Kirby's Adventure/RAM map

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

• 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 (no decoding necessary)

• 67EE - 74C7 (0CDA) = decompressed map output
  • 67EE - 68C7 (00DA) = header
    • 67EE = map width
    • 67EF = map height
    • 67F0 = [PPU 0 banks]
    • 67F1 = [PPU 0 palettes]
    • 67F2 = [affects PPU 1 banks]
    • 67F3 = [PPU 1 palettes 2-3]
    • 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
