Is it possible to turn the TI-84+ CE .8eu OS file from education.ti.com into a ROM? #247

Closed i336 closed 6 years ago

i336 commented 6 years ago

I don't have a TI-84+ CE, and would like to see what one is like to work with. I want to randomly poke at/play with CEmu in TI-84+CE mode for 10 minutes :)

Well. Either my Google-fu is really bad today, or the, uh, droids I'm looking for *AHEM* don't surface easily. That doesn't surprise me that much, really; 2015 was only 3 years ago after all.

However, in the process of poking around, what I did find was this no-fuss OS download from TI. I had no problems accepting the attached EULA, and now I have an .8eu file.

While searching I also stumbled on this small guide showing how to JPEGify a calculator ROM awesome. to load it into jsTIfied, where I learned Wabbitemu could convert downloaded OS files into a ROMs.

Except, of course, Wabbitemu doesn't support the TI-84+ CE. Understandable.

(Must-mention sidenote: I initially tried https://github.com/alberthdev/wxwabbitemu, which compiled and worked perfectly(!), minus not supporting the TI-84+ CE - and then Wabbitemu via WINE.)

So, I'm curious - have I not searched deeply enough, or is this currently not possible? Is the reason it's not possible because this OS download is missing necessary info baked into actual ROMs, perhaps?

Indeed, not possible...

... because of that, yes. Dumping the ROM from a CE also gets the boot code, which is something both needed and not available anywhere than on your calc (sharing ROMs is basically illegal, and TI has rightfully shut down some websites doing that).

would like to see what one is like to work with.

If you just want to explore the CE, you can take a look at TI's Smartview CE (it's free/demo for like 30 days IIRC). It's not very good emulation-wise for developers who want hardware-like accuracy, but it's good enough for teachers, for instance, that need the calc software to work like the physical device, at least.

Also, yeah, CEmu is the only third-party TI CE calculator emulator, so don't really bother looking for another one :)
