At start:
r0 = "where to load" address, gets stored in [sp]
r1 = "where to store" address, gets stored in r5
r2 = "darkening factor", gets stored in r6
r3 = number of colors to do, gets stored [sp, #0x004]

[sp, #0x008] contains the counter of how many colors have already been edited

r4 contains the value out of [#0x03C] (halfword, 16 bits)

r7 contains the value out of [#0x038] (halfword, 16 bits)

r12 contains the value out of [#0x034] (halfword, 16 bits)

normally, r4, r7 and r12 are zero. Its the color to (or, from) which everything should fade, so if they are all zero, it's black

$0801C8B4 - Rectangle BG mapper

THIS SUBROUTINE can set a certain space to one value (this feature is optional) and can set a rectangle shaped field in this place. Something like this:

$0A, $0A, $0A, $0A, $0A
$0A, $20, $21, $22, $0A
$0A, $23, $24, $25, $0A
$0A, $0A, $0A, $0A, $0A

The length and the number of lines is set on the stack. I think the value that's the starting value for the increment (I mean, in my example, $20) gets transfered into this subroutine, too

1C-1F r4 18-1B r5 14-17 r6 10-13 r7 0C-0F Link Register 08-0B r8 04-07 r9 00-03 new entry

r0 contains a destination address for a "swi CpuSet" r1 contains a half-word-value that gets fixed-transfered --- the one value that fills the space r2 contains the value the upcounting should begin with (half-word size!)

The result this subroutine is stored in r2, r0 contains a counter.

$080972B4 - (Main Title Subroutine?)

As far as I can see, this is only called from $0800052E. The value that is in r0 in the end is used as a number for a Jump Table, something between #$00 and #$06. It is loaded here at $08097376 onwards from Register $020326D1.

$080977CC - Set Video Mode (Titlescreen/Intro)

This Subroutine can do three different things:

1) It sets the system to Video Mode 0

2) It sets the system to Video Mode 2 and clears all registers for Video Mode 2

3) It clears all registers for Video Mode 2 without setting Video Mode 2; I expect this to be used when it is sure that everything already is in Video Mode 2

This subroutine is controlled through a jump table. Funny fact is there are different jump table entries pointing to the same address. The only logical reason for this is that the variable for the Jump Table is periodically incremented and not set to a fixed value.

$080978F4 - (Graphics Buffer clearing?)

When this is called from $080976DC (I don't know if it is ever called from somewhere else), r0 contains the value from $0202DE34, which is the address of the graphics buffer (should be $0203CAD0).

This is only executed once, when the Intro is first loaded.

$0203E9D8-A get all get set to #$1F, $0203E490 = #$7FFF (set Color No. 0 in the Palette RAM buffer to white)

$08097A50 - (Register clearing, jump to Register Setup)

(As far as I can see it, this subroutine is only called from $080976DC. In that case, r0 is always = #$0202DE44, so I wrote all the comments here under the assumption that r0 = #$0202DE44. In the unlikely case that this is executed from elsewhere with a different value, you have to re-calculate the corresponding addresses.)

This subroutine

  • clears a whole lot of addresses
  • Sets $0202DEBA to #$00 or #$01, depending on the corresponding status of Bit 0 of $0203CAA2.
  • Jumps to a subroutine

$0809820C - Screenfilling Tilemap Builder

This is a Tile Map builder. It builds a tilemap sized #$1E*#$15 Tiles = 30 * 21 Tiles (for 8px-Tiles, this is 240*168px; GBA has resolution: 240×160px)

r0 contains the Data Load address.

r1 contains a value (valid between #$00 and #$03) for the Data Store address; it's the number of the BG the data is for.

r2 contains an double byte that gets added to each tile (like, set all the tiles to a certain palette)

$0809824C - Screenfilling upcounted Tilemap Builder

This builds a Tilemap. The Tilemap consists of values that increment per Tile. This always starts at the first Tile of a Tilemap and creates a #$1E*#$14 Tilemap. With 8px-Tiles, this is exactly screenfilling.

r0 contains the number of the Destination BG.

r1 contains the value the first Tile should start with (gets transferred in r4).

$080989E8 - ?

r0 contains an address. The Data at that Address starts with it's destination (as a 32-bit-address), followed by the actual data (#$40 Bytes). This gets transferred with a DMA. Behind the Data are 48 Bytes(?) of additional Data for this subroutine (settings?).

$15 (twenty-one) DMAs are executed here, but after each time, the destination address gets #$20 added, while the Source address gets #$1E added, so each time, a 2 byte gap is created.

