  History
-----------------------------------------------------------------------------

070428 Initial release




 Overview
-----------------------------------------------------------------------------

This is a translation patch for the Mega Drive game "Dynamite Headdy".
It sports a variable-width font engine with kerning support and, as usual,
it is a "dual-language" patch, meaning that it supports both Japanese and
English, depending on the country code of your machine.




 Applying the Patch
-----------------------------------------------------------------------------

Hopefully included with this document is a patch file in the IPS format.
You can use any program that supports that file format to apply this
translation patch to your ROM file.

Alternatively, you can use the program from my website to apply the patch,
but make sure that you have the latest version or it won't work.  The program
will check the ROM file (de-interleaving it if necessary) and will give
you an error message if something went wrong.  A normal IPS program cannot
do this as it has no idea what it is patching.  The program has not been
extensively tested, so if you have problems (or simply don't trust a foreign
executable) you always have the option of using a different program.

Please note that you are morally obligated to own an original copy of this
game in order to use the ROM file.  However, I am sceptical of those who
claim that it is illegal to do otherwise.




 Playing the Game
-----------------------------------------------------------------------------

Once you've patched the ROM file, simply load it up in your favorite
Genesis / Mega Drive emulator, console copier, or flash cartridge.

The game will detect the country code of your machine (real or emulated) and
then switch to English or Japanese mode accordingly.  This permits you to play
the game in the original Japanese, if you so desire.




 Q & A
-----------------------------------------------------------------------------

Q: This patch doesn't work!  What do I do?

A: Make sure that your ROM file is not in an interleaved format.  It's also
   possible that there is more than one version of the game, or that your
   copy is corrupt.  If you have problems, try using the program that I wrote
   to apply the patch; it checks for the above issues.  It is available on my
   website.

   If you are using a different patching program, please make sure that the
   ROM file you are patching is the official Japanese version, not the
   English or beta version, and that it has not been modified or corrupted.


Q: It doesn't work with my copier / flash cartridge!  Why not?

   This was tested on a real Genesis so you shouldn't have any problems in
   that respect.  The most likely reason is that something went wrong during
   the patching process.  See the previous question and try it in an emulator
   to see if that works.


Q: Is your patcher program safe?

A: No.  Anyone could replace it with a trojan and rewrite this readme to
   make it seem safe.  That's one reason why I don't include it with the
   patch itself.  It's up to you to decide which program to use to apply
   the patch, but unless you wrote the program yourself there's always
   some risk involved.


Q: Why is the text in Japanese?!?

A: This is a dual-language translation patch.  If it detects that it is
   running on a Japanese system, it will use the original game script.
   If you are using an emulator, make sure the country code is set to USA.


Q: Why does my emulator/tool say the checksum is bad?

A: This game uses a non-standard method to calculate the checksum.
   If the checksum really is bad, you'll get the "red screen of death".


Q: Were there any textual differences in the beta version of this game?

A: No, except that the beta script was shorter.
