Sample .C1A add-in for Classpad 330 Plus
Hello Classpaders,
I found an add-in with format .C1A for Classpad 330 Plus. It is available on site Steps in Logic, who sells add-in Algy 2.
This new format has undergone some changes in the header and "footer", when compared to the old format .cpa.
Now it can hold the title in various languages, etc...
Check it!![Smile :)](./images/smilies/icon_e_smile.gif)

I started to read the both cpa and c1a files with HxD. I found some information about this new file type, I'll tell you at the end of my work on this.

You can find the C1A-header and some startup-code (which I use for C1As) here: fx_calculators_SuperH_based.chm (18)
I'll be back!

Really interesting ! So do you think it's possible to modify your mini-SDK for prizm to create add-ins for the CP 330+ ?

Re: Sample .C1A add-in for Classpad 330 Plus
Actually I can use my mini-SDK to create add-ins for the CP330+. But there is not such a fine syscall-interface like with the fx9860- or the fxCG-OSes. Some important OS-functions have to be accessed via absolute addresses. I do not see a future for that kind of programming. It's even worse. It looks like the CP 400 does not support addins any more. ALGY.C2A (the only "addin" for the CP 400 I know) seems to be kinda fake. If you copy a C2A called ALGY.C2A (with proper header of course, but with an empty code range!!!) to the CP 400, the ALGY-icon occurs and surprisingly starts the ALGY-program if invoked! The ALGY-code must be embedded in the CP400-OS. Maybe there is some C3A-option on the CP 400. But that is beyond my current knowledge.louloux wrote:Really interesting !

The C1A and C2A files are exactly the same, it proves that the C2A file is a fake.

Without speaking of a new kind of programming, is it possible, for example, to convert the old games for this new calculator ?

Re: Sample .C1A add-in for Classpad 330 Plus
The CP 330+ is my first classpad. I have no experience with the predecessors. As they switched to the SH7305 with CP 330+, the old CPA PEG SDK is not compatible any more. But what I saw is that the CP 330+ OS still contains the embedded PEG library. If you manage to implement a proper interface (or if CASIO releases a C1A PEG SDK), I believe that you could use old source code.louloux wrote:Without speaking of a new kind of programming, is it possible, for example, to convert the old games for this new calculator ?

Re: Sample .C1A add-in for Classpad 330 Plus
Someone made progress with ClassPad 400?
I bought one last month and this week I found an interesting "error". I edited an Algy2 .xcp Mem Save file and changed in that file, the length byte of the 2nd line of text to a smaller than real size stored in file.
After open it, the calculator displays an error message with the text "Address error". I think it may be a buffer overflow.
Do you think is possible to run code from there?
Note that to save/open files you need a license.
