Cheats

SGB Correctly Scans GB Address Space
- BIOS mode gets the same GB-address-space cheat handling bios-less mode already had: the cheat search scans GB WRAM/SRAM/HRAM, results display as GB bus addresses,
- GB GameShark / Game Genie codes parse, and apply/restore route through the GB core. Previously BIOS mode scanned the SGB BIOS''s own SNES WRAM (useless for game cheats) and saved SNES-space cheats into the same per-game .cht file that bios-less mode interprets as GB cheats.
- Load order is safe: both BIOS-mode load paths re-run S9xInitCheatData() after the flag is set, with the GB cart already loaded.
Standard cheat/code formats
- Raw codes display and save as xxxxxx:bb; conditionals as addr?compare:value (e.g. 198a?e0:f0) — the format cheat sites, decoders, and other emulators use. All legacy forms (=, addr:cmp?val, /) still parse, so old .cht files keep working.
- GB cheats print without SNES-style %06x zero padding, and GB bank-0 ROM patches no longer leak the internal 0x01000000 ROM-flag into the displayed address; the bare address parses back to the identical patch.
- A conditional colon code previously matched the plain pattern and silently dropped its compare byte; the pattern order now handles it.
- Set Value takes the value as whatever follows the last :/= of the displayed entry.
- The Cheat Entry and Editor dialog gains a minimize box.
ROM revision mismatch warning
- New checks for GB Game Genie code, verify byte against the loaded ROM (bank-0 sites directly, banked codes as any-bank match). The Win32 editor warns on Add/Update when a code was authored for a different revision and would silently no-op.

Rewind

Never-ending rewind fixed.
Paused reverse frame advance added**
StateManager::init() kept a stale bottom_ptr across re-inits, so once the ring had wrapped in an earlier epoch, holding rewind drained real history and then ran forever over stale entries.
Normalizes pop() returns (negative error codes were truthy for Settings.Rewinding).
fixes for held-hotkey chords sticking when modifier and key release in the "wrong" order, and makes the rewind key while paused step exactly one frame back per tap (content-frame tags in the ring, hidden replay of the gap, re-push so consecutive taps stay O(1)).

Event-cart savestate loadng

Remap the game window before PC base on unfreeze
- Non-fast unfreeze hard-resets first, which maps the PF94/CC92 menu back into the game window; S9xSetPCBase then resolved the restored PC against the menu mapping and the CPU derailed within frames on any in-game savestate load or rewind pop.
- The PF9 block is now restored and the window remapped before S9xSetPCBase, matching the SFC-Box supervisor restore ordering. Also rebases the session timer on load to avoid an instant time-over from unsigned wraparound.

SGB Audio

Core timing
- Slaving clock, scanline-wrap loss, and DRC seed fixes for the BIOS-mode pacing chain.
- ProcessSound() recreates the sync-to-sound throttle in BIOS mode and adds drain waits, fixing runaway speed and crackle.

Audio Waveform

Logic Pro - style per-track L/R level meters with peak hold (953d46bc), sqrt zoom + 20 Hz refresh defaults.
Logic-style record-arm [R] per track: unbounded-length WAV capture at source rate via cursor-based ring taps, Save-As on stop.
Footer rate selectbox + stats-for-nerds toggle for per-row diagnostics (aa39080c), vertical zoom selectbox,
Reset-on-close checkbox and solo-aware Channels menu.
Cheaper waveform paint and continuous envelope trace.
