# Cemu detailed changelog for 1.7.3d# Patreon release date: 2017-03-10# Public release date: 2017-03-17# New in public release:general: New game profiles# New in 1.7.3d:GX2: 1.7.3 accidentally broke compatibility with pre-1.7.3 cached shaders. This hotfix restores backward compatibility.Also made some adjustments to guarantee this doesn't happen again in the future.# New in 1.7.3b/c:JIT: Fixed potential softlock for busy-wait loops which use the LWARX/STWCX instructionsGX2: Fixed incorrect shader source generated for streamout write exports when the shader is optimized for float-only# New in 1.7.3:JIT: LWARX instruction now consumes multiple virtual cycles. This speeds up busy wait loops.general: Screensaver/Standby should no longer come up while a game is playing in Cemucoreinit: Added API LCDisableDMA(), LCGetAllocatableSize(), MPResetTaskQ(), OSPeekMessage(), OSEnableHomeButtonMenu()coreinit: Fixed bug in LCEnableDMA()coreinit/FS: FSOpenFile() is no longer blocking CPU executioncoreinit/FS: Added internal support for priority-based path overloadingcoreinit/FS: Cemu will load patched game files automatically from mlc01/usr/title/../../ACP: Added ACP library. New API: ACPCheckApplicationDeviceEmulation()AOC: Added proper support for AOC library. Addon content (DLC) is automatically loaded from mlc01/usr/title/../../aoc/ or mlc01/usr/title/../../<aoc_titleId>/AX: Fixed internal ADPCM playback offset calculation for addresses above 0x80000000Input: Fixed bug that caused non-keyboard buttons to be detected as keyboard inputGX2: Improved implementation for GX2CalcTVSize() and GX2CalcDRCSize()GX2: Shader code optimizations. Up to 40% faster compile time for float-only shaders (measured on NVIDIA)GX2: Added support for shader OP3 CNDGT_INT instructionGX2: Added support for vertex format FMT_16_16_16_16, nfa=0, signed=0GX2: Fixed software streamout reading format 32_32_32_FLOAT incorrectlyGX2: Added support for vertex shader gl_PointSize exportGX2: Fixed a race condition in which the GPU7 command processor could run ahead of the current write pointer before GX2Init() was calledGX2: Fixed sampler min and mag filter value being read from wrong register bitsGX2: Added support for streamout binding the same buffer as input and output
