Hacks supported:
All!

A note about Super Castlevania 2 hack, on the hack file go to Hex location $05 and change
$08 to $10 and at ROM location $30010, in Hex Workshop, in Edit, go to insert and on the
Insert Bytes, insert number of bytes 10000 in Hex and fill the hex byte with 0's then save
the file. And now patch my MMC5 xdelta hack to your hack and now your hack will work with
my MMC5 hack.

Hacks not supported:
Castlevania II retranslation - Simon's Quest suomeksi
or
Castlevania II (Simon's Quest) - Multilingual enhancement

Use Delta Patcher to patch the xdelta file to the ROM. 
Ignore the checksum and then patch the file.
