SuperSnes9x 1.63.19

疾风之狼

1.63.19
New Mappers:
Three previously-unsupported cartridge mappers now load and run under SGB emulation. All three reuse existing MbcState fields, so the GB savestate layout is unchanged.

HuC1 (cart type $FD→ $FF) — Was a read-only stub, so ROM-bank-select writes were dropped and the game jumped into the wrong bank and locked up executing $FC filler.
Reimplemented as MBC1-with-infrared (ROM/RAM banking + IR register). Fixes Chousoku Spinner, Pokémon Trading Card Game.
HuC3 (cart type $FE) — Added the RTC command/response interface plus IR; boot gates on the RTC status command reading back ready. Fixes Robopon (Sun Version).
Bandai TAMA5 (cart type $FD) — The ROM was rejected at load entirely. Implemented its unusual two-register port ($A001 selects, $A000 carries one nibble), a 32-byte battery-backed EEPROM, the $0A ready handshake, and the TAMA6 RTC. Fixes Game de Hakken!! Tamagotchi - Osutchi to Mesutchi.
Game Boy / Super Game Boy fixes:
MBC5 keeps cart RAM readable when RAM-enable is off (2026-05-29). Some games run a trampoline out of SRAM; returning $FF while disabled hung them at boot. Fixes the Nettou King
of Fighters '97 SGB boot hang.
Optional frame-blend toggle — PR #87. Games that fake transparency by flickering two backgrounds (e.g. Chikyuu Kaihou Gun ZAS) can now blend each displayed frame 50/50 with the
previous one at the shared end-of-frame hook. New "Blend Game Boy Frames" checkbox in Display Settings.
Independent GB volume slider in SGB BIOS mode

1.63.18

This release fixes alot of games that uses Mappers as well as some games that are not playable on all emulators (like Messen)

GB PPU hardware correctness
STAT IRQ hardware quirks (LCD-off guard, LY=153 edge case) — fixes Zerd no Densetsu boot
DMG STAT-write quirk now only fires on newly-enabled source bits
Mode 3 sprite stall + WX latching — fixes One Piece dialog torn edges
BGP latch at mode 2→3 boundary — try-fix for split-scanline palette glitch
SCX-fine mode-3 penalty modeled (per-scanline raster timing)
Cart mappers support
Sachen MMC1 mapper + scrambled-logo detection (Sachen 4 in 1 4B-007 boot)

MMM01 multicart mapper added (Mani / Taito 4-in-1)
MMM01 sub-game SGB palette injection (no splash)
Cart MBC now resets on File → Reset (Sachen 4B-007 no-cartridge post-reset)
Cart SRAM defaults to $FF instead of $00 — fixes Initial D Gaiden text rendering
