Robin Hood: Prince of Thieves

Robin Hood: Prince of Thieves is a Zelda-like action/adventure game presumably based on a movie.

Extra 4 Lives
At the title screen, press А, А, В, А, В. A sound will confirm that the code has been entered correctly.

Extra 6 Lives
Surprisingly, there are actually two "lives" cheats. At the title screen, press А, А, А, А, В, В, В, А. Again, a sound will confirm that the code has been entered correctly.

Secret Passwords
It's fairly well-known, but this game contains a hidden password mode, which allows you to skip ahead to any segment of the game, including straight to the ending. At the title screen, press A (x8), B (x8). You'll be given all the items you strictly need to succeed, but not everything you otherwise would have, such as certain weapons and armor.

Debug Menu
A powerful debug mode exists. Most interestingly, you can access it without hacking. At the title screen, press А (x8), В, А (x7), В, А (x6), В, А (x5), В, В, В, and once again, you'll know if you succeeded via a sound effect. During gameplay, you can toggle between the normal gameplay and the debug mode just pausing the game by pressing the Select button.

While in cheat mode, instead of the standard menu, after pressing Start, the cheat menu appears. This menu allows you to either fight any duel in the game, or warp to any location. Additionally, your HP will be always 100, rendering you invincible, and you can walk through walls and other obstacles.

Completely Unused
Unused items in video games are nothing new... but it's a rare case when they're actually mentioned in an official source! Many of these items were included in the manual, but were left out for whatever reason, leading many a player to fruitlessly search for them.


 * Short Sword - Not really a sword, but rather a stronger, heavier version of the Knife with the same icon. Attack: 6, Weight: 4.


 * Steel Sword - A standard sword which, like the Short Sword, is just an upgrade to the "Sword", and also uses the same icon. Attack: 10, Weight: 8.


 * Claymore - Presumably another sword-type weapon. "Presumably", because this weapon is basically one big glitch. It has no icon, and hacking it into the game causes the entire menu to flip out, as seen in the screenshot. You can equip the weapon and attack with it normally, but if you drop it, it cannot be picked back up, and may freeze the game. Attack: 12, Weight: 10.


 * [[Image:Rh-shield.png|It is indeed a shield.]] Shield - There were two shield-type items in the game, both mentioned in the manual, and both left unused. Noteworthy for having a unique icon.


 * [[Image:Rh-shield.png|How would these have worked, anyway?]] Locksley Shield - There's a Locksley Sword, Locksley Armor, and a Locksley Bow, so it stands to reason that there'd also be a Locksley Shield. Same icon as the other shield, and probably stronger somehow.


 * [[Image:Rh-ladder.png|Not a ladder.]] Ladder - This item has no use, and its icon is just an odd palette swap of the Rope. Presumably, it would have had a similar effect. Unlike the other items listed here, this wasn't mentioned in the manual, so it may have been cut much earlier in development.

Partially Unused
A few miscellaneous items/objects can also be hacked into the inventory, something which never occurs normally.


 * Quiver - Found here and there throughout the game, and dropped by some defeated enemies, these add a few arrows to the "Arrow" counter on the menu, and are never normally seen in the inventory.


 * Gold Coin - Gives you 1 gold piece. Found laying around or dropped by enemies, another item that's just added to a counter, and not the inventory.


 * Bag of Gold - Same deal as the Gold Coin, except worth more, obviously. If hacked in, these items can be dropped and picked back up, and they'll function normally. Both the quiver and gold items weigh 1 "unit".


 * Locked Chest - Not an item, just a treasure chest, which you need a Chest Key to open. These can't be picked up, and aren't even technically items, but can be hacked into the inventory nonetheless. It's a bad idea to do so, however, as it weighs a whopping 229 "units", rendering you unable to pick up anything else until it's discarded. If you do discard it, it simply vanishes.


 * Empty Chest - Same as above, basically. Just what's left of the chest after opening it. It's not as ridiculously heavy as the locked version (185 "units"), but still not worth hacking in. Like the Locked Chest, it disappears if dropped.

Unused Music
The NSF file contains three songs not used at any point in the game:

Unused Song


Track 4 on the NSF. A rather heroic song that sounds like it might have worked for the opening/title or ending.

Unused Fanfare 1


Track 18 on the NSF is a short, victorious-sounding fanfare.

Unused Fanfare 2


Track 25 on the NSF is another short, victorious-sounding fanfare, although different from the previous one.
