Updated the Mille Borne XB game in MyGames to version 3.40. I added sound, voice, sped up the game in several places and fixed some long standing minor bugs. Enjoy.
January 25, 2021
After thinking about it for a while I decided to focus on just the TI99 on TI99resources. So I am removing the only two things that weren’t TI99, the MAME packages: 99/8,99/2,Tomy-Tutor and the Geneve. (OK, before someone says, ‘the Geneve was TI-99’, I don’t see it that way. Yes, it used the TI99 PEB but you removed the TI99 out of the way to use the Geneve. It had it’s own keyboard, audio and video. After you got the Geneve you could effectively toss your TI99 console.)
Trying to support the TI-99 properly takes all my efforts on this website (I have just found an additional dozen or so games that I need to add this month) and adding these other systems at this time would just make the site more directionless. Plus I’m starting to run out of file space.
The 99/8,99/2, Tomy Tutor and the Geneve MAME packages from the MAME section are now here in this Atariage post: https://atariage.com/forums/topic/304601-ti99resourceswordpresscom/
Added TI99Sim Linux based emulator to the emulations page and added back the link to TI994w that some how lost.
Emulation is now it’s own menu page.
Updated the Geneve MAME/MESS package with better documentation, a better OS boot drive, tested software and more stuff. I have it boot up with a green screen (I think it looks retro cool like that) and the packages that are installed have been tested to, mostly, work. Lots more documentation which the Geneve was sorely lacking. I steer away from TI99 emulation except XB and have stayed, mostly, with native Geneve software, of which there really is not much. The mouse in MAME sometimes works and sometimes doesn’t in the Myart. A real system that ‘could have been’.
In the MyArcXBII directory I created yesterday I added a second version on MyArcXBII that also adds the capability to boot the PCard. In MESS/MAME options-DIP switches turn on PCard to start the PCard after a hard-reset. Turn same switch OFF to go back to MyXBII.
Added MyArc Extended BASIC II to MAME packages. Everything you need to run a full MyArcXBII in MAME or MESS. Must use version 221 and higher to work.
Updated the manual for KXBII to version 3 to correct some errors and highlight a new SAVE procedure. Updated the Uno game in Mygames with colors in the KXBII version that don’t look so hideous on a real TI99 and made some other fixes and additions to both versions.
Added an MBX section. Includes game software, manuals, ads, pictures and @pixelpedant’s Youtube channel piece on the MBX.
Added in 3rdPartyGameDisk:
Backgammon, Baseball, Bouncer, Casino Solitaire, Death Drones, Garbage Belly, Haunted House, Key Quest, Khe Sanh, Laser Shield, Moonbeam Express, Stone Age, Strike Force 99, TI Casino, Titanium, Western Dealer and Zero Zone.
September 27, 2020
Added a basic search function on the sidebar in Software and Documents. To search all files click the link to SEARCH to the LISTING.TXT text file at the top of the sidebar. Then use your browsers search function, with the text open, to find the file that you want to view or download.
September 26, 2020
Added a new FAQ section. It links to some awesome resources for information on the TI99: arcadeshopper FAQ, nouspikel tech pages, ninerpedia and TI99/4a-pedia. Also added Atariage TI99 forum topic of links to other software and hardware sites.
Added in mygames section a game I re-created that I had submitted to the TI99IUG many years ago – Super Hiway Chicken Plus. I wasn’t able to find this game specifically in the old IUG on WHTECH but that’s not surprising. the IUG usually changed the name and removed the original author from the listing. plus, there does seem to be some files missing from the IUG composite. It’s a Chicken or Freeway variant that was a much improved modification of another IUG chicken game and yes the name is a bit over the top but hey, I was a kid. Kinda surprised how much I remember of the game to recreate it. Can’t remember where I put my keys last night but sure can remember code from 30 years ago. 🙃🙂
Had to remove MusicPro as it seems to be defective. It locks up when loading sometimes. If I get it working reliably I’ll report.
