When did it start displaying it? Did you load the new OS update on it? It seems like the OS might be different than what you had... (even if the numbers are the same)

Okay so it looks like everyone has the glitch. Weird though that the emulator has it too because its not even a real emulator.

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)

I did load the new OS to test it and I got a "this OS version is the same as what you have" message.

Did it install it anyway or did it just refuse to start the install? Did you see any progress bar? If so, then it might still have updated it anyway.

So Casio fixed the glitch and then they decided to unfix it for the OS release. Way to go Casio at least this OS is like .1% faster

Well, basically they must have updated the OS but they updated from 01.01.0200.

I added a red text in the first post on front page warning people to not upgrade if they already had 01.02.0200 installed.

11 megabyte installer ??? The OS update it self is probaly no more than a few dozen kilobytes. I hope the installer doesn't use something like rsa keys and extra checksums to update the OS. Also I hope the OS isn't encryted inside the installer. Why can't Casio be like TI and send in a .8xu format. Or to follow the format of other Prizm files .g3x format (if that existed)  :P
Whoa, I didn't think we'd ever say casio should be like TI.  We'll try and crack it.

Should we send CASIO about this bug?

The Prizm flash chip is 32 MB. 16 MB of this can be used by the user? What are the other 16 MB used for? Most likely the OS. 11 MB seems like a realistic size for the OS if 16 MB is available for it. Of course, the OS might be a bit smaller than the PC installer... 9-10 MB, maybe?

Done.

Really? O.O I wonder if the OS really uses all the other 16 MB... I seriously hope the rest of the memory isn't used to store screen data... (that would explain why it's so slow)

Either way if they don't fix the locate glitch or simply cannot replicate it at all or worse: can't figure out what I mean, then I guess bug fixing will be in the community hands or we'll have to wait until someone writes a new language for BASIC programmers.

Since this update doesn't appear to fix the bug, I'll stay with 1.01 if you guys want until there's a glitch fix or a dumping program is created.


Spoiler For Projects:

My projects haven't been worked on in a while, so they're all on hiatus for the time being. I do hope to eventually return to them in some form or another...

Spoiler For Pokemon TI:
Axe port of Pokemon Red/Blue to the 83+/84+ family. On hold.

Spoiler For Nostalgia:
My big personal project, an original RPG about dimensional travel and a few heroes tasked with saving the world.
Coding-wise, on hold, but I am re-working the story.

Spoiler For Finale's Super Insane Tunnel Pack of Doom:
I will be combining Blur and Collision Course into a single gamepack. On hold.

Spoiler For Nostalgia Origins: Sky's Story:
Prequel to Nostalgia. On hold, especially while the story is re-worked.

Based on what I saw in the installer, the OS seems to be about 6 MB, but I'm not sure yet.

But then what would be the remaining 10 MB for? Did they just leave 10 MB unused for future additions or something? ???

Most likely. It wouldn't surprise me if they did.

I guess for now it could be used for some ASM/C programs or a mod could be written that increases the user archive by 10 MB, but then it's not guaranteed to continue working on newer OSes.
