NeoGeo的特殊bios，好处不用我多说了吧...不明白的去精华区找相关教学。更新内容如下：
WHATS NEW IN VERSION 2.2
------------------------
Additions / Changes / Fixes
The splash screen will no longer show twice or more (on multislots) after the backup
memory is reset.
The memory card format option will no longer wipe the region stored in the memory card
on AES hardware.
The arcade protect setting can now have either the testmode button pressed or HardDIP 1
on (force test mode) to get access back to the button Codes on the splash screen.
Made visual improvements to the main memory card manager menu.
Cleaned up screens and messages in the memory card manager, test mode and hardware test.
Changed the Cheat database storage slightly. It now takes less space in the Bios which
is good thing as space was beginning to become quite tight.
Fixed the AES hardware test code (A+B+D) so it also works after the splash screen is drawn.
Fixed the hardware error message from disapeering on AES hardware as soon as the hardware
test button code (A+B+D) was released.
Fixes (game related)
Fixed the AES version of 'King of Fighters 2003' from crashing after exiting the ingame
menu (bug introduced in 2.1).
Fixed 'Andro Dunos' to start attract mode correctly on AES hardware.
