Re: Gold Titlescreen Editing

Gto the offset 62B0 with a hex editor and type in 00 until you get to the offset 62EE. "0x" in front of the offset tells you that the offset is in hexadecimal system (the offset would be different in decimal system (0x62B0 = 25264)).

62EE has to be 00 too?
------------------
&h in front of the offset is the same thing as "0x" above but AgiXp is programmed so that you've to write &h for it to work.
115D8CF is one possible offset where you could put the titlescreen in.

So i can use 115D8CF too?
---------------------
let's say my offset is  CFE61, ok i am sorry but that didn't make sense .
how can you exactly calculate this:?[Offset] = [Bank * 0x4000] + [Pointer MOD (0x4000)]
you could tell me how to calculate the offset into a pointer calculator?
------
And let's continue with the tutorial :
Now open your rom in a hex editor and go to 0x62b0 and type 21 xx yy 11 00 88  3E zz CD F0 0A  - xxyy is the last 2 bytes of the pointer e.g. 0040 and zz is the 1st e.g. 29

xx is the Bank * 0x4000?
yy is the Pointer MOD 0x4000? and again how to get those numbers?

---
and forward of the tutorial doesn't look to much challenging.

Re: Gold Titlescreen Editing

Let's say that your [Offset] = 0xCFE61

[Bank] = 0xCFE61 / 0x4000 = 0x33

[Bank * 0x4000] + [Pointer MOD (0x4000)] = 0xCFE61
--> 0x33 * 0x4000 + [Pointer MOD (0x4000)] = 0xCFE61
--> [Pointer MOD] - 0x4000 = 0xCFE61 - (0x33 * 0x4000)
--> [Pointer MOD] = 0xCFE61 - CC000 + 0x4000
--> [Pointer MOD] = 0x7E61
--> [Pointer] = 0x617E
--> [zz] = 33, [xx] = 61, [yy] = 7E

This isn’t quite right. Modulo is an operator, like + or ×. It’s often represented with a “%” symbol, and represents the remainder (like ÷ represents the quotient). Byte‐swapping is a separate issue.

To convert a pointer ZZ:HHLL to an offset:
Offset = ZZ × 0x4000 + HHLL − 0x4000

To convert an offset to a pointer:
ZZ = Pointer ÷ 0x4000
HHLL = Pointer % 0x4000 + 0x4000

How to represent a pointer in bytes varies. HHLL is almost always swapped to LLHH. ZZ can be put at the front, put at the end, or left out completely, depending on how the code treats the pointer in question.

Re: Gold Titlescreen Editing

3. to the titlescreen? :/ yes that is easy.
you need a no$gmb or a bgb, they have a palette viewer.
It will show you the palettes of the titlescreen,And you
must insert the numbers of a palettegroup backwards.
If it is C753 then you write it 53C7 in hex editor.

Re: Gold Titlescreen Editing

In addition to this, MeanMrMustard has written an asm tutorial about editing the title screen.

a) Titlescreen ASM TUT:
Let's write a titlescreen for Pokemon Gold!

Find some free space and insert your AGIXP Picture.
You can have 255 Tiles on screen.
So open up paint and draw your titlescren then insert it anywhere you like.

Find some blank space in the rom and input this code!

Turn Screen off:
3E 63 ld a,63
E0 40 ld (FF00+40),a ;lcd ctrl

Get Pallete:
06 0C ld b,0c
CD 85 35 Call 3583

Load GFX:
21 xxxx ld hl,(2byte GFX pointer)
11 yyyy ld de,(Tile Space - either 0088 or 0090)
3E zz ld a,(gfx bank)

Load Tile Arrangement:
21 xxxx ld hl,(2byte to tile arrangement - must be in same bank as code)
11 A0C3 ld de,C3A0
0E FE ld c,FE

Play Music:
21 xxxx 2byte Music byte
CD 98 3D Call 3D98

Turn Screen on:
3E E3 ld a,E3
E0 40 ld (FF00+40),a ;lcd ctrl

Wait for Keypress:
CD 31 0A Call 0a31
C9 Ret


Now you need to point to it!
At 6250 type in the 2byte pointer to the code! or type in a pointer to this code:
21 xxxx 3e zz CF C9 x=2byte pointer to code zz=bank - This way you can have the titlescreen in another bank!

Re: Gold Titlescreen Editing

Yeah thats another version of the title screen tutorial from mean mr mustard. Seems he could never quite make up his mind on how to explain it as he changed his methods haha. This way might work better actually though.

That won't work at all. First off, you not only turn off the screen, but edit other properties as well. Second of all, this will not turn off the screen anyhow. You can only safely turn the screen off during vblank, so you first have to wait for vblank!

11 A0C3 ld de,C3A0
0E FE ld c,FE

You're missing the actual calls here.

Again, this should use bit-masking to turn the screen on, just like you should use bit-masking to turn it off.

cYa,

Re: Gold Titlescreen Editing

Thanks for pointing those out Tauwasser. As usual, MeanMrMustard leaves things out and doesn't explain as well or as accurately as he would like you to think in "tutorials" he posts places.

Re: Gold Titlescreen Editing

by the way, i made a post on facebook about this: I forgot that my normal email is associated with a second facebook I made, and my british hotmail account is associated with my real one. I don't know how that mixup happened, but I posted a link to my actual profile from the secondary one. Also if you want to skip straight to it and find my normal one, use zoot_suit_riot@co.uk  OR   mwhaley34124@troy.edu

Re: Gold Titlescreen Editing

It doesn't actually have to be one particular height, if you don't need that many tiles to draw it. For example, here is the image for an old version of SaR.

example1zq.png


Another example, here is the image for a more current copy of SaR

example2w.png



But basically, you have at maximum this much room to insert graphics, if memory serves:

It’s nothing on the forum end. It’s either your connection or the image host’s connection.
