Kirby's Adventure/RAM map

The following article is a RAM map for Kirby's Adventure.

• 0042 = PPU sprite banks 0-1
• 0043 = PPU sprite banks 2-3
• 0044 = PPU background bank 0
• 0045 = PPU background bank 1
• 0046 = PPU background bank 2
• 0047 = PPU background bank 3

• 0593 - 0595 (0003) = score (1 per 10 points)
• 0596 = health (max) (count by 8)
• 0597 = health (current) (count by 8)
• 0598 = power (for mike, crash, light)
  • only used for display, except mike
• 0599 = lives
  • max of 63 (99 decimal)

• 059D = lives display
  • 00 = lives only
  • 01 = power & lives
  • 02-FF = [GLITCH]

• 05E2 = power of eaten enemy
• 05E3 = current power (see Notes)
  • NOTE: bytes for actually being able to use power are VERY COMPLICATED (627F 6291 62A3 / 62D9 62EB 62FD)

• 058C = background graphics cycle - current
• 058D = background graphics cycle - countdown
• 058E = background graphics cycle - type

• 62C7 = kirby state (see Notes)

• 67EE - 74C7 (0CDA) = current map data (see Map Data Format)

• 7A00 - 7FFF (0600) = current tileset data (see Tileset Data Format)

Tileset Data Format

Tileset data is decompressed to 67EE - 6D2D (0540), then decoded to 7A00 - 7FFF (0600)

Original format:

• 67EE - 6BED (0400) = tileset - sets of PPU tiles (4 bytes per full tile)
• 6BEE - 6C2D (0040) = tileset - palettes (2 bits per tile)
• 6C2E - 6D2D (0100) = tileset - attributes

Decoded format:

• 7A00 - 7AFF (0100) = tileset - top-left PPU tile
• 7B00 - 7BFF (0100) = tileset - top-right PPU tile
• 7C00 - 7CFF (0100) = tileset - bottom-left PPU tile
• 7D00 - 7DFF (0100) = tileset - bottom-right PPU tile
• 7E00 - 7EFF (0100) = tileset - palette
• 7F00 - 7FFF (0100) = tileset - attribute (see Notes)

Map Data Format

After the tileset data is decoded, the map data is decompressed to 67EE - 74C7 (0CDA) (no decoding necessary)

NOTE: Maps can have 1-16 different screens, and screens can be duplicated in the map screen order

• 67EE - 68C7 (00DA) = header
  • 67EE = map width
  • 67EF = map height
  • 67F0 = PPU background banks (see ROM 0x0B428)
  • 67F1 = PPU background palettes (see Background Palettes)
  • 67F2 = PPU sprite banks
  • 67F3 = PPU sprite palettes (see ROM 0x24E65)
  • 67F4 = music
  • 67F5 = background animation delay (00 = off)
  • 67F6 - 68C7 (0010) = map screen order (from top, by rows)
• 68C8 - 6987 (00C0) = map screen 1
• 6988 - 6A47 (00C0) = map screen 2
• 6A48 - 6B07 (00C0) = map screen 3
• 6B08 - 6BC7 (00C0) = map screen 4
• 6BC8 - 6C87 (00C0) = map screen 5
• 6C88 - 6D47 (00C0) = map screen 6
• 6D48 - 6E07 (00C0) = map screen 7
• 6E08 - 6EC7 (00C0) = map screen 8
• 6EC8 - 6F87 (00C0) = map screen 9
• 6F88 - 7047 (00C0) = map screen 10
• 7048 - 7107 (00C0) = map screen 11
• 7108 - 71C7 (00C0) = map screen 12
• 71C8 - 7287 (00C0) = map screen 13
• 7288 - 7347 (00C0) = map screen 14
• 7348 - 7407 (00C0) = map screen 15
• 7408 - 74C7 (00C0) = map screen 16
