If you wanna play without CD here are the solution
(hope you are not a beginner...)
You need edit 2 files: SANITY.EXE and SANITY.REZ.

Sanity.exe: use unsafedisc and change offset $11e0 (4011e0)
A0 to C3 (it will back a return from the GETDRIVETYPE sub).

Sanity.rez: change offset $3be92d2 hex 6A to $C3
(search bytes 6A FF 68 98 74 0A 10 64 A1 00
and hex 6A the start of the GETDRIVETYPE sub)

That's all...
