Changelog

BETA 4

• Re-factored the rendering pipeline. This has improved speed and gotten rid of the shearing effects on the right of the screen, as well as several graphical glitches.
• Game too dark? Added a gamma correction setting to the OpenTyrian menu.
• Some of the keyboard textures have changed. If upgrading from a previous version, you will need to re-copy the 'PSP' sub-folder into your Tyrian folder.

BETA 3

• Completely re-factored the virtual keyboard. It is now Tyrian-themed and sits beside the main screen when active.
• The virtual keyboard will auto-activate when a text-entry field is active, and close once text is entered.
• If you are upgrading from a previous version, you will need to copy the 'PSP' sub-folder into your Tyrian folder.

BETA 2

BETA 1

• Major sound quality improvements.
• Replaced generic button names with PSP button names in Joystick Options.
