About

PCE / PCE CD

When editing or debugging PCE code, read and follow Core/Src/porting/pce/CLAUDE.md in full.

Quick pointers:

Linux harness: cd linux && make -f Makefile.pce (play) or make -f Makefile.pce debug (trace/self-tests).
Savestate padded layout: SVARs at byte 13, then pad to 76 KB, then CD RAM — never fseek(76KB) before SVARs (Valis II freeze).
ADPCM: pce_adpcm_sync() on status polls ($1800, $1803, $180A, $180B, $180C) + per frame; not every $180x read.
Arcade Card: PCE_ENABLE_ARCADE_CARD; phys reads need (MMR[page]<<13)|(addr&0x1FFF).
Low CD volume: grep FADER pcecd_diag.txt — stuck fader after $180F fade without CANCEL.
