Hi All,

Thanks for reading, I have an old Game called Novastorm and back inthe day the only way to play the games with cheats was to modify the the execuatable via a hex editor.

I have confirmed that the modified execuatable is correctly modified and the game actually works with infinite lives and bombs on an old machine, but the cheats are not effective in dosbox.

Does anybody know why this should be the case, Im totally lost as to while it wouldnt work and the code would be execute in the same way.

Here is the procedure

Cheat Edit
NovaStorm add life method:
use any hex editor, edit NOVASTRM.CFG (in c:\), change the first byte to
any number you like. The first byte is the number of plane (life).
You can even make the file read-only.

another cheat edits:
Assume CD drive is E:
copy e:\novastrm.exe to c:\
edit NOVASTRM.EXE
unlimit life
search 66 FF 0D 98 2B 03 00 79 09
change EB 05 -- -- -- -- -- EB --

energy no reduce
66 29 05 95 2B 03 00 79 37
EB 05 -- -- -- -- -- EB --

bomb not reduce
FE 0D BF E8 02 00
EB 04 -- -- -- --
to run NOVASTRM, at E: type
c:\novastrm.exe

Definately confirmed it works on a hardware machine.

Anyobody found the same, has anyone got any ideas

Any repsonse would be much appreciated

thanks

Is this the exact same procedure you are using on your old machine, with drive E and everything?

It is highly unusual to run an exe file in C:\ instead of a subdirectory. It is also unusual to have a drive E without having a drive D.

Absolutely, The exe file executes perfectly and I actually check it with a hex editor to ensure the hex values were changed.
I find it so weird it does not not work, I assume the hex codes are just decrementing 0 rather than one, I would have thought if I had change the wrong code the execuatle would not have run and just crashed.

Very perplexed

That's not what I was asking about.
