Memory Map

The following is a memory map that was generated based on the MAME source code (.180). This information is only as accurate as the MAME driver is. If you see any errors, please let me know what that error is.

The Memory Area is related to where the information is from (CPU, Sound Board, etc..), and it may also reflect what it has in common with other hardware.

Xevios (bootleg, 1982)