Added Music Pro by Asgard to applications.
added Disk Manager 1000 v6 manual under C99.
added games 3d-bowling, aperture, BHXP1, core war, dow4 gazelle flight simulator, galaxy, hordes, khe sanh, live tomb, maniac, micro adventures 1-6, nonogram, ring destroyer, pyjamarama, strike 3, ti99opoly & time lost – thank you sparkdrummer @ Atariage for the assistance.
added in 3rd party game cartridges:computer war, frogger, intercept, muchman II, popeye, spys demise & strike 3
also in 3rd party disk games: astromania, clear to action, diablo, haunted house, legends, legends 2, living tomb, mr, frog, night mission, panzer strike, startego, sub commander, warewolves & wanderers, wing-it and wizard’s doom
added TI Italian User Group to youTube videos.
more games added: Aztec Challenge, Tennis, Wizard’s Liar, Wizard’s Revenge, Wit Series of Word Games, Moonbase Alpha 2019
added under Documents/Hardware a SAMS section (Super AMS)
added adamantyr’s ‘Crafting a vintage CRPG’ to developers.
added TI-99/4a Videogame House – nice list of games, information and trivia for the TI-99 line.
added Wing War in 3rd party games
Also found I forgot to add the 2 E/A disk to the E/A software; now added.
Added Jedi Matt 42 & Arcade Shopper to Youtube videos under ‘Other Sites’. Worth looking at. In fact, check out all the great creators of Youtube videos covering the TI99. Lots of instructional videos, demos and games play. Most assuredly worth your while to check out.
also added the Brewing Company to list of online stores.
added Wagner’s Tech Talk – There is a lot of really good videos on this site detailing such things as TIPI, FinalGrom, Stuart’s Internet Brower and much, much more. Included with the videos are list of parts, resources and just about anything you need for the project. Very informative site.
Added PLATO courseware. Includes the cartridge, all the courseware disk as an individual download and all-n-one zip download. This is a fairly well made learning package that holds up well even in these days.
added document attached to link to E/A docs which is a list of all the files in that directory. here is the list:

Added PROJECTS section where I’ll include some of my projects for the TI-99
July 4, 2020
Happy US 4th of July! stay safe, mask and social distance.
Today added some Myarc docs in Hardware Myarc. They are Myarc Memory card, Personality WDS-100 user manual, Myarc XBII manual and appendices (thanks @blackbox on Atariage for all your hard work) and put SpaceSpace II in the Myarc section (yes I know it’s not Myarc) since it’s used with Myarc XBII a lot.
Cleaned some misplaced files in the Scott Adams Adventure section. The actual disk with all the games was missing and another file was mislabeled. (thanks @majestyx of Atariage for the catch).
July 2, 2020
added J&KH Super Extended BASIC (SXB). this looks like a fairly interesting XB extension that adds database, string and some graphics capabilities.
added @Shift838 store to the store section under other sites.
added hardware section with 77 hardware documents in the documents section.
Added compilation area to software.
In this directory is some of the more well know compilations of software. Below is the description of what they are and where they came from.
The Altman fairware library was maintained by several different user’s groups over time.
Amnion IUG is the library of the International TI User’s Group.
BCS would be the Boston Computer Society library.
Chicago TIUG is the library of the Chicago TI users group.
Tigercub would be Tips from the Tigercub, which showed up in a lot of disks he sent out–and which appeared in many different newsletters as well.
Added TI Disk Games section with Tunnels of Doom as 1st entry. TOD software includes three TOD adventure disk and TOD editor. Also uploaded TOD cart-on-disk to that area. There is minor glitches in opening credits on cart-on-disk version otherwise is fine. also uploaded the TunnelsofDoom.rpk for those who want the cart.
added Barrage, Return from the Isle adventure and SabreWulf v.1.0 game in 3rd party disk.
Added cartridges Barrage, Tris 2, Sabrewulf v.1.3 and Scrabble to cartridges.
June 26, 2020
Added ‘3rd Party Games on Disk’ sections.
Disk games added: 4A-Flyer, Airline, Beyond Parsec, D-station I&II, Junkman Jr., Mr. Chin, Pitfall, Road Hunter, Rock Run, Spad XIII, TI Runner, TI Scramble and TI-Lander.
Added Driving Demon to 3rd Party Cartridge Games.
Added a TI-PHM-listing to TI Game Cartridges.
June 25, 2020
Did some house cleaning and corrected the software files that didn’t have manuals and visa-versa. Removed, for now, Breakthru, Donkey Kong, Frogger, Jungle Hunt and Moonsweeper because I didn’t have any good manuals. Will re-post when I find good manuals.
Mizapf at MAME has, or will soon be, updating the TI-99/2 emulation to include a 32k memory module. from MAME post Atariage forum:
You may be glad to hear that in the next MAME release (or the one after it; it may be too late for next Wednesday release) the TI-99/2 will offer an expansion slot and a 32K memory expansion. I never saw it in reality, but let’s just assume that it could have existed.
mame64 ti99_232 -hexbus hx5102 -flop1 ti992testdssd.dsk -expport ram32k
I tested it with some BASIC programs, and it seems as if it actually works; I could load a TI BASIC program of 9 KiB size. There seem to be some issues with larger files, however: The screen space gets overwritten, you see some text on it. Note that you have to give it some time to parse the program; this takes up to 10 seconds and more, showing a blank screen. (I thought it crashed, but the cursor suddenly came back.)
