of Castle Siege- if this is not true, please tell me.

Thanks


EDIT: OP updated with corrections detailed in post#2.

New Information:

It didn't freeze on a black screen- I recalled incorrectly. Both freezes occurred while the stage selection screen was partially dimmed as it was loading the stage. Also, I compared the rel's file size to the original stage rels and discovered that the stage is actually built on top of 75m.

With this in mind, I switched the rel file I was using, but still got freezing errors. When I replaced all four pacs I got a full volume(I think) beep when the stage selection screen dimmed to load the stage and when I only replaced the three normal size pacs I got the same silent freeze as before.


Note that I did not add this in an edit of the OP because I think this additional information is significant enough to warrant drawing attention.
