| Yes, it is used by the locked door blocks. It's also used by LevelASM. Neither of which are part of the original game, and both of which can be modified to repoint to other RAM addresses easily enough. | |||

| That's one of the problems with ASM hacks. There's no real way to keep track of what uses what RAM address. (A list could help, but everyone would need to put their addresses in it, and they might not.)
However, most memory maps mark what appears to be free space. Those filled with 0x55 are never touched by the game. |

| So... We'd better get them while there still are any left?
I claim 7EC7F0-7EC7FF, and probably 7EC7D0-7EC7EF too. |

| That won't do much good without some sort of official database. Best bet would be to mix it into an existing address list.
Also you can't just say "I might use 7E0000-7FFFFF someday so nobody use them" or whatever, that's not fair.  |

I usually specify which addresses my hacks use in their READMEs, just in case a conflict arises. I should've known $7E010B was already claimed. 
Technically, $7E0100-$7E01FF is the stack, but SMW doesn't even use 1/4 of the space. Just to be on the safe side, I wouldn't go past $7E0180, but that still leaves you with over 100 bytes of free, uninitialized (i.e. never cleared) LowRAM. Hello, absolute addressing! 
I've also found a few more spots of free RAM in the first 8K. There are a few unused addresses somewhere between $7E00F0-$7E00FF (direct page!), and $7E0660-$7E06FF appears to be unused during the majority of the game ($7E04A0-$7E065F is the HDMA table used to draw the "zoom," keyhole, and message box effects). |

To get the number of digits exactly, take 1+log(2^1048576) (which is equivalent to 1+1048576*log(2)) and round the result down. So I get 315,653 digits -- pretty darn close to what you got, though. [/math] Getting back to ROM hacking, didn't someone already set up a database for SMW addresses (or was it just for commenting the assembly code)?... I remember seeing a link to one ("Open Source SMW" or something like that) in the last incarnation of these forums, but I guess it didn't really catch on?...
