Jared Miller	fb8cbf7219	Implement op_verify and wire ZLexer into sread for Zork 1 ... op_verify now performs actual checksum validation against the header instead of raising NotImplemented. ZLexer is injected into ZCpu and sread tokenizes input into the parse buffer per the V3 spec.	2026-02-09 20:57:15 -05:00
Jared Miller	72dd047b7b	Port 5 complex opcodes to hybrid z-machine interpreter ... Implement op_sread (text input), op_save/restore (file I/O stubs), op_restart (exception-based reset), op_input_stream and op_sound_effect (no-op stubs). Add ZCpuRestart exception. All implementations follow TDD with comprehensive unit tests.	2026-02-09 20:44:22 -05:00
Jared Miller	c76ee337d3	Port 4 medium opcodes to hybrid z-machine interpreter ... Implements op_print_addr, op_print_num, op_ret, and op_show_status following TDD approach with tests first. Each opcode now properly decodes/prints text, handles signed numbers, returns from routines, or acts as a no-op as appropriate.	2026-02-09 20:44:22 -05:00
Jared Miller	1b9d84f41a	Port 10 object tree opcodes to hybrid z-machine interpreter ... Implemented 10 opcodes for object tree manipulation: get_sibling, test_attr, set_attr, clear_attr, jin, remove_obj, print_obj, get_prop_addr, get_next_prop, and get_prop_len. Added 6 supporting methods to ZObjectParser: set_attribute, clear_attribute, remove_object, get_property_data_address, get_next_property, and get_property_length. Fixed bug in insert_object where sibling chain walk never advanced the prev pointer, potentially causing infinite loops. Added 16 unit tests with MockObjectParser to verify CPU opcode behavior. All tests passing.	2026-02-09 20:44:21 -05:00
Jared Miller	dcc952d4c5	Port 12 trivial opcodes to hybrid z-machine interpreter	2026-02-09 20:44:21 -05:00
