I am sure that it is possible to do a GBA emulator, I know it is hardware wise but maybe getting round the anti hack will be harder. What do you think?
(I am talking about an nspire)
-
Hey Augs - before making new topics, I'd recommend you use that search feature up in the top right. I've found a thread where calc84 (creator of Ti-Boy SE and other emulators for calc) talks about the development process of such an emulator right here:
http://ourl.ca/6307
so maybe you could check that out?
-
Yes, I believe it was said that a GBA emulator would be relatively slow, even for the Nspire. Nevertheless, this would still be great to see!
-
I'm seriously going to make a GBA emulator for the TI-Nspire. Although I'll need to look into ROM file structures, etc. But I'm going to do it anyway...
-
Heya and welcome here Augs. By the way Calc84maniac worked on such emulator back in Early 2010, shortly after releasing gbc4nspire. It was incredibly slow and he lost the files, but then recently he tried making another one and in its early state it seemed to run at better speed, even if slower than the real thing.

You are awesome. I would love to see this!

I hope it happens. I really want one for my nspire. It would be awesome

By the way you can multi-quote posts by clicking quote in one single message, so you don't need to post two messages to quote two different posts ;)
Also annoyingcalc got an alpha build of Calc84maniac's new emu I think :O. However I doubt it's really far into development yet.

Its not perfect yet but Im amazed at how good it is, I like the feature of choosing how many frame are skipped
-
Oh that's nice then. I wonder if he distributes betas/alphas? O.O Also what game does it run?
-
I have wolfenstein 3d pokemon saphire mario world, etc it runs every game I have tried and btw if calc84 approves I could send you a copy of it (only if calc84 says ok)

Good, could It also be for the nspire? Or is it just for 84?
-
? it is for the nspire, the 84 version is available for download(it only runs game boy games), the gba emulator for nspire only works on the nspire cx

Could you please send me it, I have a nspire cx
-
I will have to ask calc84maniac before I can send it to anyone, he wants to release it before next week though
-
annoyingcalc, has he implemented states into the alpha yet?
-
yes
-
Even the equivalent of TiBoy for 84 would be awesome.
Are there any (potential) resolution issues? For me, that was the only thing that made tiboy hard to use to actually play games.
-
agreed with the resulution but no, there arent any resulution problems :D
-
The only resolution problems are that the fullscreen resolution of 320x240 isn't an exact multiple of the original resolution, but the option is included to run at the original 240x160 resolution instead.
As for a release, I still need to fix some issues with save states and make sure that cheats work, and there might be some other things to work out as well. I'd rather not have annoyingcalc's build distributed because it does have some glitches that can crash/reset the calculator.
-
^^ I crash a lot, mainly when im in a game then I switch to another game.
-
Wait really? I need to look into that :P
-
x.x
I wonder what good homebrew games I can find
And also Im waiting for an omni emblem ips patch >.>
-
Yeah if it's unstable it would be best to not distribute the build now, because on a TI-Nspire, an unstable program can actually damage a calculator permanently.

Normally, less so than on a TI-Z80 or TI-68k :)
On the one side, the Nspire has a "reformat entire memory" option in the maintenance menu, unlike the members of the TI-Z80 and TI-68k series. And even if both the boot2 and the diags were erased / invalid on a given Nspire, the serial port support of the boot1 enables transferring proper boot2 and diags, through a fairly common piece of hardware that costs $15-$20. Sure, without a valid boot1, the calculator is toast - but in commercial (production) models, the boot1 is not writable in the first place, without hardware modifications :)
On the other side, several members of the community have TI-Z80 and/or TI-68k calculators that won't boot, and either no known software method can rescue them, or it is known that they cannot be rescued through software. Unless in-place reprogramming of the Flash chip is possible without damaging the calculator's electrical system and the Flash memory, de-soldering and re-soldering the chip is necessary... but then the chip probably won't survive the heat.
-
wait so the emu comes next week? Great! :D
Gotta get my AW2 ready ;D
-
just a question 2 calc84: by cheat, you mean memory editor or like gameshark and stuff?
-
I'm pretty sure they're Action Replay codes.
-
ah, AR codes. :)
Can't wait to have it on my calc ;D

Weird, because often I saw more cases of people with crashed Nspires that didn't seem to want to recover lately than with 83+. Maybe just a coincidence then.
Also annoyingcalc or calc84maniac do you think you could post a screenshot of how the emulator looks like so far?

Dude, that is totally epic. Great work so far! :D
-
Glad you're still working on it—that is one awesome project.

It looks pretty good! I am curious how well it would run on my touchpad nspire though. It has a minimal amount of RAM and that grayscale screen. I think i would rather have it on my CX. :P

Well, as I mentioned in another topic, only the CX is supported anyway (mainly because of the larger RAM). It's also nice to be able to overclock higher.

calc84, load 1 game from another exit that game then load another then CRASH
and its unstable I had to reisntall my os

Awww, this means that I can't try it out on nspire_emu. I don't have a cx, but maybe I can beg my parents for one for Geometry. Preferably a CX CAS.

