People with 64k (lol@how much they would suck)
wtf? a little info:
8 Bit = 1 Byte
1024 Byte = 1 KByte
1024 KByte = 1 MByte
1024 MByte = 1 GByte
so, people with 64 K got other problems that their memory, pc with arround 20 Mhz (yes Mhz) of CPU Power would even get problems with extracting Blockland :P
if you mean 64 Mbyte RAM, lol, no problem 64 Mbyte = 65536 KByte
back to the topic: I also think it should be an option to set, and 1024 as default.
