Bart Trzynadlowski 121f81c742 68K now uses run-time hooks for IRQ and instruction hook callbacks 2022-11-02 18:46:08 -07:00
toxieainc cb9d73c9d0 port some (simple) changes from MAME/MESS 2022-08-09 20:37:42 -07:00
toxieainc 4961951a89 fix a real error (m68kdasm) and some harmless performance warnings and use modern headers 2022-07-11 18:10:41 +02:00
Bart Trzynadlowski 6bf4244207 Converted line endings from DOS to UNIX format. 2015-06-13 02:56:26 +00:00
Nik Henson 5a0f038171 Changes to allow debugging of Musashi 68K core:
- added methods to attach/debug debugger.
- added instruction hook & callback to m68kconf.h and added hooks into CMusashi68KDebug to allow debugger to control execution.
- added methods to allow reading/writing of 68K registers (for all registers and for a given context, rather than just current one).

Bart Trzynadlowski 2f5bf43bda Updated copyright information and added headers to all remaining files except debugger. 2011-09-14 19:08:43 +00:00
Bart Trzynadlowski e6f19c40ef Fixed 68K save state problem: pending interrupts were not being saved, sometimes causing the DSB2 to take an invalid interrupt (from the sound board 68K) after loading a save state. Save states are no longer compatible with previous revision. 2011-09-12 18:14:49 +00:00
Bart Trzynadlowski 6c5b4293eb Musashi context is now cleared in M68KCtx constructor. The internal Musashi context is zeroed out initially but the dynamically allocated external contexts would sometimes be filled with garbage, which would trigger interrupts at the very first instruction after reset, making the 68K go off into the weeds. This fixes a nasty randomly-occurring bug I was seeing. 2011-08-14 23:59:01 +00:00
Bart Trzynadlowski 91c9b9869b R. Belmont's changes to compile under MacOS and Linux. 2011-08-10 04:24:15 +00:00
Bart Trzynadlowski ddd6fa92ef - Improved 68K interface. Now supports context switching.
- CSoundBoard is not derived from CBus.
- Optimized sound board memory handlers (now using switch statements).
- Added DSB emulation (based on R. Belmont's M1 source code).
- Improved ROM loading: only unique ROMs (those not shared amongst games) are used to identify games. The ROM loader will no longer get confused as easily.
- General cleanup here and there, removed unused Render.h file.

Bart Trzynadlowski c73cb830dc - Added the Musashi 68K emulator by Karl Stenerud. Obtained Karl's explicit permission to relicense the code under GPL.
- Added a 68K interface, CPU/68K/M68K.*.
- Moved Turbo68K source files to CPU/68K/Turbo68K. It is no longer used but is being retained in the source tree for now. The LSR instruction has not been fixed in this update.
- Changed sound board code to use the new 68K interface (and hence, Musashi).
- Changed version string from 0.2-WIP to 0.2a-WIP. This is still an alpha version.
- Above changes have broken the 68K debugger.
