KILLER
INSTINCT
1994 RARE LTD
SINGLE
BOOT ROM
REVISION 2.0.1
AGPL-3.0 OPEN SOURCE
A drop-in replacement for the stock U98 boot ROM. One image per board and game version, flashed once.
ANY IDE DRIVE
No drive-model check — CF, SD, DOM and SSD adapters all boot.
BOTH BOARD REVISIONS
KI-U96 A-19489 and KI2-U96 A-20351 — KI1 and KI2 each run on either board.
RUNTIME PATCHES
The game ROM is patched in memory at boot — nothing on disk is modified.
FAST BOOT
LZSS-compressed game image loads faster than the stock ROM path.
BOOT OPTIONS
Dipswitch-selectable boot sounds and pause-on-boot, plus a new boot chime.
MAME FRIENDLY
Fixes the no-sound-at-boot issue under emulation.