Maybe used for Palettes?

$08099BB8 - Jump to Subroutine Address Table Entry

Besides some other settings, this subroutine jumps to a subroutine at the Subroutine Address Table at $0869948C. That table is really big (about three hundred entries).

r0 contains an address. (In Intro, it's $0202DE44 and seems to always stay the same everafter)

r1 contains the number of the Table Entry where to jump.

$0809B6D8 - (Double Mini-Flexy-DMA)

This performs two DMAs of #$40 Bytes in size.

r0 contains an address r1 contains the DMA destination address (minus #$04...?!) r2 contains a doublebyte-sized value relevant for forming the Source address

Bits #$0 to #$3 get, kind of, multiplied by #$40 and added to the Source Address Bits #$4 to #$F get, kind of, multiplied by #$800 and added to the Source Address

r0 contains the BG number, r2 contains the Y-coordinate, r1 contains the X-coordinate. This turns these values into the address of that tile in the Tilemap buffer in WRAM.

The main difference between this subroutine and the one at $080BD5E0 is that here the basic offset is loaded from $0202DE34.

  • sets up the Random Number Table (I guess...?)
  • turns $0203BB4D to #%????.?010
  • sets r2 to $0203BB4E's value (and clears Bits: #%????.000?)
  • turns $0203BB51 to #%??00.????
  • sets r2's Bit 3 according to $020326F0's Bit 16 (aka. $020326F2's Bit 0)

$0809EB6C - ?

This is called from $080A7BE8 and $0809EA38 (maybe from others, later, too). In both cases, r0 contains the address $0203642C.

With #$0203642C in r0, this subroutine does:

  • Set bit 0 in $02036546
  • Store #$00000000 in $02036538-B.
  • Store #$003C in $02036534/5.
  • Store #$00000000 in $0203653C-F.
  • Store #$00000000 in $02036540-3.
  • Store #$FFFF in $02036544/5.
  • Clear bits 1 to 4 from $02036546.
  • Store #$0068 in $02036530/1.
  • Store #$0038 in $02036532/3.
  • From $0203642C to $0203652F(?), this fills the register in the following pattern: $???????? $0080 $0080 $00000000 ($00013B13 * Loop Counter) ($0001 * Loop Counter). First byte is not changed.

$080A9318 - ?

This is called from $080A7BE8 (maybe from others, later, too). Coming from $080A7BE8, r0 contains the address $02032714 and r1 = #$00.

In that case, this subroutine does the following:

  • It stores #$FFFF in $02036120-F
  • It stores #$0001 in $02036130-F
  • It stores #$00 in $02036156
  • It stores the value that was originally in r1 in $02036157 (here: #$00)
  • It stores #$00 in $02036158
  • It clears Bit 0 in $02036159
  • It stores #$0000 in $02036140-7

$080A93BC - ?

This is called from $080A7BE8. If it is, the address in r0 is $02032714.

In that case, this changes the registers between $02036018 and $02036057. It sets two byte to #$FFFF, leaves two byte out, sets two byte to #$FFFF again and so on. After that, it jumps to an address from a jump table.

Other register values on the first call are:

r1 = #$00000001

r2 = #$00000001

r3 = #$00000000

This subroutine does:

  • Add a new entry on stack, temp store r2 and r3 there
  • Clear Bits 1 and 2 of $0203CABC (r0 + #$0EAC)
  • Clear #$E94 bytes from $0203BC10 (r0) on
  • LEFT OUT IF r2 = #$00: Call of $080B74E0 (SRAM-related)
  • LEFT OUT IF r2 = #$00: Set Bit 0 of $0203CABC (r0 + $00000EAC)
  • LEFT OUT IF r2 = ? (Some weird is-Bit-Set-testing and branching)
  • LEFT OUT IF r2 = Transfer #$18 bytes from the address in $0203F3C4 to $0203CAA4 (r0 + E94)
  • Check if $020000E4 = #$0800170D or #$08001719. If it is, leave out next point
  • MAYBE LEFT OUT: $0203F3AC = r0 (#$02), $0203F3B4-7 = #$04000108, $020000E4 = #$080BFB0D

$080B6E98 - ?

r0 contains an address. r1 and r2 contain byte sized values.

Through testing, I found out that this has to do with SRAM writing. This is only executed if the Save Data is corrupted (or non-existent). r0 (and later r6) contain #$0203BC10 then (SRAM Buffer?).

$080B74E0: - Is r0 empty?

