Another issue I found this morning: I think still related to custom canvas size.

I have a 32x26 and when saving as a .map without attributes, I get a file of 892 bytes instead of an expected 832 bytes (32x26).

However, the option “Saving canvas as ASM” gives me the correct amount of bytes (832).

I inspected some the hexdump of the .map file and line 300 to end of 330 are expected, however anything beyond that (FF, FF, 33…) …. ah.. As I am writing this I get it. These are the attributes that shouldn’t be exported since the option is deactivated.