June 13, 2020
Added under Documents-Games a listing of all the games software & documentation link to .PDF
June 9, 2020
Added Rich Gilbertson’s Youtube site to Youtube Links on Other Sites. Rich is the creator of RXB Extended BASIC.
Also added RXB Extended BASIC 2015.
June 8, 2020
First a shout out to @schmitzi, @blackbox & @omega-TI for all their tireless work in scanning and merging the documents that I don’t have. WELL DONE!
Added Statistics to TI Productivity Software.
Added in Software under MAME – MAME packages. These are full packages of everything you need to get MAME started except MAME itself (which download from MAME or MESS sites).
TI99/8, 99/2, Tomy Tutor added
also added a standard TI-99/4a setup. this one does not have any documents in it (since a lot of my stuff is Cyc) but has software. In it I have some nice simple .vbs script menus for Infocom games, Adventure games and few others in applications. uses MAME/MESS 20 above like others.
and finally, for today, added P-Card package. NOTE: with p-card package you have to use the MAME dip switch to turn on the p-card the 1st time you use it. (see readme)
May 26, 2020
I would like to thank Steve Willis who sent me a large amount of, nicely commented, software that will assuredly find it’s way onto this website. Well done Steve!

Note on using .DSK files on MAME 99/8 & 99/2.
I have been playing with the MAME 99/8 & 99/2 on MAME. All in all they work fine now. You can’t use the PEB setup but must the Hexbus setup in these machines and with the Hexbus running they are a bit slow on anything less than a i5 machine. The big thing with using .DSK is, even though they look like they might work, they won’t consistently work with Double Density .DSK. Here is Mizapf description of the problem:
Mizapf: I seem to remember one more issue with double density, and I did not have a solution for that. In rare cases, the density detection fails, and the controller assumes FM (single density) instead of MFM (double density). In a debug log I found that some values in double density read like an IDAM in single density.
Trying to explain briefly: The Index Address Mark (IDAM) is a special bit sequence that cannot be produced by normal data, so it can be used to put marks on the track where the sectors start. There seems to be a chance that some MFM data bit sequence looks like an IDAM when incorrectly read in FM. Imagine you hear a music recording at half speed and come to believe you heard “Paul is dead”, and then decide this was the correct speed. So the HX5102 starts with SD, believes to have found an IDAM, and then fails. Normally (what the other controllers do) after the read error, the controller should retry with the other density, and then report I/O error x6 if it fails again, but the HX5102 did not retry. This could be a bug in the HX5102 DSR, but I cannot rule out an emulation issue either.
Long speech, short sense (long story short): Stay with double sided single density (DSSD, 180K, 720 sectors) for now; you can use sector dump, track dump, or HFE, and the image tools like TIdir or TIImageTool won’t do any harm to it.
HLO: I’m conducting more test and will post a full report on MAME/99-8 & 99-2 usage in the future.

Back at it again after waiting for Google to clarify some stuff.
MAME has been updated to version 221.
Here is installation instructions:
0.221 has been published today. Since I already talked about it, no big surprises:
- IDE adapter card working; options for clock chip: RTC65271, BQ4842, BQ4852, BQ4847. Proved to work with Thierry’s IDEAL (65271) and Fred’s IDEDSR.
- PGRAM and PGRAM+ added. Proved to work with P-GRAM Utilities v2.3
You can find release 0.221 on WHTech.
Windows: Run the downloaded archive exe file; don’t get irritated by Microsoft Defender’s warning (More options, run anyway.) Unpack into a folder like “C:\prg\mame”. If you want to run my autoconfiguration script, you need to get and install Cygwin as well (www.cygwin.com). Activate unzip and wget in the Cygwin installer options. The autoconfigure script is named “mameprep_cygwin” and is also available on WHTech at the same location. Put it in your MAME installation folder, open a Cygwin shell, go to the MAME installation folder (cd /cygdrive/c/mame) and run “./mameprep_cygwin”.
Raspbian/Linux: Unpack the tar.gz file in some folder, like ~/mame. It already contains the mameprep script. Go into the mame folder and run it by “./mameprep”.
