Tursi Posted October 21, 2013 Share Posted October 21, 2013 I would just note that ColecoVision games can't be trivially ported to the TI.. you have to rewrite all the Z80 code. It /might/ be possible to do some kind of re-compiler (it has been done on other platforms!), but I don't know the Z80 well enough to do it, myself. Mario Bros I'd like to try someday.. it was why I did the Mr Chin test (Mr Chin has no bank switching to worry about). 1 Quote Link to comment Share on other sites More sharing options...
+Gemintronic Posted October 21, 2013 Share Posted October 21, 2013 Instead of ports someone should make a Coleco to TI adapter. Karma is a beeotch 1 Quote Link to comment Share on other sites More sharing options...

You just make everything LOOK so easy! <GRIN> I understand this stuff is difficult, and I really appreciate guys like you that can make all of this happen. Now me, I've had two major catastrophic failures in four days. First, my COM1 port died last Friday on Nano and the second, today my CF card hiccuped about a 1/2 hour ago and I lost everything in my VOLUME 1 (including all my stuff in progress). It's been at least two weeks since I made a backup, and I know better as the Nano is such a flaky device. <SIGH> Well, I don't have time to mess with it either, I have to get ready for work.

Tursi Posted October 21, 2013 Share Posted October 21, 2013 You just make everything LOOK so easy! <GRIN> I understand this stuff is difficult, and I really appreciate guys like you that can make all of this happen. What I did with Mr Chin was easy and not really all that interesting. What Ramus is doing is impressive and difficult. I wrote Mr Chin (and MB) in a cross-platform language, using techniques that I knew would port over to the TI. All I did in Mr Chin's case was replace the functions that talk to the hardware (where I had written code like "HCHAR") with the TI equivalents and recompile. It took one evening to port and a second to track down bugs (some compiler bugs, some differences in the interrupt handler). Mario will be slightly harder due to the bank switching being so different (much smaller banks on the TI, no fixed bank, and it was all done by hand, not automatically). I haven't attempted it yet because troubleshooting compiler bugs during that level of port will be painful, and I'm hoping Insomnia will come back and give us another round of fixes first. Another issue is the cartridge issue... getting GCC code to run strictly from cartridge will be.. interesting. I don't know if I would attempt it at this point.

+Ksarul Posted October 21, 2013 Share Posted October 21, 2013 (edited) Boulder Dash=Rock Runner. The version titled Boulder Dash was for the Mini Memory (making it one of the great reasons to have that cart) and sold by Legio Computing Centre in Holland. Asgard asked the Eric LaFortune if he could port it over to the E/A environment so that they could sell that version in the US. As Chris Bobbitt was worried that the name would cause copyright issues, he also asked Eric to change the name. Eric pops in here now and again, though he hasn't posted in a long while. He's a nice guy that I talked to several times while I was in Europe long ago. Edited October 21, 2013 by Ksarul 1 Quote Link to comment Share on other sites More sharing options...

JamesD Posted October 23, 2013 Share Posted October 23, 2013 The TI-99/4 seems to be missing a lot of the arcade classics. I'm not familiar with all the TI games so some of these might already exist.Does the TI-99/4 have any versions of these that are somewhat true to the arcade?Phoenix, Wizard of Wor, Gorf, Galaxian, Galaga, Missile Command, Rally X (Radar Rat Race), Moon Cresta, Gyruss, Satan's Hollow, Spy Hunter, Joust, Sinistar, Track & FieldSome vector games might be a stretch but... Battle Zone, Asteroids, Asteroids Deluxe, Omega Race, Star Castle, Black Widow, Star Wars, Star Hawk, Tail Gunner Some computer games that might be worth porting:Gremlins, Drol, Wavy Navy, Eastern Front 1941 (last I saw the current port was unfinished), Starship CommandAre there any isometric games on the TI? They tend to be memory hungry so maybe not the best choice but it would be nice to see at least one on the 99. 1 Quote Link to comment Share on other sites More sharing options...

We have versions (faithfulness of conversion to original variable) for Galaxian/Galaga, Missile Command, Asteroids, Zaxxon, Pac Man, Mrs. Pacman, Defender, Pole Position, Boulder Dash, Centipede, Kaboom, Pitfall, Scramble, River Rescue, Frenzy, Dig Dug, Donkey Kong, Jungle Hunt, Moon Patrol, Congo Bongo and I'm likely missing some more. Congo Bongo and Arcturus (Zaxxon) are examples of isometric rendering. Most of these can be found at the tigameshelf.net site. Quote Link to comment Share on other sites More sharing options...
+adamantyr Posted October 23, 2013 Share Posted October 23, 2013 ...Eastern Front 1941 (last I saw the current port was unfinished)... Yeah, that's one of mine. It was one of my first early assembly projects, and the source code is kind of a mess... a big issue is that I really didn't have a great understanding of the A.I. algorithms to be able to re-write them effectively in TMS9900. Chris Crawford (the creator of EF:1941) gave me permission to do the port long ago. And he recently posted ZIP files of fully COMMENTED source for the game and detailed explanations of how the algorithms work. Very helpful!

Adamantyr It's kinda hard to organize your code when you don't really know what the original code is doing. I've blindly ported some poorly commented code between CPUs and after looking at the logic on a different CPU it actually helped figure out and optimize the original code a bit. But I had some familiarity with the target CPUs (6803, 6809 and 6502) and I wasn't dealing with that large of a project. Porting usually involves rewriting a lot of the code once you port it anyway because you see ways to optimize it for the target CPU. Oh yes, I intend to finish it. I do need to start over a bit, though, and make the code base much easier to maintain and work with, offload graphics and other data to files, etc. Adamantyr Good luck! I look forward to seeing a release of that one! Quote Link to comment Share on other sites More sharing options...

I'd like to see an ENHANCED PARSEC running on a 4A with an F18A! Did you see the wizardry Rasmus put into Scramble? Gawd, that guy is gooooood! The colors in the ship, the exhaust, the missiles, the fuel tanks... well you get the idea. An enhanced Parsec would REALLY be POPPIN!!

RXB Posted October 23, 2013 Share Posted October 23, 2013 (edited) I would like to see this on the TI99/4A, I spent 2 years of my life playing it in the bar across the street from my place. Could have bought a car with the money I pumped into that machine. http://www.youtube.com/watch?v=ymrYkbEbnEQ NOTE: It required 2 joysticks as that is how you steer a tank in those days before they adopted the yoke like a Plane design.
