I was originally going to put JRok's mod on this board but I wanted the high scores to survive test mode and to flip the inverted Universal screen.
For the screen flip patch you will need to patch 3 roms and the high score save patch is only one of the roms. You can apply just the flip patch or the high score patch or both patches, it is up to you.
The 2k ram that needs to be replaced is at E1 and should be replaced with an NV version such as DS1220, M48Z02, U63716DC etc.
The Flip screen is not selectable, I have left the dip switches alone. Cocktail mode should still work, just inverted. There are patches below for all four versions of the game that are in Mame. I have it working on an original board using the same version as docastle.zip.
To reset the high score table enable freeze, ground pin 6 of the edge connector (component side), when powering the board up.
As with all my High Score Patches, please post a reply or click thanks if you find this patch works for you.
