First of all, thanks to Link83 who made that possible by releasing his regionfree+devkit intro BIOS a while ago.
So today, you know what I am talking about, I release my custom bootROM, with the same features as the one released previously, except that that one has the devkit intro. And of course, it works on the real hardware 🙂
Download: jc-bootROM-devkit-v1.030.zip
Download: jc-bootROM-retail-v1.030.zip (it’s exactly the same BIOS file, just the Readme file has been slightly updated)
To make sure you get what I release, here are the sha1 hashes:
- jc-bootROM-retail-v1.030.bin: 1F385633B2438BAA1984C1194021DCA967B8D095
- jc-bootROM-devkit-v1.030.bin: 96A4B580E26B1DC696004757F588647B8172961A
About note about my VGA/60hz patches: soon, I may not have enough time to work on that until this summer. I’ve made progress with some 240p games (like Bangai-o, KOF, etc.) but not enough to consider them as “patchable”. I thought first that it would something to do with the graphic library that was too old to stretch the game to fit he VGA resolution, but my guess now is that I have to play with the frame buffer and double the pixels and the lines. Don’t know whether it is going to have impacts on the performances though. Let’s wait and see!

Thank you for that bios! Appreciated!
the information is appreciated, could put a pic of kof to see how it looks now on vga?
As I said, for 240p games, I worked on bangia-o, not kof. I mean I gave it a try with kof and noticed that I have the same issue as bangaio. For now I am going to on only a game at a time otherwise I feel I can lost myself!
Retail bios screen
Does this have the retail bios screen or the 3d devkit bios boot screen? Thanks
Hi,
The retail version has the normal boot anim and the dev one has the “3d intro” used the dreamcast devkits.
Force 240p Mode in Dreamcast games
Hi! I’m Linkr2. Someone put me in contact with you! Your work is awesome! : O
Well, I’m trying to get some way to patch a Dreamcast game in order to make ir work in 240p (so it seems you are making just the inverse process haha). For example, for games as GAROU, which run at 480i, when they are meant to work in low resolution. I’m looking for info, hex codes, an all I can gather.
My knowledge is very very low, and you seems to be an expert!
I opened a thread in assemblergames: http://assemblergames.com/l/threads/¿force-240p-mode-on-dreamcast-games.59058/
And I’m posting in other forums in order to get some information. Do you think it is possible? You know which parameters (hex code) are the ones that manage the 240p output of a game?
Any information or help will be absolutely welcome, thanks in advance : )
