// Helper Macros for Reading Emu Configurations.

// ------------ CPU / Recompiler Options ---------------

// (ARM64 Phase 7.8) microVU0/1 are now ported, so REC_VU1/THREAD_VU1 track the config
// on both architectures — the old ARM64 hardcoded-false stub would make GetGSPacketSize
// take its `!REC_VU1` path and return the XGKICK packet size with the bit31 EOP flag set,
// which mVU_XGKICK_ then mis-reads as a multi-GB transfer (memcpy crash on the first kick).

//------------ SPECIAL GAME FIXES!!! ---------------
#define CHECK_VUADDSUBHACK (EmuConfig.Gamefixes.VuAddSubHack) // Special Fix for Tri-ace games, they use an encryption algorithm that requires VU addi opcode to be bit-accurate.
#define CHECK_XGKICKHACK (EmuConfig.Gamefixes.XgKickHack) // Special Fix for Erementar Gerad, adds more delay to VU XGkick instructions. Corrects the color of some graphics.
#define CHECK_EETIMINGHACK (EmuConfig.Gamefixes.EETimingHack) // Fix all scheduled events to happen in 1 cycle.
#define CHECK_INSTANTDMAHACK (EmuConfig.Gamefixes.InstantDMAHack) // Attempt to finish DMA's instantly, useful for games which rely on cache emulation.
#define CHECK_SKIPMPEGHACK (EmuConfig.Gamefixes.SkipMPEGHack) // Finds sceMpegIsEnd pattern to tell the game the mpeg is finished (Katamari and a lot of games need this)
#define CHECK_OPHFLAGHACK (EmuConfig.Gamefixes.OPHFlagHack) // Bleach Blade Battlers
#define CHECK_DMABUSYHACK (EmuConfig.Gamefixes.DMABusyHack) // Denies writes to the DMAC when it's busy. This is correct behaviour but bad timing can cause problems.
#define CHECK_VIFFIFOHACK (EmuConfig.Gamefixes.VIFFIFOHack) // Pretends to fill the non-existant VIF FIFO Buffer.
#define CHECK_VIF1STALLHACK (EmuConfig.Gamefixes.VIF1StallHack) // Like above, processes FIFO data before the stall is allowed (to make sure data goes over).
#define CHECK_GIFFIFOHACK (EmuConfig.Gamefixes.GIFFIFOHack) // Enabled the GIF FIFO (more correct but slower)
#define CHECK_VUOVERFLOWHACK (EmuConfig.Gamefixes.VUOverflowHack) // Special Fix for Superman Returns, they check for overflows on PS2 floats which we can't do without soft floats.
