20 hours ago, Vorticon said:If you build it, they will come
And again, the Adam is a very different animal from the game console, so frankly lumping the 2 together is not helpful and vaguely condescending...
Are you the Colecovision moderator?
Vorticon,
perhaps it's worth checking out the new Atariage "clubs" functionality which are basically mini-forums you can setup yourself if I understand correctly.
It's kinda silly being at the mercy of a moderator. You won't know if a new subforum takes of unless you try it. Just my 2 cents.....
Myself I'm very interested in The Adam Computer lately and reading about development stuff for it (which is not the same as game development)
I especially enjoyed reading about the CPM text editor you implemented.
Now thinking about it, could see a subforum for TI-99/4a related computers like Tomy Tutor & Geneve 9640.🙂

Yes, progress is slowly but steady. 😀

Watched the video. Very impressive like it a lot!

This is a very interesting thread.
Guess cross-sharing ideas can't hurt; in the Colecovision section there is some VDP stuff being discussed and worked on as well:

If you downloaded ISABELLA4, you should replace it with the new version in post 1 or post 667. When I posted earlier, I did not include the licensing agreement for Asm994a which Burrsoft says must be included.
senior_falcon you might consider switching to Ralphs' xas99 ?
-
I think this is the best TI-99/4a game ever, seriously.

Reminder for myself that I need to add:
- New MG Explorer cartridge image
- TIPI hardware/software reference

Thanks for posting the pics and showcasing the TI and Dragons Lair. Always get a kick out of seeing TI-99/4a Pitfall! at a gaming convention. Like the Atari joystick too. Wish I could have been there.

I have added a sound when you cross the finish line. And since I compressed the sprite patterns I now have 200 bytes left.

I like it a lot. Thanks for adding!

Dont know if you have still any space left, but would be cool if you do some sound effect when crossing the checker flags at the end of a level.

No facebook for me my friends.
I registered about a year ago and left a few days later.
Was constantly nagging me with notifications and what not.
Guess facebook is what you make of it, can be good or bad.

Why is there a Z80 on the triple tech card? What is the Z80 used for?

Dont forget Pitfall!
Plays nice on a unexpanded console, at least if you have the cartridge version.

I have played this game on my Tutor and I didnt see anything that cant be done on the Ti-99/4a.
Pretty sure you could convert the source code to Ti-99/4a with small modifications (unless door door would be running
a z80 emulator, you never know) or perhaps even start from a ROM disassembly. Just my 2 cents.
Wont be me though, too much on my plate.

Reminder that the linked document "ti hardware compendium myarc info.txt" should be added to the development resources thread. Very valuable.

Myarc128/512K CRU paging information is in the first section.
This hardware compendium might be a valuable reference doc to add to one of the pinned posts.

Nice! I will add it to the development thread. Thank you! :-)

My - currently in development- programmers editor TiVi is designed for using SAMS. See the programming subsection for details.

Wow impressive! Do not want to sidetrack, but what would it take to make a tomy tutor version of the keyboard?

Finally had a chance to look through my files. There were snippets of MiniWriter source but nowhere near complete.
I did find source to Sorgan, Desktop Publisher, 4ATalk (Qtem), and a few others. I don't know if anyone is around to OK their release; I came across them from another TI'er long, long ago. Anyone have thoughts on this?
To be honest, I am for releasing all source code so that it can be preserved for history, more than anything else really.
This is for a system that is now 40 years old. Tend to agree that for new homebrew software for the Ti-99/4a it is up to the author to decide how to deal with it.

Force Command ver 1.18 : kinda like command.com from 1985 (no TIPI required!)
in TI-99/4A Development
Posted
I would be interested in a specification so that I can call my own binaries and safely return to force command. Is something like that planned?
