06998e4278 Corrected some 286/386 interpreter opcode table assignments in cpu/cpu.c. 2023-08-08 21:04:49 +02:00

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
