- Fix Type 1 multifunction: AMF=bits17-13, DD=bits19-18, PD=bits21-20 (was off by one bit, causing wrong MAC decode on real firmware) - Add FIR filter ROM (fir.bin): 52 instructions, assembled from AD example - Add IIR biquad ROM (iir.bin): 28 instructions, assembled from AD example - Add open21xx-compatible source files (build/fir.dsp, build/iir.dsp) - Both ROMs disassemble correctly showing expected DSP patterns: MAC+dual-read kernels, DO UNTIL loops, ASHIFT scaling, RTS(DB) - Full regression: isa_test.bin unchanged
