Some programs you'll have to use

If you want to install games patched by Harry, you'll need the Patcher. Version 1.04, directly comes from Harry. If you want to install some games patched by Harry, Bert, Girv, Mr Larmer or Gore Design, you'll need WHDLoad. I don't use WHDLoad because I developped my system in parallel, but WHDLoad is cool.
If you want to use my new loaders, then you'll have to get JOTDStartup, a WHDLoad equivalent, but more powerful :)

Look inside the games

If you want to patch/write your HD installers yourself, those pieces of software can help you (all are freely distributable freeware/shareware):

Assemble your loaders
