Their Finest Hour the Battle of Britain is a great game.

But having to twirl a silly code wheel really sucks! So if you are tired of

it just follow these instructions and suffer no more!

After you complete the patch, the "Press M to tune radio" will not bother you

again. Even if you "Tune" it with false info everything will still work.

You don't even have to bother tuning it if you don't want to.

Here's how to accomplish the patch.

By the way, smart people will make a copy of their original bob.exe and will


You will need Norton Utilities or Debug, Norton is easier.

If you are using Norton Utilities, Select Bob.exe and search for the following

byte pattern: 36 24 75 08 b8 01

That's using the "Hex" field in Norton's by the way.

When Norton finds it simply change the 75 08 to 90 90, write the data and quit.

You are finished!

If you are using debug do this:

from dos prompt:

ren bob.exe debug won't write out and exe file


- r debug responds with - you type r and enter

debug then displays a register dump, write down the value of cs

- s cs:0000 ffff 39 87 36 24 75 08 b8 01 00 8b e5 cs is the number you
wrote down earlier.

debug should respond with an address like this:


- u xxxx put the above value debug gave you in place of the xxxx

debug should display :

cs:xxxx CMP [BX+2436],AX
cs:yyyy JNZ 7762

- e yyyy you know the routine by now the yyyy is the value debug told yo

75.90 08.90 the 90's are what you type

- w

debug says "writing zzzz bytes"

- q

from the dos prompt:

ren bob.exe

Now run it and have fun!

A sleepy hacker

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read:
