Microsoft MSX rom alts, there is a ton. Is there a best overall single choice option or are they all worth keeping? Ex. the no-intro set has Galaga (Japan), Galaga (Japan) (Alt 1), Galaga (Japan) (Alt 2). Are the (Alt) treated like they treated like the (Rev), or maybe just released at different times? I would normally just go with the original but if the alts have any worthwhile differences then I would like to keep them all. There are a good amount of them so I would hate to keep em all for no reason. Thanks in advance for any help with this and love ya!!
