This is by Calc84maniac, obviously. He sent me a copy so I can film it yesterday. The ROM image was a regular 83+ one, including a few programs.
Could this be a replacment to the regular Nspire built-in 84+ emu that doesn't support undocumented instructions?
-
It is me or the emulator runs way too fast compared to a real TI-83/84?
-
yeah it's cuz he removed speed restriction. He asked me first if he should removed it and I told him to, to show the full emulator potential. Desolate ran much slower, though.
EDIT: QUOTED FROM CALC84 on IRC!
[00:51:55] <calc84> oh, and btw, the TI-83+ emulator was running at 90MHz :)
[00:52:09] <calc84> so it could go even faster at 150MHz
:o
-
WOW, this looks great. With all these new NSpire programs coming out I may have to go out and get one.
(also I noticed the video time was 314 :P)
-
Awesome! I see it supports the 84 keypad too. Will it have save states and all the other goodies one would expect in an emulator?
-
My 'awesomeness by calc84maniac'-sensor is going nuts again.
Kudos! Let's get rid of this crappy emulator by TI!
-
Wow, when it gets stable I will have a nice TI-84+SE emulator in my CAS!
Awesome speed. :o
-
I personally hope it will run TI-Boy SE, RealSound, omnicalc virtual functions, etc. Well I know there's a GBC emu for Nspire alerady but it would still be cool if it ran, as it would show what the emu is capable of compared to TI emu :P
-
We all do.
I wish you could show some TI-BASIC game in fast paced version. :)
-
This will be great!
Wait, if this is only at 90mhz, then what's 150? ;D
Calc84, when this is done, will we be able to send files to it through the link port from a 83+?
-

It would probably have this feature already, except I haven't figured out how to activate the I/O port on the 84+ keypad.
-
I wonder if with speed restriction enabled the CPU will be clocked way down or if you are just gonna add some delays? I think the former may save a lot on battery life
-
Nspire really has a problem with batteries.
Battery saving options will be a must for some programs like the calcmaniacs' emulators.
I hope there is a way to the CPU enter a battery saving mode while delaying.

I believe I already do this with gbc4nspire... I am not sure how much effect it actually has on the battery life though.

Does the emulator only support 512K ROMs ?
-
Ok, I've made some tests with 20 TI-83+ 512K ROMs:
- the 10 OS I've got (1.03, 1.10, 1.12, 1.13, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19)
- combined with the 2 Boot Codes I've got (1.00, 1.01)
In all cases, the emulator is booting correctly.
So congratulations for the compatibility!
I also tried to use some very similar TI-73 512K ROMs, but it hasn't worked up to now.
-

I'm happy to hear that.
Btw: Anyone deleted my post? That was not meant to sound sarcastic...
Seriously, this adds much more value to all 83+/84+ Projects(!)
-
nice to hear it boots fine critor!
@lolje, nope, none of your posts were deleted, because I checked the trash bin forum (invisible to everyone but admins) and I saw none of your post there. Unless Eeems did it but it's less likely because he knows I don't want posts to be deleted (except adult/warez stuff)
-
Any new progress on this? Maybe a alpha release?
I wonder whether TI likes this or not.
-
Mhmm idk if they will take any action if we do not redistribute the ROM images. I think Calc84maniac is planning to do what WabbitEmu, Em8x and VTI authors did: require the user to get a ROM himself to emulate the calc.
I am curious about progress too, altough I think Calc84 is busy with the Mario game for the 84+ ATM.
-
Maybe if he uses benjamin's 3rd party boot code for z80 calcs and just send a upgrade file downloaded from education.ti. Hmm, I don't know if this actually works, I am not an expert.
-
Hey, calc84maniac, when you say you can't figure out how to write to the nspire's link port, what do you mean? is it a problem with the addressing, or is it more complex? Hackspire has the memory location of the 84 link port listed.
-
If I remember, even BrandonW and other people like ExtendeD haven't figured out either.
/me wonders if that stuff is possible to access through Ndless
-
I was wondering that myself. Maybe someday we'll have Ztetris for Nspire and be able to link it with any other TI calc. =)

This is true. However, writing to the port does not appear to have any affect on the link cord lines. I assume it must need to be activated somehow.
-
calc84, can I have a copy of this please?
Email is [email protected]
damn nspire ti-84 keypad suxs
-
I wonder how much use it would have if you cannot link the calc, though. (assuming you are requesting a copy of the z80 emu for the TI-Nspire)
-
Oh, really? I wouldnt know.
-
Another concern I have is if the speed is not 100% accurate (example, if it's 99.999% accurate), would linking with a real 83+/84+ or a computer fail, anyway?
-
There's generally a small amount of tolerance, and at least TiLP will allow you to configure values. If it's too far off, though, other calculators and TI-Connect probably won't be able to handle it.
(Btw, 99.999% is a deviation of only ~60Hz on an 83+, which is very normal and can be created by simply using older/newer batteries)
-
Yeah my main concern is when sending to a real calc or TI-Connect. Of course people could switch to TiLP but not everyone can get it to work, especially those with 64-bit OSes
-
I got it to work, press f8, but that DOES get annoying, so I use a 3rd party signer
-
3rd party signer? You can sign your own drivers? I think the development team will want a link. ;D
-
Providing it's safe, though.
-
TI's own 84+ emu's speed is so inaccurate that most programs/games that need to connect to another calc fail. :(
-
Yeah I noticed with OS 1.6 and 7. It was not as bad with 2.0/2.0.1 but I had it happen sometimes. Btw I am talking about outside games. I can't imagine how bad it must be if you play Ztris, for example...
-
Yes, it can, problem is that the signature is gone when you try to change from silverlink to any other cable. I dont know why.
-
Does this require ndless to run because sadly i have the new touch pad system and have been out of luck on many things?
-
Yes, this will require Ndless to run if it is released.
-
If using the real link port isn't working out, then at least make a release that has a virtual link port, where the emulator can send .8x* files already on the calc.

Calc84's computer crashed the other day, and he lost the source code for this, along with several other, projects. I doubt we will see a release of this soon. :(
-
That sucks. :(
-
Yeah I saw in the logs. I was really disappointed :(
I hope he won't give up on his projects and that he at least could recover some stuff.
-
Oh, man, that sucks... I wish calc84 good luck ;.;
-
@gkaee
Don't fret too much. Ndless will come out for up to 2.0 (2.1?) eventually!
-
Necropost time!
Just wanted to let you all know that I've been working on a new z80 emulation core to replace the lost one, and it's chugging along. None of it has been tested yet, so I'll probably have bugs to work out once I finish implementing all opcodes. (And no TI-specific code has been written yet)
-
Lol, that was a giant necropost!
Glad to see progress! :w00t:
^^I use that smiley too much nowadaays :P
-
Hurray, progress! :D
Keep up the good work! :)
-
Yay! This shall be glorious.
-
Great :)
Do you have an ETA for a public beta, complete with source, like Mrakoplaz did for nDoom ? ;)
-
Resurrection! It's good to hear it.
-
Ah very good to hear! It'll be nice if we get a better 83+ series emulator running on the Nspire. =)
-
Awesome! I'm glad this is revived! Please backup this time, though. :P
A few people have asked before if there was such emulator available and I pointed them to this project, but the project was inactive. This shall make people happy, especially those who want to play games that won't work on TI's emu.
-
Yes, and maybe send out some source files to trusted people, just in case...
-
epic, pure epic. Necropost EXCUSED!

Agreed.

How's this coming? I'm hoping for another one of your necros ;)

Same here, although I am curious what he has been up to lately. Maybe he jumped back to another project.