My new comment:

r0 contains a double byte. If this double byte is empty, r0 gets set to #$01. If it's not empty, r0 is set to #$00. Consider this as: "Is r0 empty?" - Yes (1)/No (0)

My old comment:

; IF THE SIXTH VALUE FROM THE DATA SET -THE ONE THAT WAS STORED IN $0203F3C4 - IS #$xxxx0000,
; r0 IS SET TO #$01, ELSE IT GETS SET TO #$00

$080BBE70 - (Put a Super Randomized Number in $0202DA08/9?)

The first bits seem to me like they try to form a super-random number in this newly added Stack entry.

r0 and r1 contain addresses.

This is much more complicated than it has to if you need a Random Number. Whatever. The Random Number is stored in $0202DA08/9 in the end.

$080BD5E0 - Calculate address of a tile ($02032704)

r0, r1 and r2 contain number values.

First of all, an address is loaded from $02032704. Then the calculation goes address + r0 * #$4B0. Valid values for r0 are #$00 to #$03. Then the values of r1 and r2 are changed a bit and added to the address.

I expect this to be used this way:

r0 = BG Number

r1 = Tile Column Number (X)

r2 = Tile Row Number (Y)

The calculation is final address = (address in $0203704) + 2 * (30 * r2 + r1). The screen can contain thirty 8x8 tiles (240px Width), and each tile has two bytes data, so the calculation actually is:

Final Address = Offset + 2 Bytes per Tile * (Number of Tiles per Row * Tile Row Number + Tile Column Number)

The main difference between this subroutine and the one at $0809C36C is that here the basic offset is loaded from $02032704.

$080BDD28 - (DMA to Tilemap Buffer?)

This does a DMA to the Tilemap Buffer, if I get this right.

r0 contains the Source

r1 contains MAY BE the number of the BG it should go to

r2 contains the number of single Bytes(!) to transfer

$080BDF70 - ?

This has some similarities to $08098484.

  • This disables interrupts
  • transfers the Data at $020000D0 to $0203BB68
  • then replaces the Data at $020000D0 with Data from the address that is in r0
  • starts a DMA that transfers #$800 byte from memory to WRAM
  • Stores the Address where the data is sent to in $03007FFC
  • Re-enables Interrupts

$080BE330 - Load LZ77 Compressed Data Table Entry

r1 contains the number of the Table entry. This gets multiplied by 4 (each entry is 4 bytes in size - 32 bit addresses) and added to the address in r0 (which is the Table offset). The entry that is four byte further is loaded (See line 080B3336, "r1, #0x04"), which is added to the Table Offset. The result is the address of the LZ77 compressed data, which is stored in r0.

$080BE8E4 - Timer

r0 contains an address, as far as I've checked, it's always $0203BBF0.

r0 + #$10 ($0203BC00) = Big Timer (incremented each time the Small Timer runs out)

r0 + #$11 ($0203BC01) = Big Timer Goal value

r0 + #$12 ($0203BC02) = Small Timer (decremented each Loop)

r0 + #$13 ($0203BC03) = Small Timer restore value

Note that this subroutine itself does nothing, no Flag Set or anything, when the big timer runs out. So, when this subroutine is used, it has to be checked if r0+#$10 = #$00.

$080BF2E0 - (Give out Random Number?)

I think this is a Random Number Generator.

$0203F3A0 contains the "controller" for this. If $0203F3A0 is less than #$270, it serves as an Index, which Random Number of the Random Number Table should be given out. Afterwards, $0203F3A0 is incremented. If it reaches #$270, the whole Number Table gets mixed up again. #$271 is the signal to set up the Random Number Table in the first place.

The Random number is given out in r0.

r1 contains an address. In that address "#$080BFB0D" gets stored.

r0 contains a timer number, so it must be between #$00 and #$03. If its higher than that, this subroutine exits. In the end, bit 0 of r0 is used as a flag: If it did not work, that flag is set; if everything's fine, it's clear.

This subroutine stores the timer number byte (#$00-#$03) in $0203F3AC and the Timer Counter/Reload Register ($04000100, $04000104,...) in $0203F3B4.

$080BFDEC - Check Data transfered from SRAM

This transfers a Subroutine from ROM to WRAM (stuff in WRAM can get executed faster) and jumps there.

This compares stuff from SRAM with something different. In the Intro, this is used to compare data that was transfered from SRAM to WRAM before ($080BFD40) with it's original material, so it checks if the transfer worked without any mistake. If a mistake happened, r0 contains the (WRAM) address of the byte that differs. If everything worked fine, r0 = #$00
