In ideal world, or simply in the world we were living in until a couple of years ago, goods were still made to last. How many of you are still using their old consoles or computers? Today's consumption model has been forcing us to renew our electronic appliances, phones, computers with no warranty that the new models we buy are as efficient as the ones we throw away. Once again, I have my laptop playing with my nerves and I have no other choice than sending it back to aftersale services. Hopefully here in Europe, any computer hardware brands have to provide a two years warranty to their consumers, even if you have not spent a dime on an extended warranty like Apple Care or whatever.
All of this to say that I postpone the Dino Crisis release by at least a week. But no worries, it's almost ready. I have also read that my RE:CV patches are just partialy working. As I said, I don't play those games so this is probably why I did not notice that the game was switching back to 50hz while/after playing FMVs. Now that I have enough experience in patching Capcom games (thank you Dino Crisis :), I see what is left to be done. Anyway, I will fix this and also provide some support to have the RE:CV X patched as well.
I will also release a CDI version of SoA, based on Echelon release. I still don't know if I will keep the trainer though. Let me know whether you want it or not ;)
I have been hesitating a long time whether I should release this or not. But, after all, I don't see much differences between releasing part of a game or the entire game image. So here we have a shared folder that contains patched GDI images I made. At the moment, I only have games to which I've added the VGA support. Basically the boot file has been replaced by the patched one and the boot sector's (IP.BIN) VGA flag has been set so that the game can boot with the VGA cable plugged in. Regarding the tracks format, I kept the original raw/binary (mode1, 2352 bytes/sector) file format but as I modified part of it, I fixed the ecd and ecc vectors so that any software sees the image as legit.
Among the games there are in the folder, there is a one I haven't released anything about so far: it's "MTV Sports - Skaeboarding Featuring Andy Macdonald v1.002 (2000)(THQ)(PAL)[!]". You can also find its patch in my patch repo: jc-dc-patches.
I don't know for how long I will keep the sharing open, so I encourage you to make copies.
Note: The version of SoA is in the GDI format so unless you split the game in three of four discs or use compression technics (like for instance echelon's release) you won't be able to burn a copy. However, I have a patch for Echelon's release. Once I am done with Dino Crisis I will certainly release it.
Back from my vacations, I was contacted about a potential patch for the PAL versions of Dino Crisis. As with Resident Evil: Code Veronica, there are several PAL versions (UK, French, Spanish, Italian and German) and except for the UK one they are all localized with subtitles during the game and the FMV playback.
Unfortunately, the game has no VGA support. The game can boot in VGA mode with the disc swap trick (or one of my custom bioses) but the FMV playback does not work on VGA display. Furthermore, if you force the game to NTSC-60hz, the subtitles are not in sync anymore.
This is what you would get with a "simple" VGA patch:
But DC is a bit special: it uses the Sofdec middleware stack to display FMV. Let's patch it for VGA then!
I've found it really challenging to patch this game. While the game itself plays flawlessly in VGA, the FMVs change significally the complexity of the patch, at least the way it is coded. Basically it's like opening a can of worms. And if you add the subtitle thingy on top of that, it's a nightmare! But after spending some (read many) hours on dissassembling the game, I think I nailed down the way the subtitles are generated.
Below some footages to illustrate the different stages of fixing the subtitle texture.
Now remains fixing the subtitle delay (50-->60hz). I know where to patch but I need more time to implement a way to remove the delay all at once.
So yes the game can be played on VGA and yes a patch will come to light :)
UPDATE: Yes I still am working on the patch. I will post more details next week. Everything is patched and works correctly (even/especially on real hardware). There is one glitch I am struggling with though... hope I can overcome this soon :)
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 problems 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 the 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.
I feel like some people like to claim that it is impossible when they fail to overcome problems. Fortunately, their vision has a limited influence. If I listened to all the negative comments about my projects, I would probably end up being like their authors, spreading my frustration over the Internet.
Anyway, that is not the point I want to talk about. Today, I am happy to report my progress. Let's start with the bad news. In its current state, my next bios version cannot boot cheat discs like Action Replay/Gameshark/Code breaker and GDMenu. I know why and there are solutions to this. The good point is even though some people state that it is not possible, the beta-bootstrap I slightly modified works flawlessly with MIL-CD/backup, including the system reset. I can even add that I knew it would pass the holly protection before testing it on the real hardware. Pretty cool isn't it? But to be honest, my moves are limited but I hope that in a near future I will be more free.
In short, I could release my bios right now, and release the "patched" cheat disc later. But I am not sure yet that this would be the best solution to introduce the custom cheat-disc for my bios, specially as there is a chance that I will overcome this issue. Booting custom bios is already a difficult task for users and I don't want to bother them with a "special version" of games/applications. Anyway, whatever solution I come up with, the compatibility is not going to be impacted.
