Game Boy Games (and "Portal") on a Graphing Calculator!

[@calc84maniac]

Hey, thanks for featuring my emulator! It definitely shows its limitations on this hardware, but it's kind of crazy that I was able to get it working at all, haha. I also thought I would point out that despite what that review on ticalc says, the emulator does have a save function, but it's only for the cartridge save and not save states like that user was probably expecting.

[@MichaelMJD]

Hey! Thanks so much for clarifying that! I'm pinning this so that people can see

[@karmakrew60]

I just want to let you know that my entire AP Calculus class has your emulator and a handful of roms on our calculators. You're a blessing to us all.

[@itisliamhfjone22]

I was actually about to leave a comment asking why the emulator would make a note about 'not having enough space to save' if saving wasn't possible, but this clears that up. Thanks!

[@James2210]

I looked into the reason why the CE hasn't become the standard yet. TL;DR: It's too powerful. They aren't allowed on tests because they can automatically do calculus.

My favorite piece of software on that site is Fruit Ninja, which emulates the iPhone game surprisingly well by having you swipe your finger across the mass of calculator buttons. It's also one of the few games that actually plays better on a TI-83 Plus than a TI-84 Plus (since the 84 Plus has concave buttons that are harder to swipe over in an uninterrupted motion).

It's pretty incredible to see Game Boy emulation on something that's barely faster than a Game Boy to begin with.

[@ExhaustedWaffle]

It's not even faster 😂

[@toshineon]

@@ExhaustedWaffle Well, the Game Boy has a 4 MHz CPU, the Ti-84 has a 15 MHz CPU. Though the Z80 that's in the Ti-84 is a significantly older design, so that might make the higher clock speed a bit misleading.

[@calc84maniac]

@@ExhaustedWaffle Actually, the CPU is about 3-4x as fast as a Game Boy's, but it has no hardware accelerated graphics so that cuts into the processing time for games quite a bit. And as far as the Game Boy emulator goes, the overhead of emulating a different (though similar) CPU does more than cancel out the extra speed. I considered implementing a JIT recompiler, but these older calculators didn't have enough memory to cache the recompiled code. In the successor emulator on the TI-84+CE, I finally had enough memory for a JIT, which is one reason that emulator runs far better.

[@clebbington]

@@calc84maniacfascinating, thank you for sharing! I've always wondered if this was using emulation for every instruction or if the Z80s were similar enough to only require emulating the graphics

[@calc84maniac]

@@clebbington Right, while they are similar, they're different enough that it's not possible to run the code directly (and even if the Game Boy had a real Z80, it still might not be possible due to not being able to intercept its hardware interactions). But the similarities do allow decreasing the emulation overhead by quite a lot.

Now that I’m fully grown adult, looking back on rules like these really annoys me.

[@myithspa25]

[@xXCaZaManXx]

@@myithspa25 I also had a TI-Nspire (first model) and played pokemon during class. The calculator itself had notepad-esk program among several other programs. I imagine the OP entered in all the answers or entire text books into the calculator. The bottom half of the calculator even detaches, so you can equip different faces with other functions and such. These things were amazing! :D

[@xXCaZaManXx]

@@myithspa25 I also read E-Books on it

[@adorp]

And that's the reason I stick to the Casio FX 82MS. It has all the same functions as a standard Aristo Scholar LL slide rule, but with the added benefit of modern speed, accuracy, and input method. Enough for any science student. I would have picked one of the older HP scientific calculators, but I hate that RPN input method. Figuring out an input mistake is so much simpler on a two line display.

[@apollolux]

When I was using a TI-85 since 7th grade in 1997, I only learned enough TI BASIC to automate stuff like quadratic equations and the Pythagorean theorem. I was never able to properly connect my calculator to my Windows 95 computer at home to do any transfer of anything to or from it, so I never even bothered learning back then that the flavor of assembly that was used was Z80 and would've eventually made Game Boy emulation possible, even at reduced speed.

[@joemck85]

The older ones all the way up through the original TI-89 and 92 needed a special cable that connected from a computer serial port to the little headphone-jack-looking link port on the bottom of the calculator. That port could also transfer files between calculators using a 2.5mm aux cable. It wasn't until later that they started adding a USB port for PC communication in addition to the calculator-to-calculator link port.

[@apollolux]

@@joemck85 Sounds vaguely familiar. I remember having the 2.5mm aux cable because my twin brother also had a TI-85 for his school but I don't remember ever having the serial cable.

