2010.06.15 This is basically the equivalent of the Unibios for the NeoGeo CD systems. The project was started on March 2010 and aims to achieve a comparable feature set although it has only been around for a fraction of the time. You may be violating copyright law in your region by downloading this BIOS without an original SNK CD system. Features include: - Software controlled region switching - Setting of the debug DIP and developer mode - Setting of the system type to “home” or “MVS” - Setting up the soft DIP just as they are on the MVS - Cheat engine for PAR style cheats - Robust power on self test for diagnosing faults - Exception handling for diagnosing software/hardware faults - Miscellaneous debugging stuff Planned future features include: - Slightly faster loading times without hardware mods - Various refinements - Feel free to make a suggestion to the author: smkdan@hotmail.com How to use: * Power on - Power on with button ‘A’ held to access a new hardware test much like an MVS would do when powered on. This method of testing relies on very few components to be functioning in order to run a complete test and is recommended if your system starts resetting, glitching, throwing exceptions etc. Stock BIOS chips do not offer any sort of self-testing for the user. - Power on with button ‘B’ held to access an I/O test. Controller tests, video and audio tests are available. * Initial load - Provided the option is enabled, you will see the main menu after the game does its initial load. Any settings can be applied before the actual game begins and the same menu can be accessed at any time during gameplay. * Gameplay - Hold START + SELECT during gameplay to access the main menu at any time. You can resume the game by pressing start in any page. * Saving and loading settings - The ‘SAVE’ option in the menu saves some currently selected settings in your systems backup RAM. These settings apply to the current game ONLY. During the initial load, the BIOS will automatically load any settings you have previously saved for the current game. The options saved are listed here. - System type - System region - Debug settings - Game soft DIP - Currently selected cheats - Possibly a few more things in the future - A seperate entry is made in your backup RAM for each game you save settings with. When viewing card data, you will see “(game name here) DBG” for each game you save data. The smallest possible size for a save file is used to prevent too much space from being eaten by multiple games. Known issues * The following bugs are already known: - Many games will reset instantly when starting in MVS mode. This fix must be done for every game so it will take a while to make all games compatible - Debug dips do not seem to have any effect on most games ______________________________________________________________________________ 下載；http://smkdan.eludevisibility.org/ngcd/bios.zip 官方：http://smkdan.eludevisibility.org/ngcd/ -- 谷繁田中賢稻葉吉見石川雅矢野中村ロㄧズチェン攝津阿部鳥谷ラミレス涌井岩瀨小笠原井端青木ダルビッ藤川ブランコ森野杉內クルㄧン宮本荒木田中將林昌勇 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.115.180.121