Seems a bit of a stretch (especially the CAS, since you're usually not supposed to use CAS calculators until past calculus) ::) Good luck though :D

By "exit" do you mean the entire emulator? Or do you mean just load 3 different ROMs in a row.
Also, were you overclocking the AHB? That's the only thing that's ever caused me to lose my OS, I think.
-
Also if Touchpad/Clickpad model support was added, an issue is that most games got a lot of colors so it would be hard to distinguish some stuff in 16 level grayscale mode. Also the screen blurriness would be an even bigger problem than it was on gbc4nspire.
That reminds me, aside from the resolution, I wonder if Doom for the GBA will look better than the Nspire one? I never tried the GBA port.

No I loaded 3 roms in a row (I meant exit the game)
and I have not overclocked my AHB
-
what was AHB again?
-
It's the memory bus, basically.
-
I have no idea what this means, but it officially stands for AMBA High-speed Bus.
-

I tried.
It's much slower, but not as slow as the Prizm port. ;)
The graphics aren't as good because of the inferior GBA screen resolution.
It seems to be less colorfull, but it might be because of the use of different textures.
I've also noticed some physic differences in the 1st level.
-
Ah I see. Do floor and ceilings have textures at all? If not, then maybe it's based on the SNES port. I know also in some ports the camera moves up and down while walking, but in the SNES version, it doesn't. Only the gun moves a bit.
-

Thank you for your report.
I've just updated Nover.
You can still try to overclock as much as you want, but you'll be warned of the danger above 75MHz for the AHB instead of 80MHz.
I should help new overclockers avoiding problems ;)
So best assumed stable config for all TI-Nspire CX is now 222MHz CPU and 75MHz AHB.
You may be able to increase the CPU frequency even more without any stability problem on your handheld. Don't fear anything: you'll just get a reboot if you set it too high.
But you mustn't increase the AHB frequency higher than that, as there is a high probability of corrupting your filesystem, which will cause you more trouble than a simple reboot...

So there are calcs who could go up to 80 and others to 75? I hope in the future TI won't change that so it can only go up to half of that or something... (or stuff like the 84+ extra RAM pages hardware change)
-

Not sure... To my advice, 80 MHz AHB just causes problems, sooner or later.
But there are calcs whose CPU can be set at 240MHz and others at only 222MHz. That's why my CPU warning starts after 222MHz.
-
I thought the max was 150? O.O
-

Not on CX.
Max is 300
-
Lol wow, and what's the default speed? I remember on the regular Nspire it was 90 on older OSes and 120 on newer ones, overclockable to 150. 300 is like more than 3 times the PRIZM max speed (94.3 MHz, for now).
-
300 isn't actually achievable on any CX that we know of, at least not without instantly crashing. That's just the maximum we can attempt to do. Right now I think the default is 132MHz.
-
Oh ok I see. I was starting to wonder if we could emulate the Nintendo 64 now :P
-
That would be totally awesome!
-
I ran project 64 on an old 800 Mhz Pentium 3 based computer yesterday to see how it would perform. It was really slow. The nspire's lack of 3d hardware would make performance probably less than 1 fps. The GBA has like 256k ram and 128k vram AFAIK. Why doesn't the GBA emulator not run on non-cx nspires?
-

He's wondering what takes so much RAM. For one thing, the emulator code is pretty large, and it needs a bit of space for the dynamic recompiler. In addition, the entire GBA ROM needs to be loaded into RAM, which is the main issue.
-
So, any ETA on the release? :D
-

Usually, asking for the release is not a good idea because calc84 is working hard to solve bugs and if he release it now, you would complain afterwards. Also, people begging for the release are often annoying to the coders. Everyone here is waiting for the release and calc84 knows it, no need to put more pression on him ;)
(But yeah, I have to go to a stupid wedding on Saturday, that would be great if the emu was out :P)

Oh, I forgot about the ROM needing to be in ram. And wow, a dynamic recompiler. What kind of speed do you get with overclocking?
-
The speed depends on the game. When overclocking, most games that I've tried run around full speed with a bit of frameskip, though some games aren't fullspeed even with frameskip.

Also if he works too much on this, Runer112 will complain about lack of TI-Boy SE updates and annoyingcalc will become less patient for Project M updates. ;D
As for speed, are there games that becomes so slow that they are unplayable? One worry I had was 007 Nightfire, for example, which seems to have even more advanced graphics than Doom.
Also, will every GBA ROMs fit on a TI-Nspire CX? I don't remember the max size a game can be.
-

Hey, I havent been there in more than a year.
and the max is 32mb and you can zip roms to half their size
-
I was just kidding annoyingcalc. :P Also thanks for the info. :)
Is Zipping supported on Calc84maniac's emu?
-
Is Zipping supported on Calc84maniac's emu?
Yeah. I've actually found that some games that crash on start-up unzipped work fine while zipped.

Don't lose the sources ! ^^
-

Yeah. I've actually found that some games that crash on start-up unzipped work fine while zipped.
You have a copy of the emulator? O_o Also, crashes for non-zipped ROMs sounds like an issue.

This bug happened on the GP2X Wiz version. I can't remember what didn't work, but I think it was Pokemon Emerald. I'm sure others have gotten it to work unzipped, so maybe it's just an issue with my dump.
