Fix stack corruption in CALL/RET/RST and add STOP instruction support
...
Major fixes:
- CALL, RET, RST, and their conditional variants now properly check
stack_in_ram before accessing memory via A3. Previously they assumed
A3 was always a valid native pointer, causing memory corruption when
in slow mode (A3 held raw GB SP value like 0xFFFE).
- Fixed initial SP setup to use fast mode with A3 pointing to actual
HRAM memory instead of holding the raw GB SP value.
- STOP instruction now calls runtime handler to check for CGB speed
switch instead of immediately halting. Enables double-speed mode.
- HDMA cancellation: writing to HDMA5 with bit 7=0 while HDMA is active
now cancels the transfer (fixes Pokemon Crystal).
Safety improvements:
- Added src_ptr bounds check to prevent m68k_offsets array overflow
- Added PC validation to reject execution in VRAM/external RAM
- Added PC history ring buffer for crash debugging
Tested: Klax, Link's Awakening DX, Wario Land 3 now boot successfully.
