Universe Bios v2.3 Released.
--------------------------------------------------------------------------------
I finally got around to releasing a New version of the Universe Bios. I was hoping to get this released sooner but it took longer than I had expected.
WHATS NEW IN VERSION 2.3
----------------------------
Additions / Changes
Hilighting 'Soft Reset' in the ingame menu will now give you new options when moving the 1up joystick left and right. New options are;
Main Memory Viewer
Video RAM Viewer
Menu Color Changer
The screen will now blank out if the ingame menu is left alone on its main menu page (after about 1 minute). Simply move or press any 1Up control to restore the screen. This new option helps prevent monitor burnin if you use the ingame menu to pause your games.
Removed the trackball cheat from 'The Irritating Maze', instead trackball support is always enabled unless the joystick cheat is used.
Fixes
Fixed a minor ingame menu color issue with 'Real Bout Fatal Fury'.
Fixed music offset so 'GhostLop' music can now be heard in the jukebox.
Fixed 'SVC Plus' bootlegs from not allowing character select when in console mode.
Cheats / CRC Database
Added crc info for 'Metal Slug 6 hack'.
Added crc info for the AES version of 'Metal Slug 4'.
Added crc info for 'King of Fighters 2002 Magic Plus (hack)'.
Added crc info for 'Crouching Tiger Hidden Dragon Super Plus (hack)'.
Added cheats to give 1000 credits in 'Jockey GP'.

Fixed the 'KOF 97' red energy cheat to the correct energy level.
Updated the 'KOF97' unlock bosscharacters cheat to also allow Orochi.
Updated the 'Fatal Fury 2' hidden character cheats, hopefully they wont't cause a crash now after winning a match. There will still be problems on the continue screen.
Added cheat to allow more than one projectile in 'KOF94' and 'KOF96' though it only works well if used with the action speed up cheat.
Added Cheat / CRC support for the following Korean releases.
