not that im aware of, unless you are planning of building one rom dumper youserlf :D..but it's not an easy task (even if quite interesting :)) i suggest the GB transferer II also because it's the only one i know still sold on the internet
HKEMS is the original manufacturer of the GB transferer 2 :D...so i guess you can trust them!..otherwise another option is :
djtransformer.com/shop/product.php?id_product=19
i bought it there in december 2011 :) they still have it!
bye!
