The code below has some issues so don’t use for now.

If you just want the prep screen without having to go to castle (i.e. before castle is unlocked), you can set the below in paragon:

WIP CODE

Making use of the ‘add ev:: commands’ hack from the above post, here is a new command to allow skip castle while still saving between chapters

https://cdn.discordapp.com/attachments/354835401904619531/995162616395731057/Skipcastlewithsave.mp4

    ev::ChapterSetSkipChapterSaveCastle(1); //original, skip both save and castle
    ev::ChapterSetSkipCastleWithSave(1); //new, save and then skip castle

Default behaviour:
if 0x1000000 set, skip save and castle and go to next chapter (used for e.g. endgame part 1->2)
else if 0x800 set, skip save and go to castle (used for castle defense?)

New behaviour:
if 0x1000000 set, skip castle
if 0x800 set, skip save

magikoopa hooks:

ReplaceevChapterSetSkipChapterSave:
    type: symbol
    addr: 0x426428
    sym: SkipCastleWithSave

ReplaceBeforeSaveRoutine:
    type: branch
    addr: 0x1b66fc
    link: false
    func: CheckSkipCastle

ReplaceAfterSaveRoutine:
    type: symbol
    addr: 0x53a1ac
    sym: PostSaveRoutine

asm (includes the callroutine ev:: code from prev post because it’s all part of the same expansion of event commands):
