Are you sure about there being no level data in compressed blocks? I did some corrupting(bitwise inversion) a few months ago of the SM64 ROM(Japanese) in 64KB chunks and the found a single byte at 0x400212(or 0x400213 in the correct byte order) that would crash the game upon the loading of bob-omb battlefield if changed from 0. Screwing around there, I was able to mess up parts of the bob-omb battlefield ground polygons(objects in the level still acted like the ground was still in the same place). I thought that was inside a compressed block. I'm not so sure now.

Finally, my standard lecture about sharing info. I beleve that it is best to post information early and often, not wait for it to be complete or exactly right. If someting is hard to understand, someone else may have another insight into it. In case there is a loss of interest or too much work for one person, someone else can continue without duplication of effort.

The compressed data block that starts at 0x3fa310 runs to(but not includes) 0x403abe for a total compressed size of 0x97ae. 0x400213 is within that range and part of the last section of the compressed block. Here is a line from a hex dump of the ROM(corrected byte order):
0400210: 28 28 28 00 13 00 04 00 10 57 5e e6 98 f8 7e f9  (((......W^...~.

I think that the area that I messed around with to change the polygons was within the next 256 bytes after 0x400213. I also remember changing the three 28s to make the level a little darker, but that might just have been in my head.

Was there ever a good reason for making a rule against bumping in the first place?

Most of the posters in this thread seem to think that closing a bumped thread serves no useful purpose. I'd agree.

I'm using Debian 3.0 aka woody. I don't use a bloated desktop enviroment like KDE or GNOME. Other than IceWM and a few apps such as Galeon for browsing the web, Anjuta for an IDE, and Balsa for e-mail, I mostly use command line tools from xterms. I often have a dozen or more xterms running at the same time.

Posted on 10-30-04 10:17 AM, in RomHacking Consortium: Proposal Link
This sounds like a great idea. Here is some more stuff to consider.

I urge you to reject documents in word processor formats, or any format other that plain text or HTML. I like to read stuff in an my web browser. If the author of a document doesn't make the document availible in plain text or HTML, convert it.

Ticalc.org has a great feature that allows people to view text files inside archives without downloading the whole archive. I wish more rom hacking sites had such a feature. To support such a feature and to prevent people from having to get extra archive software, I think that it would be a good idea to ban archive formats other than ZIP. *cough*RAR*cough* Normally, I would suggest that tar.gz should also be allowed, but in tar.gz archives there is no index, and even getting a list of the files in the archive would require decompressing the entire archive, thus using a lot of CPU time.

Another thing to consider is a Advogato style certification system. At Advogato, users can certify other users as "observer", "apperntice", "journeyer", or "master". The server calculates a final certification for each user by how much trust flows from the site owners, and those that are presumed by the site owner to be masters, through the certifications. Thus, while any user can certify any other user at any level, those who are trusted more have more of an impact on the final certification. SourceForge has a certification system based on the Advogato system.

You may also want to look into adapting GForge, a which is based in the last GPL release of the SourceForge software. It has some features, such as file uploads, project pages, and account management, that would be useful for your proposal. It should not be too hard to adapt because it is written in PHP and most programmers here know PHP. On problem is that it will probably not work on standard web hosts. It requires PostgreSQL instead of MySQL, and may require root access to the server to install.

Posted on 10-30-04 11:29 AM, in Do the people at Nintendo use editors to make their games? Link
My guess is that back in the days of the NES levels tended to be created on graph paper and then typed into a asm source file using hex data pseudo opcodes. After that, levels would be created using a simple editor, simpler than EggVine or LM. Nowdays, 3D games tend to be created using commercial CAD programs and exported to the game's native format by custom plugins.

We will probably never know for sure what Nintendo used for SMW. It is possible that Nintendo reused parts of thier SMW editor for YI.

I've read that ID used a custom editor that ran on the NeXT platform to create levels for DOOM. I'm not sure, but I think that the source code for it has been released.

(NeXT was a computer company started by Steve Jobs after being kicked out of Apple. NeXT has since been acquired by Apple.)

I will certainly take this into consideration, and if we are unable to aquire the necessary SQL specifications, perhaps we can either find or create a system similar.


I looked at the code for mod_virgule, the Apache module that runs Advogato. It is written in C and runs off XML files. The trust metric system could be adapted to operate with a MySQL database. In order to make use of it, a host that makes cron(the Linux/Unix equivalent to Scheduled Tasks) available to customers will be needed.

Getting a patent is not cheap, in the US the filing fee is currently 790 USD. After a patent has been examined there is a issue fee of 1370 USD. There are also maintenance fees that are required to in order to prevent the patent from expiring.

Getting a patent is probably not even worth it.

Sending a copy to yourself by registered mail is not considered strong enough proof of prior art to hold up in court because it is possible to tamper with it after seding it to yourself.

It should not crash if TargetString is big enough. Could you post the declaration of TargetString, or, better yet, the whole function or source file?

I would also suggest using snprintf().

After less than a minute with Google I found this and this.

Posted on 11-13-04 10:54 AM, in Buttons at Bottom of Board Link
If the buttons at the bottom ever get changed(or even if not), could that 2K block of data that is part of the donate link, which is really a form, be removed? Perhaps the form could be moved to its own page and the button link pointed to said page. Perhaps it could be removed completely.

BTW, does anyone know why the Firefox link is inside the donate form tags? It looks like whoever added it was a bit hasty.

Posted on 11-18-04 10:42 AM, in Do you browse the web using an admin account or a restricted one? Link
I almost never browse the web as root, and I rarely download random software I encounter. If I need root powers, I just bring up an xterm and use the su command to get a root prompt on said xterm, or I switch to the first virtual console which I tend to leave logged in as root.

If I need to install software, I will first look for it in the Debian package archive. If I need software that is not in the Debian archive, I prefer to download the source code, compile it myself, and then run the compiled program from wherever the compilation script places the binaries. When I do the latter, I do not need to log in as root, because the software was not installed.

I know of no cut and dried instructions, but these pages might help:

It was graphite. When the cover was blown off of the reactor by excessive pressure, air came in contact with hot graphite in the reactor, starting a fire.

To learn how to fix some, but not all, of them and set up forums, go to http://www.cymoro.com/abhacks/abinstall.php(read this first to see if you can use AcmlmBoard).

Posted on 11-27-04 01:06 PM, in Best Linux Link
I have not used an external hard disk, but I think installing Linux on one may be a problem. The BIOS and bootloader will need support for the interface that the drive uses, probably USB or FireWire. If it is possible, it will probably not be as easy as installing on to a ATA(IDE) or SCSI hard disk.

I'd recommend backing up your files to the external hard disk and partitioning the internal hard disk. Reinstall Windows on one partition and Linux on another.

Posted on 11-27-04 01:49 PM, in Good * old fashioned `annoying` SQL `question`('s'); Link
You could write something like:

$res = mysql_query("SELECT * FROM footable");
$rows = 0;
while ($omg[$rows] = mysql_fetch_array($res)) {
$rows++;
}
mysql_free_result($res);


Then use $omg[row][column] to access data. The $rows varible will hold the total number or rows.
