1.2.68

sdl12-compat 1.2.68

What is this?

This is the release of version 1.2.68 of sdl12-compat. This is an official, stable release, and everyone is encouraged to upgrade. This release remains API and ABI compatible with previous releases of sdl12-compat (and, of course, with previous releases of classic SDL 1.2, as well).

TESTING IS STILL WELCOME FOR FUTURE RELEASES.

A list of known SDL 1.2 apps is here. Some tips on testing are in HOW_TO_TEST_GAMES.md. Please jump in and try things!

What works now?

Some apps and games that have started working since the last stable (1.2.64) release:

• Trine
• Mark of the Ninja
• Hyperspace Delivery Boy
• SDLmm C++ binding
• libsdl-perl

Significant changes

• Corrected SDL_SetPalette's return value. (#294)
• Fixes to headers to help compiling apps against sdl12-compat (#297, #299, #302)
• Sync dr_mp3 with upstream.
• Fixes to SDL_LoadWAV_RW (#310, #311)
• Reworked screen surface implementation to work more like real SDL-1.2 (#306)
• Fixed blank screens in Mark of the Ninja and Trine (#313, #316)
• Fixes to mouse tracking in relative mode when scaling (#318)
• Add quirk to clamp video bitdepth (#321), which fixes Hyperspace Delivery Boy (#317).

• SDL_GetWMInfo() no longer asserts if used on Wayland.
• SDL_WM_SetIcon() no longer crashes on NULL icons, to match SDL-1.2. (#208)

• Fixed rendering of 24-bit screen surfaces. (#183, #190, #199)
• Updated dr_mp3 with various MP3 decoding fixes, for virtual CD audio.
• Fixed building for ARM64 with Microsoft Visual C.
