New Dreamcast Bios hack!

[Dark Hayabusa]

Japanese-cake is a page on which your administrator presents its latest developments regarding the Bios hack Dreamcast.
Below are the changes in the Bios:
.- Region free: boot GD / CD from any regions. The J / U / E flags as well as the protection area lies That slots in the AIP (AKA IP.BIN) are now simply ignored.
.- No VGA flag check: no matter if the game Supports the VGA output, it lets the boot. There are games That Supports the VGA cable but for some reason the VGA flag in the AIP is not set. The use of a boot CD was just thus needed. Now, you will never get the annoying "This game does not support the AV Cable That is Currently connected to the main console" anymore.
Extent .- Bootfile check: allow a game to boot even if STI bootfile, more Commonly called 1ST_READ.BIN, is not located on the outer part of the disc. I do not know Whether it can be of any use for people using discs. However, for the lucky owners of ODDE for Dreamcast, you can re-build games' track 3 without any padding. For instance, with "DreamKey 3.0 v1.001 (2001) (Sega) (PAL) (M8) [!]", The track03.bin is ~ 1.10GB. Re-building the track (track03.iso) using the following command: mkisofs -C -G IP.BIN DREAMKEY3 0.45000 -V -l -o track03.iso made the data will track03.iso way smaller (only ~ 93MB) . Also homebrews can be rebuilt to GDI So THAT 0GDTEXT.PVR the texture shows up in the audio player
Display .- bootrom version: the current version of the bootrom Appears in the up-right corner of the screen.

Swat think this can help a lot to some compatibility issues...

This BIOS really needed only for playing from GD drive.
DreamShell ISO Loader ignored region, VGA and bootfile checking in general.
So all of this can't help to DS with anything.

Custom BIOS goes to version 1.031

Цитата:Hi there,

I have been working quite a long time on that version. And not necessarily on the features that may sound hard. Changing from white to black the fade-in color when booting a GD-ROM took me a couple of hours. I was looking for something that does not exist in the code so that kinda explains why That version is intermediate in the sense that I needed to be sure that backups can boot without a system-reset before going any further in my research. Now that I know it is possible, many things are worth considering in the next versions. The first things that come to my mind are the extra region protections games can have (RGB/PAL protection, system broadcast check, etc.) then a in-game-reset that is working in all games. Finally, I am considering working on the bleemcast issue. As far as I know, it's the only game that does not like my bios....
Oh, yeah, speaking of that, I really need support. All my GD-ROM drives are broken and I need to get a new one. I would also appreciate if someone could make me an offer for a black Dreamcast, with its box. I am looking for an almost-new one (scratch-free). The US Sport Edition would even be better Well, it's time to let you download the "stuff" and enjoy it!

New features (for a long description, see the readme file):

SEGA License screen skip
MIL-CD/backup direct boot
Black fade-in color while booting from menu
No VMU copy-protected file check
