TI Z80 / Re: Qt/KDE Port of WabbitEmu

Always cool to see people working on projects for other operating systems! Qt is nice, too; I can't stand GTK+. :P

I bought it 1 year ago, but i'm not sure from what year it actually is :/

If TI still does this on new calcs, I remember reading on the Web one time that there was a manufacturing date code to the right of the serial number on the back of the calcs. I'm not sure where I read this, but it seems to be plausible. For instance, on mine:

TI-82: To the right of the serial number the code is “I-1094Q” (10/94 = October 1994)
TI-85: “CBL I-0795G” (07/95)
TI-86: “I-0897D” (08/97)
TI-89: “I-0600D” (06/2000)
TI-89T: “S-0906F” (09/2006)
TI-81: (Don't have it handy at the moment, but you get the idea)

All of these dates are within a few months (except the TI-86, which I got over a year later) before I received each calculator, so it seems like it could be right.

I'm still hoping to finish the things I have in mind one of these days—I haven't given up on them yet. For most of these I really don't really anything code-wise to show at the moment.

One exception, though, is a TI-89 Skip-Bo game written in C (with TIGCC) which was intended to be a clone of an electronic handheld version that I had many years ago where you play against one to three computer opponents at one of three selectable difficulty levels. If I recall correctly, I had the whole UI (including legal move detection) finished—the main thing missing was the computer player AI, which I hadn't started on. That's where I had left off and haven't worked on it in quite a while. Since I've been releasing all my projects as open-source under the GPL, I've been thinking about possibly releasing this as incomplete source code for now, and perhaps someone might happen to take it and finish it before I ever get around to it. Would anyone be interested in seeing this?

I can easily add more extensions. However, I am unsure about .exe, in case someone uploads a virus or something (that could potentially harm the server)

If ZIP is allowed, wouldn't they be able to put an EXE (or any other type they want) in it and upload that, though?

To be honest, though, I do not recommend only sticking to ogg when sharing music, because most people uses Windows and have to download and install a ogg player. Same goes for WMA files. Despite the advantages of ogg, I tend to prefer sharing music in mp3 format, since almost all computers comes with a mp3 player. On TIMGUL forums, we allowed all music extensions, but only one person ever used wma and few people used ogg format. When those people did, others complained that they couldn't open the file and to upload a mp3 version. In other words, some people might not even bother downloading your file if they are a bit lazy

I wish Ogg Vorbis were more widespread, though. I would be using it if it weren't for the fact that portable music players supporting it are still fairly uncommon. (And, given that it's a license-free format, I frankly don't think there's much of an excuse for manufacturers not to, either.) MP3 may be the de-facto standard, but it's getting outdated. You can cram a lot more sound quality into much smaller files with modern codecs.

People don't check that section when they want games though... :( oh well.

My reasoning is that normally games in the calculator sections contain actual calculator executable files (e.g., 8xp, 8xk, 89p, etc.) for which there is software available on many computer operating systems (including Windows, Linux, Mac) to send it. But in this case, it appears that Windows is required in order to run the software to create a file that can be sent to the calc. So it could be frustrating for someone who does not run Windows to think they are downloading a file that they can use right away, only to find out that they first need to go find a Windows system to be able to do anything.

Also, it seems to be kind of a precedent (under most conditions, at least) on ticalc for files uploaded in the calc sections to contain at least one calc file ready to be sent to the calc.

Hmm... maybe we could add it to both sections in the next version if I include a sample (homebrew) rom and 8xk?

Possibly... That's what was done for gb68k, although the included .89? files probably aren't of much use unless someone has ROMs to convert. (Although one nice aspect of gb68k is that it contains the source code for the PC converter, so even if someone didn't have Windows there's still the possibility of being able to port it for a different OS.)

I know these aren't exactly the most consistent decisions in the world. :P It can be tricky to know where to draw the line with new situations, and satisfy program authors while keeping the archives user-friendy for users. I'm open to suggestions, though.

*attempts to use telepathy to tell the ticalc file archivers to check the pending queue*  :P

Whoa, how'd you do that? ;)

I added it to the win section (instead of 83plus), though, since I only found EXEs in the ZIP rather than calc executables.

That's something I forgot to mention. I really hate this trend of being cheap and using CDs instead of books for things. Luckily, this started after I finally got a decent computer (in 2001!) with a CD-ROM drive. Else, I would have been screwed (and ticked!) as far as getting the programming reference info I needed.
At least there are CDs.  My mom got a new laptop recently.  There was no manual, nor a CD.  This meant she would have needed a working computer with a working internet connection if she had any problems setting up the computer  :o

Whoops, you're right there. That's even worse! Before I had regular Internet access, that's another thing I used to complain about—people who assumed everybody and his dog (and cat and mice and fish...) had the Internet 24/7.  >:( Well, at least I'm no longer in that situation, either. :)

General Calculator Help / Re: Starting game programing
« on: June 17, 2009, 05:06:39 pm »
I don't have any real experience with the 84+, but from what I understand, the TI-89's TI-BASIC is the most advanced "out of the box" (that is, without any extra libraries such as xlib, flib, etc.) and the most flexible. Not to say it doesn't have its annoyances—I really think that all the TIs have a lot of extremely annoying limitations that really shouldn't be there, especially when you're attempting to do large, serious development in TI-BASIC. Though I should mention that since I have done far more coding on the TI-89 in BASIC (over eight years' worth!) than any other calculator, I'm a bit biased here. But I would definitely see what I could do to help anyone with TI-89 programming questions.

