Let me introduce all the different packages to you. First of all we have madBasic, which implements (as the name already implies) some basic stuff. All the other packages need madBasic. It contains some tool functions like message handling, compression, encryption and a lot of quite fast string functions.
The next package to mention is madDisAsm, a little disassembler, which can analyse binary code at any memory position and tell you several things about it.
One of my favorites is madExcept, which replaces Delphi's exception handling with a much more intelligent solution. With madExcept integrated into your projects, you will get detailed bug reports from your customers, which should directly help you to find and fix your bugs.
If you need to get into other processes, you should have a look at madRemote. With this package you can allocate memory in other processes, you can copy whole functions to other processes and you can create threads in other processes.
The package madKernel makes dealing with processes, threads and these kind of things very easy. There's a lot of undocumented stuff hidden in madKernel like converting handles to IDs or enumerating "secret" things.
Finally, one of the best available general purpose API hooking packages is here, namely madCodeHook. It combines the best available hooking methods with the easiest possible usage.
Have you ever tried sharing a folder in both win9x and winNT? The two OS families have totally different API sets. It's really a mess. With madSecurity it all gets much easier. You don't need to care about the operating system family anymore, madSecurity even emulates ACLs and ACEs in win9x to make your life easier.
Some nice things are contained in madShell, too. It encapsulates the most important shell COM objects, making them much easier to use.
