v1.5

I came back to fix a bug, but also added some more things.

Changes

• Added Music Mode setting. You can now play music in a fixed or shuffled order instead of looping a single song.

Bug Fixes

• Fixed mini grid breaking after using the "reveal cell" cheat.

Technical Improvements

• Updated SDL2 libraries on most systems.
• Limited save file writing when rapidly changing music track with L/R.
• [Gamecube, Wii] Upgraded to libogc2, which introduces a variety of improvements including save/load support for FlippyDrive (thanks @Extrems!).
• [PSP] Big performance boost from upgrading PSPDEV, resulting in a steady 60 FPS.

Enjoy!
