Hidden Credits

A full set of credits are present in the game, but they were dummied out before the game's release.

There are two methods to re-enable these credits. Put the following cheat(s) in MAME's crossbow.xml cheat file:

<cheat desc="Attract Mode Credits Fix 1"> <script state="run"> <action>maincpu.mw@8AF0=124F</action> </script> </cheat>	<cheat desc="Attract Mode Credits Fix 2"> <script state="run"> <action>maincpu.mw@81CA=8AF1</action> </script> </cheat>
This fixes the credits subroutine by changing the RET opcode (which makes the rest of the subroutine moot) to an NOP. While this will display the credits, a bug in the game causes the credits to be displayed every time the screen fades out in attract mode.	This code simply replaces the instructions screen with the credits screen.

Developer Message

This message is in the sound CPU at E3B0:

DMA.A69
COPYRIGHT (C) 1983
EXIDY INC.
MARK VON STRIVER
LA PLUME DE MA TANTE EST SUR LE BUREAU

The last sentence is derived from a useless but ubiquitous phrase used to demonstrate grammatically correct French. The full sentence would be "La plume de ma tante est sur le bureau de mon oncle".
