795a6017d2 PIC rewrite, proper SMRAM API, complete SiS 471 rewrite and addition of 40x, 460, and 461, changes to mem.c/h, disabled Voodoo memory dumping on exit, bumped SDL Hardware scale quality to 2, bumped IDE/ATAPI drives to ATA-6, finally bumped emulator version to 3.0, redid the bus type ID's to allow for planned ATAPI hard disks, made SST flash set its high mappings to the correct address if the CPU is 16-bit, and added the SiS 401 AMI 486 Clone, AOpen Vi15G, and the Soyo 4SA2 (486 with SiS 496/497 that can boot from CD-ROM), assorted 286+ protected mode fixes (for slightly more accuracy), and fixes to 808x emulation (MS Word 1.0 and 1.10 for DOS now work correctly from floppy). 2020-10-14 23:15:01 +02:00

0b4b2b4d2f A number of recompiler fixes and put some of the timer/cycle-related changes behind #ifdef's as they are no longer used but someone may want to still try them out. 2020-07-15 18:30:27 +02:00

ec74ffb6a5 Old recompiler improvements: limited in-block IRQ checking to floppy IRQ's only, rewrote the GPF handlers in ASM, and changed the recompiled INC and DEC instructions to actually use INC and DEC on host. Also removed the keyboard_at.c timer hack. 2020-07-15 05:03:19 +02:00
