New GREAT patches to Marathon 1.1

[Nobuhiko Yoshida]

A friend of mine, Nao, found some useful patches for Marathon 1.1, which
have great advantages to Marathon Cheater 2.5. Marathon Cheater can
change values of saved file ONLY. But by patching to Marathon application
itself, you can start with full weapons and ammos from any level by
option-command-clicking 'BEGIN NEW GAMES'. Without these patches you must
have difficulties in fighting in some levels, especially in Total
Carnage.
Now You don't have to rush to pattern buffer!

Unfortunately you need ResEdit or equivalent for 680x0 and disk editor
such
as SUM Tools for PowerMac.