I got an HP 50g some time around the beginning of this year (I've always wanted to see what the HPs are like), and its programming language seems to get in the way the least when it comes to large projects out of any calculator I've used. In fact, it seems to have been actually designed for large projects, and some features like the built-in debugger are very helpful. However, as many people say, it has a steep learning curve if you're programming in straight RPN—it's very different and it takes a great deal of practice and getting used to. And there are a lot of strange, tricky areas that I've had to figure out and work around, so it's not the sort of thing to do if you want results very quickly. However, if you have a lot of time to devote to it, there are a lot of possibilities, and there are even on-calc assemblers for lower-level languages as far as I know (though I haven't yet gotten to an advanced enough stage to try them out, so I can't comment on them now).

Ugh I understand your situation Travis, altough with me the difference is that I had some sort of internet access (still very limited, though). My only source was the manual, the reason why I progressed so slowly in programming in my early days of TI-BASIC compared to certain other people on this forum and United-TI.)

I don't feel that I progressed slowly, as I picked up on it quite quickly. Though I have greatly improved in programming skills and practices in general (for any language) over the years through experience and reading things. Like I know how to split things up into separate pieces that I code and test separately. I still remember in my early, inexperienced days when I used to spend 2–3 weeks writing code for a whole program before testing it, then spending the next 2–3 months after that managing to get it to actually run and then weeding all the bugs out. ;D I'm glad I don't do it that way anymore!

I couldn't use the manual to learn programming, because I got the ridiculously thin one with my 84+SE. :(

Luckily, this started after I finally got a decent computer (in 2001!) with a CD-ROM drive. Else, I would have been screwed (and ticked!) as far as getting the programming reference info I needed.

Welcome to Omnimaga TravisE!  Now we really have some pull over at

Oh, and here are some complementary Omnimaga peanuts

Thanks! Wow, that's a big bag. ;)

But travisE welcome. Maybe you will eventually get the temptation to make the grayscale first person shooter soon :D


I've always had lots of calculator project ideas, but never get around to them since I have 7,203,992,230,499 other hobbies to juggle around. I'm trying to shoot for getting them finished by the year 6000, though. ;)

I think the clock feature on the calcs can be extremely useful. I was excited when it was first added to the TI-89 in the form of an AMS upgrade. You can program a lot of highly-customized, advanced time-related programs that a standard clock or watch can't do. Another nice thing you can do is date/time-stamping. I released a BASIC Yahtzee game for the TI-89 a long time ago that did this for the high-score list, because I found it nice to be able to see how long ago I made each score. If they had added an alarm feature, it would have been even more useful (the HPs have alarms, and you can set them to run whatever program code you want when they trigger).

To answer the original topic, I'm another of those really strange people who learned programming by actually reading the manual (naturally, since I've always been addicted to reading manuals for some reason ;D) and developing my skills by doing it for many years. Not that there was much of a choice, though, since this was in 1994, long before I had any kind of Internet access, and I didn't have any friends who did programming.

Hi, everyone.  A lot of people probably don't know me since I'm not too people-oriented and don't socialize much (heck, I think it took me several years just to figure out that most of the discussion activity actually took place outside of ;)), but I'm the other recently-hired file archiver over there. Anyway, I just thought I'd hang out here from time to time to get a feel for what's going on, especially in the area of the TI-83+/84+ where my knowledge is quite limited, and answer any questions or concerns that I come across that I'm able to. Well, see you later!

I processed that file. :) I think it's notable, so I pointed it out to some other staff members. However, I think they're extremely busy, as I haven't seen much of them lately.

The reviews (like most of the other parts of the site) are automated, but Duncan for some reason has only been processing the reviews every few weeks. Maybe he's just been really busy lately.

People actually submit reviews fairly often (mostly for files that have recently been posted on the front page), but quite a few of them have to be rejected for various reasons, like they are so short that they contain really no useful information (e.g. "Cool game!" or "I never could get this to work, so it's of no use to me"), or they are actually problem reports or concerns that should have been emailed to Nikky or me to be fixed, or they were written by someone who couldn't RTFM, etc. I think Duncan does an excellent job filtering out the junk and extremely unfair reviews, though it's too bad he can't process them more often.

News / Re: Illusiat remake for the TI-81 and some discoveries
« on: December 20, 2008, 10:29:48 pm »
Well I thought this could maybe make news, both because of how in depth it is for a TI-81, being the first TI-81 RPG to be released and the first upload in the TI-81 directory since maybe 5 or 6 years, but due to some events that occured one year ago in the community I requested the removal of my entire author profile there (altough it took them 4 and half a month to remove it) and am not planning to upload anymore stuff on any english TI site in the future. So since only feature programs in their own archives (at least since Michael_V was hired as news editor)

That's too bad, but since you're the author, that's your choice.

As for the game itself, there might have been some errors while I typed it by hand. The GridOff function is avaliable in the MODE menu. I added it because I was planning to add graphical magic animations, but then I found out the only way to turn axis off was to Dim the window so the dots and the actual axis are out of the screen so it was too much hassle to fit animations afterward in the limited RAM. However when I decided to go with home screen animations I totally forgot to remove the GridOff from the code. I actually started typing it before adding the home screen animations so I don't remember if it was on the real calc.

I thought I might have been overlooking it somewhere. :) I didn't even remember that GridOn was actually available on the TI-81, but then again it's been years since I touched the thing.

Welcome by the way :)


I think I got up to the last boss (is the last boss where it says “Now see my true power!” and you have to do a second battle immediately?), but unfortunately my TI-81 locked up for some strange reason (no idea why, it's never happened before) when I left it on on the Illusiat main menu for a while, and since I don't feel like typing it back in and starting over at the moment, I guess I'm done for the time being. ;)