Pending the next BIOS release, I decided to update GDROM-Explorer. I received feedback some several people saying that some files were corrupted after extraction. Well that was a really silly bug, a piece of code I forgot about when I was doing some code refactoring a while ago :( Thanks to tormod who saved me a lot of time comparing files, I could easily nail down the problem. I am sorry for those who wasted time on this. The good news is that, even I took me more than a year to update my program, you finally have now a fixed version!!!
A couple of weeks ago, I was feeling comfortable enough to release my next custom bios before 2016. Then I postponed the release date to February. Right now I cannot commit on a release before March. I am sorry about this but you have to understand that it is also frustrated for me! I have been working hard in the next version despite a busy schedule and substantial personal changes.
The good point is that the version 1.032 is "feature complete" and is working properly. I introduced new features and cool customization options. I have only one thing that stops me from releasing my custom bios: the holly check.
As you may know, at boot time the bios is copied from the chip to the RAM and the Holly controler performs some sort of a checksum to determine whether the bios is legit or not. If it is not, the GD-ROM drive is locked and ypu cannot play any game. So far I have been using code (bootstrap) from a beta naomi bios (a beta version The House of the dead 2) in which only a small part of the bios is checked, leaving the rest up for modifications (Thank dknute for the intel and MetalliC for the first implementation!) That is the way I validate my code on real hardware. Then I inject my patches in the retail bios and more or less bruteforce the Holly check. Right now I have to make the bios pass this check, this is the final step. You may ask "why not releasing the bios with the beta bootstrap?". Well, here is the heck: this "beta" bios does not support the manual reset (read soft-reset) so you are not able to boot milcd and play with boot discs. I patched the beta bootstrap to handle the sof-reset but as It modifies to the data used by the Holly controller to unlock the drive (more precisely the G1 bus) I face the same issue again: the modified beta code has to be altered to pass the Holly validation. So here I am, trying to get lucky! It takes some times (that I will have next week) but I feel confident. I know that it is not because you change kb of data that this step is harder. I was already able to pass the check with a bios that had more 32kb of data different from the original bios. If by chance I can make the beta bootstrap code with the reset pass the Holly check, I will not have to bruteforce any other custom bios. It is definitely worth trying!
Our favorite console is definitely not dead and not even dying! Every year I am so surprised to see how many games, mods, prototypes, tools and accessories get released. I really like that system. I do not own any of the last generation consoles and I think it is better that way. I am so furstrated to see that when you buy a game for new systems, the first thing you have to do is to download a small 1 or 2 GB update, because of course the game is still in a sort of non-official "beta" version. So you basically pay video-game editors to help them debug their games... Well I prefer to live in the past, where games were made by passionate people, carrying values other than profitability.
With Christmas coming, I really wanted to release a new version of my custom BIOS but there is a lot happening in both my personal and professional life. Even if I may have differently, I am not going to release the BIOS before January. First, I have technical issues: my modded Dreamcast seems to have a loose electrical connections somewhere and I do not have an iron at my place to fix this. Second, there is something that is not working correctly with my new BIOS and this problem cannot be neglected. Finally, the release is made up of two elements: the BIOS itself and its configuration tool for the customization and I am late in the development of the latter.
Pending the next release, I have created a youtube playlist with two new videos. I hope you will like them.
Also I would like to thank the people who donated. I will probably spend that money on a new iron ^^ Thank you!!!
Quick update regarding the next custom bios. I have been working a lot on this version (v1.032) but unfortunately, the most important changes will be barely noticeable for most players. At least, starting from the next version, it is going to be easier for me to make progress and offer what people have always been waiting for. Aside from the next version, I have also worked a bit on the customization: changing the swirl and background color is definitely possible. I don't know whether I can release that now though.
I would also like to emphasize that I have spent quite a huge number of hours on this project and even if I am a big Dreamcast fan, I still am a human that needs motivation/support. I contribute to some other projects or platforms, money or time wise, so I would really appreciate if you could the same, as a compensation for my work. By doing so, whatever the amount of money you give, you then join the others ide of the scene, where you can legitimately claim that cool stuff happens not only thanks to me but also thanks to you ;)
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):
And for those that don't really what I am talking about, I made a short video:
Update #1: someone gently reported that once a GDRom has been detected by the console, no MIL-CD/backup can boot up. GDEmu and UGC are fine though since they do not emulate the drive lock protection.I did not know that, so for now, until I'm able to test and either fix or disable the direct-boot feature, I remove the download links. Thank you.
Update #2: The next version V1.032 is almost ready. I'll put a release note about the MIL-CD issue you can experience. In the meanwhile, as some people asked, I put back the link to download the v1.031 release.
