Urban Champion (JU): Pass 1 complete (CDL verified), Pass 2 complete - 519 labels renamed to semantic names via pass2.py apply - 10 zero-page semantic aliases added to locals.inc - Branch table at CB70-CBAC restructured per CDL (CB70-CB90=data, CB91-CBAC=code) - E07F-E09D region fixed (misaligned decode at E08D) - BYTE-IDENTICAL at PRG level verified Tools: - cdl_reclass.py: overrides now win over CDL conflicts - nesdis.py: fixed a: prefix parsing for JSR/JMP operands; IND mode emits no a: prefix - verify_pass1.py: all 17 top-level projects pass, no crashes

Pinball disassembly project.

you will disassemble a NES rom. I will provide you with the skeleton project as a tar.gz file renamed to txt. build the byte identical rom. once you have completed a first pass to identify the code vs the data blocks, stop and provide me with the code. The goal is a byte-identical disassembly. Identify code and data sections. After the first pass, take a second pass and replace the known labels. Pass a third time to better identify use of code and data tables naming more appropriately.

with code blocks that are generated, each method will have a local and global description, the parameters and the return value(s). for each instruction, include a comment at the end of the line with the offset followed by the actual bytes that are expected to be encoded. during building the byte exact source, include the remaining incbin line so we can cycle through builds quickly and efficently.

there are 2 files for symbols. symbols.inc which has NES specific values for APU, PPU, and controller. locals.inc has application specific values for zero page variables and forward references while decoding.
