Image converter by Casio?
« on: May 25, 2011, 12:44:03 pm »
When looking at some videos at the Casio Prizm YouTube channel (yes, there is one!), I noticed this one. It's a presentation that shows what the Prizm is, but there's something that they mentioned that we didn't know... Around 7:30, they say that they're going to release an image converter tool soon. This is great news, since it means that we don't have to discover the details of the g3p/g3b formats like we did with g3a, but we don't know how soon "soon" is. Mu guess is that it will be during the summer, to make sure that it's available when school starts again in autumn.

Well, they already have some kind of "app store" here: http://www.casioeducation.com/lesson_library/
And here's something more on the converter: http://www.casioeducation.com/prizm/light_blue

It's only for lessons, right? I don't see what kind of use it has to us.
And here's something more on the converter: http://www.casioeducation.com/prizm/light_blue
That's probably the first time I've seen the word "proprietary" being used by someone when trying to be positive...

Should "proprietary" mean something bad? For me, it is totally okay if a company decides to go the closed source way.
I'm more scared of all this "GPL" code everywhere...

Why do you dislike the GPL? Personally, I don't see any problem with it. Everything that can be done with proprietary can be done with the GPL as far as I know... Except from hiding.

We could make are own image converter pretty easily, but no one has bothered to do so yet. They actually have pretty good compression because g3p has 256 colors with a palate.

List of stuff I need to do before September:
1. Finish the Emulator of the Casio Prizm (in active development)
2. Finish the the SH3 asm IDE/assembler/linker program (in active development)
3. Create a partial Java virtual machine  for the Prizm (not started)
4. Create Axe for the Prizm with an Axe legacy mode (in planning phase)
5. Develop a large set of C and asm libraries for the Prizm (some progress)
6. Create an emulator of the 83+ for the Prizm (not started)
7. Create a well polished game that showcases the ability of the Casio Prizm (not started)

The problem with proprietary software is that often, when it comes to calculators, their quality sucks terribly. Examples:

TI-Connect: Fails to detect your calc for no reason all of a suddent, took until 2010 before it's compatible with 64 bit systems, unnecessary slow (takes about 10 seconds to initiate a transfer)
TI-Graph Link: Crashes all the time, fails to detect the calc half of the time
TI-Flash Debugger/SDK (calc emulator): Slow, 1 keypress detected at a time, slow key detection, doesnt run most ASM and BASIC programs, incompatible with some group files even though it's TI's format.
TI-Nspire computer link software: Takes about 1 minute to startup, even on a quad core computer with 8 GB of RAM
TI-Nspire student software: Same as computer link software, runs about 4x faster than the real calc
Casio Manager: No native file transfer possible, doesn't run at the original calc speed, some features disabled, not even a paid version available, so when the trial expire, you're banned for life from using the software altogether, apparently doesn't emulate all apps perfectly (example: Insight transparency demos)

Another example that isn't for calc is Microsoft Windows. In many cases, a low end computer will be more performant under some recent Linux distros than Windows Vista/7.

TiLP, WabbitEmu and such softwares do not even have those problems. This is why many people are prefer open-source softwares. The only problem with open-source stuff is that it's easier for people to steal the code. Otherwise when those softwares satisfy no one's need, people can take over them to improve them.

In case you are wondering where I went, I left Omni back in 2015 to form CodeWalrus due to various reasons explained back then, but I stopped calc dev in 2016 and am now mostly active on the CW Discord server at https://discord.gg/cuZcfcF

What do you mean by native file transfer?

Well, because of its viral character and complexity. At least version 3 is WAY too restrictive.
Personally, I prefer BSD style: http://www.freebsd.org/doc/en_US.ISO8859-1/articles/bsdl-gpl/article.html

Yeah, the BSD license seems to be pretty nice. It allows the code to be included in programs that aren't open source, which can be both good and bad... I hope those who use it only use it for good. Now that I think about it, what's the worst thing that can happen? Someone sells a paid version of it, but everyone can just get the normal version for free if they want to?

Drag-Dropping g3a files into the emu window is not possible and there is no Send g3a file option in the menus. z80man said it was possible to use our own files in the emu by loading them in the SD card folder or something on your computer prior launching the emu, but the fact is that the emulator itself lacks file transfer options documented and visible to the average user.

Ah ok, for some reasons we thought you were totally against open-source softwares.

Go to Memory from the Main Menu, then press F3. Casio sneaked file transfer into the emulated calc instead of the emu. :)

Casio has actually been offering to convert pictures sent to them into .g3p format. I'm surprised they're changing that.

Although, they're probably not going to like it if we allow any other file formats to be uploaded onto the Prizm.

Yeah the issue is if people start taking photos of their notes then putting them on their calc as images. I know some people do that with cellphones.

Really? I wish they made it more visible X.x.

Too bad, now I can no longer test for life, since my trial expired and Casio decided to not release a paid version of it...

That will save us some work, great, thanks for the info JosJuice.
