One period of the video game industry that has received a great deal of attention is up through the 1980s. Further, video games tend to rely on other resources like operating systems, network connectivity, and external servers outside control of users, and making sure these boundary aspects to a video game are preserved along with the game are also essential. The media formats of the early days of computer gaming, relying on floppy discs and CD-ROMs, suffer from disc rot and degrade over time, making it difficult to recover information. However, as technology advances, these older game systems become obsolete, no longer produced nor maintained to use for executing games.

Unlike some examples of other forms of media like books, art and photography, and film, which antedate the mid-20th century and which can be preserved in a variety of formats that are not prohibited by more-recent intellectual property (IP) laws, video games typically require specialized and/or proprietary computer hardware and software to read and execute game software.
There is also interest in the preservation of cancelled video games that were known to be in development, as coupled with the reasons for cancellation, they can provide a understanding of the technical and creative aspects, or lack thereof, at the time of the game's development.
6.12 The Museum of Art and Digital Entertainmentīesides retaining the ability to play games from the past, preservation of video games enables research on the history of video games as well as ways for developers to look at older games to build ideas from. 6.11 Hong Kong Game Association (RETRO.HK). 6.10 National Software Reference Library. The new BIOS can be flashed through Dreamshell, but only if you have replaced your Dreamcast's BIOS maskROM with a replacement flashROM or added a secondary flashROM.Ĭurrently he is working on a newer version that is compatible with bleem!, but also would have the ability to bypass additional region checks that some games impose, as well as a software-reset button combination that would work with all games. Fade-to-black upon boot normally when launching a GD-ROM from the BIOS the Dreamcast fades to a white screen then cuts to black, now the game just fades straight to black. Disable VMU file protection games that set no-copy flags on their game saves can be copied to other VMUs right from the BIOS now without third party utilities. No reset for MIL-CD boot normally when inserting and launching a MIL-CD disc from the BIOS menu the system resets and displays the intro all over again now it boots directly to game just like with GD-ROMs. Unfortunately, this breaks compatibility with bleem! until japanese-cake can fix it in a later build.

SEGA license screen skip once the intro is finished displaying, the IP.BIN bootstrap code is executed silently without having to wait for the Sega license screen to display for 6 seconds before the game starts. Displays bootROM version on the top right corner of the screen so that you know which version of the BIOS you're running. No bootfile LBA checks for GD-ROMs this allows easier editing/shrinking of GDI files for people with GDEMU hardware. Disable of VGA cable check, meaning games that support the VGA cable but don't have the VGA flag set in their IP.BIN will now boot without an error message and won't require you to plug/unplug cables. 
Choice of normal intro or devkit intro (as in Link83's BIOS). 
Checking of J/U/E region flags disabled (as in Link83's BIOS).It is based on Link83's previous BIOS hacks that disabled region checking and allowed the user to have the choice of using the Katana devkit intro instead of the retail one. Japanese-cake has been working on improving the Dreamcast's BIOS through extra features.
