Awesome update, couldn't get any better

Gotta love those two stories houses

I see you not only took time to include some custom fixed corners GFX but also some nice water coming outside the middle place!


I have no doubt about the future sucess of this hack, it'll surely become another classic must play hack. You can easily see it by the quality of work.

Keep up the good work NS

Now off to bed, at long last.. hehe.

subscreen:
a few useful addresses are:
$0D/DDAE - drawing routine (when start is pressed)
$0D/DF88 - refresh routine (drawn every vblank in menu)
$1100 - i think it's about here is the start of the DMA transfer addr to vram.

enjoy.


He might have more but then he might just reply in there


Well that's about all you need to redo that bg3.

First thing is you need to know the ram space which it's used to draw on before it goes to the vram, which is there, secondly you need the code place which refreshes what you see during each vblank, which is also there.

The rest are just knowing what those JSRs are doing and modifiying it a lot to do what you want it to do, it'll take too long to explain what each one does but... if you know anything about how tiles are stored in vram then you'll do fine.

The great thing about that area of code is that the programmer which done is has been quite lazy, unless you're asking for a lot of details you wont' run out of space to write code in (i mean you can just take it and rewrite the code in more efficient manner and have space leftover for your own use, if that fails you can always consider the end of the rom....)
