b1c5cbaf47 Split the 286/386 interpreter away from the 486+ one (the 286/386 interpreter does not use the pccache's, readlookup's, and writelookup's as the emulated CPU's are too slow for them to be required, and also has more accurate FPU timings), also added a LPT status read function for future-proofing. 2023-08-08 19:39:52 +02:00

c10b05f35c Finally commented out the logging in the MOV TRx instructions. 2023-06-11 13:48:03 +02:00
OBattler
c76e8ff06c Replaced the codegen_ops_NULL table references with NULL pointers, as it has the same effect without requiring an extra table of opcodes, also made the new recompiler clear codegen_flags_changed after every interpreted instruction to prevent conditional jumps from occasionally taking the wrong turn (fixes CL-GD 54x6 driver glitches in 24bpp mode on Windows 98 SE), and added instruction length heuristics on fetching the instruction, fixes Jane's US Navy Fighters. 2023-06-09 14:55:13 +02:00

a9cc8cf898 Made softfloat work on the dynamic recompiler (not yet enabled in the Settings dialog, needs MMX and FXSAVE/FXRSTOR for softfloat first). 2023-05-07 00:24:57 +02:00
