【推荐】japanese_cake新放出的dc bios

原文:http://japanese-cake.livejournal.com/10056.html
Release: Custom BootROM v1.032
Hi there,

A couple of months ago, I thought I was ready to release my new bios. Unfortunately for me, at that time, I was really busy and my bios mod started to show weaknesses. As I don't have the right soldering equipment, I had to work with my Dreamcast and all its little faulty contacts. I worked hard to get the reset exception working correctly... actually way more than I should have! The reason? On my Dreamcast, the faulty contacts I mentioned were crashing the Dreamcast upon reset! I took me quite some time to figure this out :/

That was quite unfortunate for me but at least it gave me the opportunity to have a glance at other things. I explored a bit how the region protections games like San Franciso RUSH 2049 have and came up with a solution that fake the system region. Later I decided to force the video signal to output a 60hz refresh rate (more details in the readme file) and so on and so forth. So now the bios I'm releasing today is way more advance than I planned initially.

With the holidays coming, I don't want to hold it any longer. However I prefer to warn you beforehand: even if I tested most of the features, I can not guarantee that everything is 100% working (and constructive feedback is welcome). I am sorry for this but no worries, the bios does not contain some kind of bad-ass code that could destroy your Dreamcast ;)

I tried my best to add new features, improve compatibility with some naughty retail games. But it comes with some drawbacks: no cheat disc until I release one compatible with my bios, some independent games like Pier Solar do not work anymore (again, more details in the readme file). I will address those problem later. For those using GD-Emu, you are probably also using the GD-Menu app Neuroacid created. Well here again it doesn't work anymore, but soon a compatible will come to light! By the way, kudos to neuroacid who saved me time and helped me a lot for my testing!

Ok, that's enough talking for now, let's check the features out:

bootROM v1.032 Retail & DevKit Changelog:

  • In BIOS menu to update the following bootROM settings (Boot animation color, SEGA license screen skip, MIL-CD/backup direct-boot, Dreamcast main menu scenery perspective and color)

  • Skip the "set date/time" screen

  • BIOS video mode forced to 60hz

  • Auto region patching for GD-ROMs

  • Internal changes for future updates

Please read the readme file to see the complete list of features.



bios设置画面按开始键可以设置一些有趣的东西,比如跳过sega检测,跳过设置时间,bios画面变更 等等等等,有兴趣的可以刷一个试试
