I'm working on a mod for a Data East game, and would like to know if anyone has a Williams (or DE) symbol table they are willing to share so I can disassemble the code more easily. What I have so far is: cpu 6802 org 0x4000 vector 0x2400 pia_solenoid_PRA vector 0x2401 pia_solenoid_CRA vector 0x2402 pia_solenoid_PRB vector 0x2403 pia_solenoid_CRA vector 0xFFF8 irq_vector int_entry vector 0xFFFA swi_vector swi_entry vector 0xFFFC nmi_vector nmi_entry vector 0xFFFE res_vector reset However that is just the start...obviously more work is needed. Thanks!
