To the people who PMed me, I'd like to reply but am too new here to PM people!
I could use your help.
I have lurked on this forum on and off for years and love how helpful and nice the people are here!
Since I now have a MiSTer up and running and some extra boards I'll be more active.
I have three XS sdram boards put together that pass the memory test at 160MHz and two 5.5 IOBoards
with one more to test and will sell the surplus later after I test so other people can enjoy this fine machine.

It's the program, "Barrage". If you're not familiar with it, it is sort of a Missile Command inspired program. I have it as a combined bin cartridge image. I took the image right off of the Ultimate GROM multicart on my TI99.

The program loads and initially works fine, but when the projectiles start coming down, rather than coming from random directions, they are all up against the left side of the screen coming down in single-file, in x=0 fashion, rather than having varying X vector components. It looks like the Y component is fine.

I did a full reset of the DE-10, and it happens that way every time, regardless. The missiles that I'm firing up at the incoming projectiles seem to have normal vectors, and the aiming cursor moves normally.

Finally found some time to look at this. When porting from Speccery's code, I wrote code for the multiply opcode to replace the Xilinx specific one previously used. I neglected to update the delay for this computation to finish before using the result (it's using shifted additions, rather than a built-in multiplier).

TL;DR
It should work in the latest release.

It does work fine now.

I just tried out this new update core with the Ms. Pacman cartridge and still there is no joystick control for this game, the cartridge starts up runs fine, but you are unable to control ms pacman, she just walks to the left and stays there till she gets caught by a ghost (and I dont see any means by keyboard to navigate her).. Just wondering if this still another lingering bug with the core.?

If you reboot the core by doing LCtrl+LAlt+RAlt the boot ROM doesn't reload, but if you do a Reset through the OSD it does reload the boot ROM. Is this something you have time to look into and possibly fix?

Fixed in latest release.

Very nice. Looking forward to the day I can play some Tunnels of Doom on this core :)

That's interesting. Ms. Pacman locks up for me about 2 seconds after the startup music finishes playing.

Maybe it doesn't like something about the cart image I'm using.

Worked fine for me, Played a few levels with no issues. if you want contact me directly.. we can take the conversation offline, I can also give you some md5 sums for my rom images to see if they match.

Hi,

first, many thanks for the TI99 core for MiSTer. It was my first computer, so I really appreciated the port!

I've tested my collection of games with this core (version 2019-02-16) and it seems that most of them are working fine (although I've not tested all of them intensively). I've found some problems with some titles that I would like to report here, to see if this could help with the improvement of the core.
In particular there are problems with the following games:

- Tennis/Micro Tennis (NIceSoft/Databiotics): the ball is moving to the top of the screen at service;
- Tutankham (Parker Brothers): hangs at initial game screen;
- Moon Patrol (Atari): hangs at initial game screen, after the player's selection screen;
- Congo Bongo (Sega Enterprises): the firts level is ok, but the second level is full of garbage and hangs (the same rom is working fine in MAME);
- Miner2049er (Tigervision): the collision with enemies and items are not working. The collision with floor/ramps is working (the same rom is working fine in MAME);
- Mission X (DataEast): hangs at initial game screen, after few seconds;
- Submarine Commander (Thorn EMI): hangs at initial game screen;
- 4A Flyer (Triton): hangs after the initial title screen, in the game screen;
- Return to Pirate's Isle (TI / Adventure International): the game title is full of garbage, then it hangs (the same rom is working fine in MAME);
- Buck Rogers, Planet of Zoom (Sega): hangs at launch;
- U-Boat Jagd (saurus): hangs at launch;
- Mancala (DaTaBioTics): hangs at the game screen;
- Red Baron Flight (DaTaBioTics): hangs at launch;
- River Rescue (Thron EMI): hangs at launch;
- Space Patrol (SunWare): hangs at the game screen;
- Lasso (Texas Instruments): hangs at the game screen;
- Space Bandits (Milton Bradley): garbage on the player's selection screen, than hangs. The rom is the patched version that is working fine in MAME;
- Sewermania (Milton Bradley): same as above;
- Meteor Belt (Milton Bradley): same as above;
- Big Foot Milton Bradley: same as above;
- Super Fly (Milton Bradley): same as above.

I've tested the games above creating the single .bin file and also loading the rom/grom banks. Please, let me if additional details/information are needed.

Hoping to see additional improvements of the core (with speech and disk support...) and bug fixes, again, many thanks for the great work already done!

That is a piece of information I'm also interested in since
I updated my fullRom Python converter script. The new
version can now convert whole directories of files -
the 243 rom cartridges available for the Ti-99 take
only 0.92 seconds to convert to full roms.

This version can be found on Github in a repository
called pyTIrom[1].

Support for diskIO and speech is still missing due to the
lack of respective information.

Meanwhile NML32 put up a video on YouTube demonstrating
a number of combined roms running on the Ti-99 core.
Thanks for the fine work!

Thanks for your help.

Did you find useful information regarding the memory layout of
the disk I/O and speed module on that page?

Please share it with us!

It's fascinating reading about these old computers. This really was a very unusual platform wasn't it! I spent a good hour on your linked site earlier...
