Official TI-Boy CSE Alpha Thread

Oh. You'd think that they would've had some sort of relay device that expedites the screen drawing considering the disparity there. I personally figured there was a draw buffer that was accessed by bankswitching then pushed to the screen. I'm not an engineer yet, so I don't even know if that'd be the most efficient. That's too bad though, I'd hoped the problem was software side. To me it seems odd to run a 16-bit device with an 8-bit processor though.

Apart from the CE, no calculator of the TI-84+ line or lower has had memory mapping, which is pretty much what you just described. And even then, the rest of the hardware is simply ancient. There's only so much you can do with a 15MHz processor where even the fastest instruction requires 4 clock cycles to complete, and to trying to drive 75K 16-bit color pixels with that is just not going to work very well, even with memory-mapping.

And why 16-bit? TI wanted a color calculator to deal with some of their competition, and that's what they could come up with without radically changing the basics of how the calculator is programmed (since their OS still has to run with little modification).

Even though you don't need a supercomputer to do basic addition and multiplication, you still need some minimum specs to make the whole thing work. From what I understood, too many people complained about the CSE's slowness, and so TI responded some time later by releasing the CE, which ran significantly faster due to its use of an ez80 processor with having memory-mapped (almost) everything.

Do remember that these devices were never meant to be used to play games, and so were never built with that capability in mind. The fact that it's possible at all is a testament to the programming community as a whole. I find it nothing short of a miracle that TI-Boy will run with any kind of speed on the CSE.

I don't have the SCE, so I practically ignored this thread, but I might get be getting a CE soon, so I was thinking, would a CE port be possible?

[TIfanx1999]

Well, yea. I think we will have one eventually. As to when, hard to say.

[Eeems]

It would require calc84maniac or whoever else has the source getting a CE and taking the time to port it. I'd love to take a stab at it, but I've got another project I'm porting atm.

Bug report: Most rom patches don't work, like Pokemon Brown. They function correctly, but it takes forever to load.

So they don't work or they take forever to load?

Like, the screen goes black and I left my calculator on for 3 days and it never loaded the battle screen.

I'm new to this entire forum and was planning on downloading Pokemon Silver to my TI-84 plus C Silver Edition but when I opened TI Connect to try to add the Emulator (I had the ROM file directory and such inputed  TI Connect insisted that the file was an "Incompatible Type". Am I missing something obvious/simple?

You cannot simply copy over the ROM to the calculator, you will need to convert it to a calculator-compatible format with the tools provided in the download of TI-Boy CSE

^This. It's probably in the readme file. Highly recommended reading.

Is there any potential of this ruining the calculator?

Which ROM did you guys use? I tried different GBA and GBC ROMS from different websites, and every single one doesn't work can someone suggest a ROM website to use? Many thanks

As the first post and the readme both mention, this emulator supports only original Game Boy games. Game Boy Color and Game Boy Advance games are not supported (and due to significantly higher emulation requirements and the fact that this project and calculator model is mostly dead, likely never will be).

A suggestion of a my two favorite original Game Boy games that should work: Pokemon Red/Blue (maybe Yellow?) and Link's Awakening (not DX).

@Runer112 thx so much i didn't realize I downloaded gba games
