Chip tiny.png The following article is a RAM map for Wario Land: Super Mario Land 3.

RAM Purpose
A000-A017 save game slot 1. The first 4 bytes (header) always equals to 0x19643957. When player enters the pipe, bytes in A004-A017 are copied to A804-A817.
A020-A037 save game slot 1 (copy)
A040-A057 save game slot 2
A060-A077 save game slot 2 (copy)
A080-A097 save game slot 3
A0A0-A0B7 save game slot 3 (copy)
A0C0 save game 1 checksum
A0C1 save game 2 checksum
A0C2 save game 3 checksum

A9AB level animation mask. Internal timer (A905) is ANDed with that mask. If it's equal to zero, level animation counter (AC88) is incremented. This allow to control level animation speed (eg : lava).
A9E3 indicate the type of (!) block to process after a door has been used. To be used with A9FE. 
     01 : (!) block 0x39 
     10 : (!) block 0x32

Once a door is used, the flag is reset to zero.

A9ED similar to A9E3, but for (!) block 0x38. This type of block is not used in any level and does not seems to have any effect.
A9FE indicate if any (!) block has been set
