Samurai Western

As you level up, points get harder to earn. If you want a fast way to increase your character's stats and level, you should have a fairly powerful (L13+) Hyakki Yako weapon (high stance) and the Cowboy Accessories Set (or any accessories that give you a large amount of MP). Enter Stage 14 Wilderness on Normal or Hard difficulty and turn on the Custom Rules for Constant Master Mode, No Falling, No Grabbing, and Under Time. Go through that stage and kill all the enemies as usual. At the end, you should jump up quite a few levels. If Gojiro is already at Level 99, playing through Stage 14 with those four custom rules active will pretty much top off an entire level each play. (Note: you will not be able to increase the performance of accessories or weapons due to Master Mode being constantly on).

Take the game's cover art out from the case and turn it over to see an alternate version.

While playing on any level, pause the game, and on the pause screen, hold down applicable L and R buttons and fairly quickly tap the code on the D-pad with those buttons depressed. First, hold down the L1 or L2 input, then, while still holding it down, add the R1 or R2. If you just hit the two buttons at once and hold them down, the codes don't always seem to be read properly.

A sound effect will notify you that when you un-pause the game, it will be with the desired effect. If there is no sound, release the buttons and try again with the game still paused.

These codes work for both the North American and Japanese releases of this game.
