40 Winks: 40 Winks Crack

40 Winks was an unreleased game on the N64. Existing copies will display a message:
“This game can not be played on this system”

This is bupkis. The patch provided will allow you to start and play the game normally. As far as can be determined, the game is virtually complete.

If you don't wish to use the patch, the readme file contains the cheat code needed to get past the title message.

This crack bypasses the screen which displays:
"THIS GAME IS NOT DESIGNED TO BE PLAYED ON THIS SYSTEM"
Turns out there really isn't anything preventing you from playing the game after all ;*)

Two versions of the fix are provided here. You can either apply the patch to a rom image to permanently, or you can use GameShark cheat codes to hotfix the problem. Both do exactly the same thing.

+GameShark Version+
Enter this code into your cheat device:
8002E221 0000


+Patch Version+
Apply the patch provided to an +unbyteswapped+ 40 Winks rom (N4WX). The patch applies the fix and revises the checksum for you.

Technical:
The routine 8002E600 recieves a value V0 that denotes how to treat the current intro splash screen. Normal operation sets V0=1, allowing the menus to progress. However, fatal errors return V0=2, which fixes the screen permanently.
The patch simply forces the last test prior to the displayed message to always return true, causing it to branch with V0=1. Technically, it changes the test:
BEQL V0,V1,8002E600
to
BEQL R0,R0,8002E600

This occurs at 8002E220 in RDRAM, and 0x2EE21 in ROM.

If you suffer some terrible calamity, you can always attempt to write me. I don't have regular internet access, but I will try to return a message as soon as possible.
