TomCh 839c493b67 Support IIe aux slot: 80-col(1KiB) card via generic read ptrs (#1341, PR #1391)
Better support the IIe's aux slot when it's empty or has the 80-col(1KiB) card.
- any h/w using this alternate CPU emulation, (ie. aux=empty or 80-col(1KiB)), then the 'mem' cache is completely bypassed.
Debugger: change all the direct 'mem' accesses to go via ReadByteFromMemory().
TestCPU6502: test the alt CPU emulation code too.

TomCh 16b2cf329e Support IIe aux slot: empty or with 80-col(1KiB) card (#1341, PR #1351)
Add new command line switch: -aux <empty|std80|ext80|rw3>
Add 6502/65C02 x normal/debugger alt read support for CPU emulation (#1353).
Fix bug in MemReadFloatingBus() reading from mem[] - no good, if MF_AUXREAD is set.
Support odd 80-col text video mode when aux slot is empty:
. add a new videoMode flag for VF_80COL_AUX_EMPTY.
Correctly support 80COL & DHIRES soft-switches when aux slot is empty or with std80 card.
Support VidHD's SHR with -aux <empty|std80>.
Save-state: support aux slot empty or with std80 card.

TomCh 577ffccf8f VidHD: Support SHR for Apple II/II+ models (#997, PR #1013)
. Support aux writes for II/II+ (6502 emulation, not 65C02)
. Extend VidHD save-state for II/II+ aux memory

TomCh 6e166dfff6 Support NSC for Apple II/II+ via F8-ROM (#827 PR #873) 2020-11-25 21:57:34 +00:00
TomCh ef913fe827 Removed 65d02 and used the regular 65c02/6502 headers instead (PR #825)
Removed 65d02.h and reconstructed this code using a combination of existing 6502.h/65c02.h and extra C Pre-Processor macros to include (or omit) the extra heatmap functionality.

We still end up with a normal 65c02 instance and also a debug 65c02 instance, but both will derive from the same 65c02.h file (+ same for the 6502 normal/debug instances).

Also:
. Added cpu_heatmap.inl for the built-in debugger's read/write operations.
. Support CpuRead/Write() from Z80 to hook the heatmap r/w.
