One small detail you will have to remember is some games require a certain kickstart file to be preloaded etc, these are not readily available, you'll need to use all your powers of resourcing to acquire such addons ;-)

You probably just need to disable a certain cache (try typing cpu or similair and see what the syntax for disabling certain functions is), or look for a suitable degrader program on Aminet perhaps... If I remember rightly though a WHDLoad version of Syndicate does exist? This would obviously solve the timing problem.
