DOWNLOAD the new firmware patch file

This firmware modification is based upon the original game code from Data East.

You will need:

• The original CPU ROM file version 1.12, which you can download from ipdb.org

• A tool that works for IPS formatted patch files; I recommend Lunar IPS which is available from fusoya.eludevisibility.org

• Finally you'll need my patch file, which is here

Instructions for creating your modified ROM image file

1. Extract the file lahcpua.112 from the ipdb zip file to your hard drive.

2. Extract the IPS patch file to your hard drive.

3. Run Lunar IPS, click Apply IPS Patch follow instructions.

4. Burn the resultant file to a new 27C512 EPROM.

Once you have your new ERPOM in hand follow the simple installation instructions above.
