First thing.....
Your either behind in the "game" or you meant to say the Messiah 2....
The original Messiah has been replaced by the updated Messiah 2...
They are not expensive and not hard to find... Just be sure that whoever you get it from is selling "GENUINE" Messiah 2's....
There are ALOT of clones running around.....
Dont even bother with the Magic 3.1..... Its an OK chip, but spend a few extra bucks and get a Messiah 2.... (Unless you want all the BS features that the DMS 3 has...Or you can go a little bit cheaper and get an Apple 2) I think its called the Apple 2....
Bighap is the MAN when it comes to Apple chips so I'm sure he will correct me if I'm wrong....
As far as booting.... The Messiah 2 will boot EVERYTHING..... For that matter, even my "original" Messiah will still boot ALL games released to date....
As far as installers.... Where are you located at....?
Dont bother with clip kits.... They have a tendency to come loose and cause problems.... True.. It does reduce the number of wires that have to soldered.... BUT if you or whoever can solder the wires that a clip kit requires, you or whoever can solder the wires that the chip itself requires...
Hope this helps...
