Segment 0x02 constant location - Contains image data for the hud symbols and other textures. The segment is allocated by a hardcoded routine on startup. |

Table with segment-offset pointers to the HUD symbol textures. Since some of the HUD symbols were removed in the USA release, some of the slots are left empty:
8006C6CC 00000000 - J
8006C6E8 00000000 - Q
8006C6FC 00000000 - V
8006C704 00000000 - X
8006C70C 00000000 - Z
You can restore the old symbols by patching in the images from the Japanese ROM, and modifying the pointers in this table. |

Function that assigns ram segments
Arguments: A0 = segment number, A1 = ram address
Returns: V0 = 0x80-prefix-less ram address
Essentially just: *(uint32*)(0x8033B400 + segment_number << 2) = ram_address & 0x00FFFFFF; |

DmaCopy(u32 dst, u32 bottom, u32 top);
dst being the RAM offset! bottom is the beginning ROM offset to copy the bytes and top is the end.
Takes three arguments.
Example:
ADDIU SP, SP, $FFE8 ; -24 to stack. Aka, make space.
SW RA, $0014 (SP) ; Push return address to stack.
LUI A0, $8034 ; Upper half address.
ORI A0, A0, $269D ; Lower half address. A0 = $8034269D
LUI A1, $001C ; ROM offset start (bottom)
ORI A1, $0D60 ; Lower part, A1 = $001C0D60
LUI A2, $0020 ; ROM offset end (top)
JAL $80278504 ; Jump to subroutine DmaCopy
ORI A2, $00D1 ; Is executed before JAL. Lower half.
LW RA, $0014 (SP) ; Load back our lost return address.
JR RA ; Jump to return address.
ADDIU SP, SP, $0018 ; Restores stack. (+24)
DmaCopy basically copies data from ROM to RAM. dst is the destination (as RAM offset), bottom is the start (as ROM offset) which is copied to RAM and top is the end. So, in our above example bytes from $001C0D60 (ROM) to $002000D1 (ROM) into $8034269D (RAM). |
