The generic-shape tools (findWriter, getCPUState, searchValue, readCartRom,
classifyRegion, cheats, disassembly) work on all 14; deep per-platform
inspectors are detailed for 12 (PCE/MSX have generic shapes only so far).
gameCheats DB coverage 13/14 (all but C64), makeCheat/disassembleProject
updated to 14/13. getAudioState = 12 sound-chip systems.
