Sat, 17 Sep 2022 15:38:40 -0700 Michael Pavone Implement MMAP_ONLY_ODD/EVEN in combination with MMAP_PTR_IDX. Fixes games that have SRAM when a system with TMSS is selected
Sat, 19 Mar 2022 15:50:45 -0700 Michael Pavone Fix some dynarec code invalidation issues
Fri, 18 Mar 2022 20:49:07 -0700 Michael Pavone Implement word RAM interleaving in 1M mode, now passes mcd-verificator word RAM tests
Thu, 17 Mar 2022 22:41:42 -0700 Michael Pavone Remove use of get_native_pointer in 68K instruction decoding in preparation for word RAM interleaving
Sun, 13 Feb 2022 22:52:52 -0800 Michael Pavone Fix handling of ram code flag offset calculation for ranges that are not an even multiple of the code flag page size
Sun, 30 Jan 2022 19:56:09 -0800 Michael Pavone Fix error in code write detection introduced from "wide" jcc change segacd
Tue, 18 Jan 2022 00:03:50 -0800 Michael Pavone Implement enough of Sega CD gate array and Sub CPU to pass Sik's Mode 1 test ROM segacd
Sun, 07 Mar 2021 22:43:51 -0800 Michael Pavone Fix bug in handling of MMAP_CODE regions smaller than 16KB
Sun, 31 Dec 2017 14:08:47 -0800 Michael Pavone Fix accidental add to RSP with SZ_D and SZ_PTR. Using SZ_D breakse when the stack is located outside of the 32-bit addressable range
Wed, 13 Sep 2017 21:06:25 -0700 Michael Pavone Preserve original address when retranslating instructions instead of switching to the lowest alias
Tue, 03 Jan 2017 21:18:42 -0800 Michael Pavone Fix RAM flag offset calculation to take into account the existence of non-writeable MMAP_CODE chunks
Thu, 22 Dec 2016 10:51:33 -0800 Michael Pavone More cleanup in preparation for SMS/Mark III support
Wed, 14 Dec 2016 23:26:12 -0800 Michael Pavone Fix a subtle bug in interrupt handling introduced with the move to a single cycle register in the Z80 core. Fixes regression in Puyo Puyo 2
Mon, 12 Dec 2016 19:21:22 -0800 Michael Pavone Fix to the fix of handling of self modifying code. Was ORing the base address with the wrong register before calling the modified code handler
Thu, 06 Oct 2016 22:25:12 -0700 Michael Pavone Made some optimizations to gen_mem_fun to keep the size of chunk handler sections within range of a single byte displacement

Thu, 06 Oct 2016 09:25:43 -0700 Michael Pavone Fix handling of MMAP_CODE chunks that also have MMAP_PTR_IDX set
Wed, 27 Jul 2016 22:46:22 -0700 Michael Pavone Change cycle tracking code for Z80 core to only use a single register. Store low 7 bits of R in a reg and increment it appropriately.
Tue, 26 Apr 2016 23:13:37 -0700 Michael Pavone Initial stab at implementing address error exceptions. Need to fill in the value of IR, undefined bits of last stack frame word and properly deal with address errors that occur during exception processing.
Wed, 25 Nov 2015 08:40:45 -0800 Michael Pavone Partially working change to do proper stack alignment rather than doing a lame alignment check when calling a C compile dfunction. 68K core seems okay, but Z80 is busted.
Sun, 22 Nov 2015 14:42:36 -0800 Michael Pavone Fix a bug in generating memory access functions when more than one MMAP_CODE region exists
Sun, 28 Jun 2015 13:30:17 -0700 Michael Pavone Fix self modifying code checks on platforms like OS X on which guest RAM ends up at an address unreachable with a 32-bit displacement
Sat, 27 Jun 2015 13:18:55 -0700 Michael Pavone Preserve scratch2 when using it as a temporary in memory read functions. This fixes a bunch of issues with the Z80 core and possibly some issues with the 68K core as well
