In the original code all values are signed integers, so m_dynindex would
overflow and become negative, then the modulus of a negative value by a
positive one would generate a negative result and finally the next array
read would make the program crash.
Also the maximum value plus one of m_dynindex is not generally a
multiple of m_dynamic and this would cause a jump in the values of
liveindex.
- Remove the hotspot read tracker. This was never robustly implemented, but changes to the memory system made it much less useful, and the "speedup opportunities" which it aimed to determine are not very important from a current emulation standpoint.
- Remove the CURSP/GENSP state symbol and the generic sp() getter. Stacking semantics vary too much between CPU architectures for this to be of much use. (A "SP" symbol has been added to a few CPU cores whose stack pointers were otherwise not being registered.)
- Remove the cached pointer to device_state_interface and the state() fast accessor from device_t. Most users of device_state_interface either already had a pointer to the specific CPU device type or needed to check first for the presence of the interface.
- Change the PC memory write tracker to use pcbase(), which works even when the instruction callback is masked out, instead of peeking at the PC history index.
- Remove some obsolete watchpoint-related definitions from machine.h.
- Improved support for Super HiK 300-in-1 related multicarts. Fixes graphics in some games and gets a 9999-in-1 working.
- Added missing board support for 500-in-1 and related multicarts. These are correctly assigned to mapper 217 in the .nes loader.

- Perform AMB before COM (tx0_64kw)

- Only call the debugger hook once per instruction cycle
* Fixed friended derived classes.
* Added "a2" prefix to device short names uesd for crude namespacing.
* Added the prefix header explicitly so it will build without PCH.
* Fixed bizarre mixed space and tab indenting.
* pengseal: Fixed company and title screen graphics.
* dongdong: Added device for this unique board (should have been marked not working.)
* mc_sg20: Fixed graphics fixed in all games, no longer randomly resets to Bomberman mid-game in Hogan's Alley.
* mc_190: Refactored code - this is the same as mc_sg20 with a mirroring bit.
* mc_1994: Corrected banking code - all games work now.
* mc_4ck1: Runs now, although Contra has some incorrect tiling issues; added jumper setting.
* mc_6m23: Fixed graphics in all games (light gun still not working due to non-bus issues).
* magicdrg: Fixed background tiling.
