"The Sega Master System is an 8-bit cartridge-based video game console that was manufactured by Sega and was first released in 1986. Its original Japanese incarnation was the Sega Mark III (although the "Master System" name has also been used in Japan).

In the European market, this console launched Sega onto a competitive level comparable to Nintendo, due to its wider availability, but failed to put a dent in the North American and Japanese markets. The Master System was released as a direct competitor to the NES/Famicom. Despite its shaky performance in the major territories, it has enjoyed over a decade of life in smaller markets."

What are Goodsets?
Goodsets are sets created by Cowering's GoodTools, a renamer program that has the ability to "see past" the headers attached to many console ROMs. These tools are fairly comprehensive but have not had many updates in the last year. File naming is not always accurate, but these are great "starter sets". They look to catalogue every known ROM of every game. Since each game can be packaged with goodmerge, there's is usually a very small increase in the collection size. Since No-intro uses zip, their sets tend to be larger than the 7zipped goodsets ( great example of this is the N64 set... the no-intro set is ~10gb where the goodset can fit on a dvdr ).
