way 3:auto refill cdkey, using multiple cdkeys (need d2loader)
first copy cdkey.mpq to your diablo2 folder.
edit auto-cdkey.reg, set:
"d2cdkeympq"="cdkey.mpq"
"d2xcdkeympq"="cdkey.mpq"
also set "d2cdkey" and "d2xcdkey" to the cdkey you want.
then import the registry file again and start refiller.
to refill both cdkeys.
then the new cdkey you set will be both stored in cdkey.mpq
(in diablo2 folder)
if you want to use this cdkey, start d2loader with option
"-mpq cdkey.mpq" (without quota)
e.g: i assume your diablo2 is in directory c:\diablo2.
create two shortcuts,
1: c:\diablo2\diablo ii.exe -w
2: c:\diablo2\diablo ii.exe -w -mpq cdkey.mpq
