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

e7b8bda771 Implement clock-dividing for FPUs on clock-multiplied 386s
This is done by making it so that if the FPU is not at least a 487SX, the clock cycles are multiplied by the CPU multiplier.

cfc626f111 Change to logging - when logging is disabled, the logging functions are now #define'd to nothing, so the compiler ignores the lines that call them completely, seems to slightly speed up the emulator; note that the logging in vid_table.c has not been changed yet, because this file on my local tree currently contains other WIP changes. 2018-10-19 00:39:32 +02:00