[@joemck85]

@@apollolux I had the official serial cable. Apparently there was a chip in that one. There were also some DIY cables you could make just wiring a 2.5mm connector to a serial or parallel plug, but then you could only use 3rd party software with it that supported those cables. Those were how you would transfer games onto the calculator, as well as save your own programs, pictures, data lists, etc. to the computer. For the 85, original 83 and earlier models, this was particularly important since they only had less than 32 KB RAM and no flash "archive" space. If you ran low on RAM, you had to delete stuff to make room. Also it had a little watch battery under a cover in the battery compartment -- this is how your RAM data didn't get erased when you changed the batteries. Later models added a comparatively vast few MB of flash storage that could hold a very large amount of TI-BASIC program code, but that was still pretty easy to fill up if you started downloading games and apps.

[@apollolux]

@@joemck85 By the time I had knowledge, actual programming skills, a better computer to program with, and money to do any the things you mention, I unfortunately no longer had the desire to do any of that with the 85. I also didn't have internet at home back then, so finding all of the info and drivers using school internet and taking it home on floppy disks would've been a massive PITA to my impatient 14-year-old self.

[@T3hBeowulf]

We used TI-82s in HS and my favorite program I wrote for my calculator was a simple program that displayed the "memory cleared" screen. The TI-82 only had upper case characters so I had to draw that screen pixel-by-pixel and display that message in lower-case when the program started. Our math teacher had a rule that calculators needed to be reset before quizes/tests and I had all kinds of other things on mine that I didn't want to erase. She knew it would be hard to fake the reset screen because of the letter case (upper/lower) issue but that little program helped me and a few of the friends in my class avoid reseting every time.

[@steelsofliquid]

I got a Python version before even high school. Unfortunately it doesn't have assembly (and because of complaints from teachers iirc), and I learned the hard way trying to run a port of Bejeweled. But, I did have fun playing BASIC games during Algebra 1, and I do know a fair amount of Python myself, so I could just code some simple Python game if I was bored, or maybe automate some of my work if it's a simple concept for me. TL;DR - As my calculator had Python instead of assembly, it's nice to see what the older models could do.

Out of necessity, I ended up learning how to program my own stuff for my engineering classes. These calcs use a rudimentary form of basic, so you can easily program stuff like vectors, conversions, or whatever. The TI calcs are all a little different between them. So for example, the TI-81's are hard to program for. The TI-83's are a lot more forgiving and the TI-83 plus's have a lot more memory. Ironically, I never tried a game on my calcs. I want to try that Portal game though.

[@clebbington]

My mom was a math teacher. She would have representatives from TI come to teach them on how to use it with their curriculum.

WOW! I got a box with at least 7 calculators bought cheaply from a local online marketplace. People place their stuff their, broken or not. I simply bought calculators with problems, fix them, and they stay with me for nostalgia purposes. It happens I bought a Ti-84 PLUS silver edition. It didn't start with the 4 batteries, So I had to open the Ti-84... much harder than TI-83... and it happens the ground contact was corroded on the board where the metalic piece lands. Fortunately the huge ground contact has ground all around. I just cleaned the corrosion and I also had to clean the rest of corrosion dust. I also soldered a wire from the ground contact on the board to the metallic piece of the negative pole of the battery. Texas instruments had lots of problems with corroded boards but they stupidly continued making them. Ti-nspire has also this problem. The metallic piece reacts with the copper ground/vcc and some calcs simply turn dead and users sell them or throw them to trash/drawer.

[@Markimark151]

I had the TI-83 plus in high school, I really wish the TI-84 came out earlier because I already graduated school when they released those models. But I did download some games like Mario Land to my TI-83 calculator from a peer to peer connector from a friend’s calculator in class! My younger cousin who got the TI-84, she had puzzle games on it. And now there’s color TI-84 CE which are really cool and used for downloading bigger games, but lot of math classes are banning color graphing calculators due to its distractions.

So who here is gonna date themselves and admit they manually entered code from a printout your buddy gave you to a game on one of these (yes, I did back in 1998). You don’t know pain tho until you manually copy code just to get an error afterwards and have to parse through the code to see what you fat fingered. Then you have absolute torture when you manually input a second game just to find you need to delete the first to have enough ram to run the second game. Then once you delete the first for the second, you find out the second game is total crap and regret all your decisions that day.

Portal prelude looks like an homage to portal flash

I love the elevator in the portal
