Yes, it is possible but I won't tell you how to do it.

Google is your friend. When I wanna hack around with something, I research it thoroughly.

I think it's because of the risks that he or the entire Casio community might get (if not already) in legal trouble with Casio if he divulged how to do it. I'm unsure anymore what is the exact reason why that info, which used to be available on other Casio forums, is no longer available anymore, but there's definitively a reason why.

Well, I'm not against hacking... but I'm rejecting any help when someone clearly wants to convert a cheap calculator into a more powerful one. That has turned out to be a bigger issue than we originally had thought.

People have also started to even use very old upgrade tools that are actually unstable development versions. I will never send such files again to anyone. We also heard that a few people bricked their calculators (or were thinking that they bricked it) by using these tools... we are sorry for that, but we can't help when people are even unable to read the manual because they don't understand English... so... sorry, but we really don't care.

Wait, has Casio actually gone after you or the authors of these tools and tutorials? Or did you just stop helping due to the many bricked calcs? I guess both are understandable, though, because the last thing we want are bricked calcs and something similar happened with the PRIZM when overclocking calcs and now people discourage others from overclocking them.

No, but I guess that they know about it.
For instance, they removed a special USB command in OS 2.04 that let's you easily copy the ROM data. They never used this in any PC program, the calculator OS does not use it (unless you request it) and another command for RAM data extraction is still there and fully functional. The only known program that ever used this command is fxRemote... so what does this tell us?
At least they are beginning to remove the easy stuff. They are not actively protecting anything except for their updater software, but I think the main reason has been to not let people misuse their updaters to install modified OSes (this is exactly what we did in 2009).

At least the development versions have a bug that can brick some specific models. How can I know? Well, I bricked one myself...

Hmmm, is it not possible to run a custom C dumper on the calc ? I know that pretty much all TI calc dumps are made via an on calc program.

Hmm I see now. This might explain why the ClassPad II even removes add-in support altogether. The new physium app is actually part of the OS, so Casio probably no longer wants people to use ASM/C on their machines.

I just hope the same won't happen to the PRIZM (considering how few Casio proprietary add-ins there are, I wouldn't be surprised if they had in mind to merge them all into the OS then get rid of add-in support entirely)
