1. ## [Release] Rubik's Cube (Update)

The Rubik's Cube is a 3D mechanical puzzle invented in Ernő Rubik. In a classic Rubik's Cube, each of the six faces is covered by 9 stickers, among six solid colors (traditionally white, red, blue, orange, green, and yellow). A pivot mechanism enables each face to turn independently, thus mixing up the colors. For the puzzle to be solved, each face must be a solid color.

The controls in this homebrew are designed to easily perform "Move notation" algorithms.

PSP Rubik's Cube v1.3 by EXTER.

Controls:
R: Front move.
Sqaure: Left move.
Circle: Right move.
Triangle: Up move.
Cross: Down move.
Left: Rotate cube left.
Right: Rotate cube right.
Up: Rotate cube up.
Down: Rotate cube down.
L + Up: Back Move.
L + Down: Back Inverted Move.
L + Left: Rotate cube clockwise.
L + Right: Rotate cube counter-clockwise.
L + R: Front Inverted move.
L + Sqaure: Left Inverted move.
L + Circle: Right Inverted move.
L + Triangle: Up Inverted move.
L + X: Down Inverted move.
Select: Undo move.

Hold Start for 3 seconds to scramble the cube (resets the move counter).

Hold L + Start for 3 seconds to solve the cube (resets the move counter).

Use the analog stick to peek at the sides of the cube.

Notes:
The cube state and move count are automatically saved on exit, then loaded when the game is run.

Tested on 5.00 M33-6, but it should work on any homebrew-enabled firmware.
Version 1.3 Update:

Changes:
Version 1.3:
Back and Back Inverted moves.
Cube solve and scramble animations.
Move counter at the top right of the screen.
Session saving.

2. Hmm.. a Rubik's Cube game :)

Cool though.

Screens:

Thanks, EXTER

3. Wow, that looks kinda cool. Downloading now. Thanks EXTER and thanks tinmanx for the screenies

4. As a speedcuber this is actually a great program and the controls are among the best set-up for speedsolving a cube on the PSP. I just have a few problems. First of all, there is no timer which I would really appreciate. Second, the angle that we see the cube from is fairly annoying to use. It would be better if you set the angle just above the cube as in Ryan Heise's cube simulator: http://www.ryanheise.com/cube/speed.html Also, if you are looking to emulate all the standard cube notation moves(R, L, U, D, F, B) you should add a B move key somewhere. Otherwise, you have a pretty cool program here that does not try to over think the controls and simulates how you turn a real-life cube while speedcubing very well.

5. Version 1.3 Update:

Changes:
Version 1.3:
Back and Back Inverted moves.
Cube solve and scramble animations.
Move counter at the top right of the screen.
Session saving.
Download in the attachment on the original post.

6. Awesome update and great inclusion of B and B' moves. There is still the problem, however, of the lack of a good view angle. When you solve a cube in real-life you are always looking down at the cube which gives you the view of two sides - the upper and front faces. The angle that the program uses, however, sets the cube as if you are holding it up to eye level which allows you only to see the front face. The advantage of a higher angle(which would also allow you to see all the cube moves whether you do a front, right, left, back, up, or down face turn) would really make this a great program as it already excels in simulating a physical cube very well. Keep up the great work, though. I really am enjoying this cube better then most others despite its limitations in terms of view angle.
