To use RMB under Windows 95 is easy. The only problem is to install 
RMB to run in the correct way. To do this you should edit
the filetypes in the following way:

(I have a danish version of Win95, so I'm just guessing what
 the menus are called in English...)

1. Open any folder, and choose the "show" menu.
   In this menu you select "settings", and a new
   settings window should open.

2. Now choose "filetypes".

3. If you have already registered the WAD filetype, you should
   select it in the list, and choose "edit". Then jump to
   step 5.

4. If you haven't registered WADs as a filetype, you should
   create it by selecting "new type". Write 'WAD file' under 
   "Description" and specify 'WAD' as the extension.

5. Now click "New" to add RMB as an action.
   Write "RMB" as the name of the action, and choose "browse"
   and go to the RMB directory and select rmb.exe. Now
   Choose "OK" to accept the new action.

6. You might want to add inspect as an action just like RMB,
   in which case you just do exactly as in step 5, only with
   a different name. ('inspect' instead of 'RMB' and select 
   inspect.exe instead of RMB.exe)

7. Many other WAD tools can be added just like in step 5, but
   in some cases you have to write batch files to start the tools
   under win95. This is the case if the tool needs to be started
   inside the home directory, or the tool needs another command
   line than just: TOOL <wad file>

   For instance this batch file will start DEU (5.21) on a wad:
	d:
	cd \doom\deu
	deu -file %1
   (If deu is installed in the D:\DOOM\DEU directory of course)

8. When you are through adding tools, just close all windows,
   and find a wad to test the new tools on. Simply click
   on the WAD by using the right mousebutton, and select
   the tool you need from the pop-up menu.
