Re: Execute buffer overflow by using a corrupted .g1m?

SH-Routines, which call another sub using BSR or JSR, initially push the contents of register PR onto the stack. sts.l pr, @-r15 In most cases the local stack-workspace is reserved after that, f. i. sts.l pr, @-r15 add #-h'58, r15 If any code would erroneously write h'5C bytes to the local workspace...

Yes. You are right, I think. I do not believe, that optlnk can maintain libraries with objects of the same name distinguished by the path only. But to be honest, I never tried such a thing.

I do not think, that you have to support non-consecutive data packets.

Re: LMI(Linear Matrix Inequality) with CP400 - C++ Solver

...I have C++ and C code solver for LMI but i don't understand can I compile and use it in class pad ? The CP 400 does not support addins any more . I do not believe, that it is possible to use any C or C++ source (except perhaps as guideline to develop a program written in the CP 400 built-in prog...

Re: How do I Downgrade from OS 2.09 to 2.04?

I wanted to downgrade for a different reason as my calc won't run most of my games now. Is there a way? The reason for addin-incompatibility often is the MPU. You cannot fix that with OS downgrading. Some time ago, I did downgrading with CASIO update-packages. Instead of following the official inst...

Re: How do I Downgrade from OS 2.09 to 2.04?

The Edit 1.6 problem has been solved here.
In case of this SH-3/SH-4A problem, a downgrade would not have been helpful.

Re: [Bugs]ClassPad II OS Version 02.00.0000.0000

The calculator uses the integration of SQRT(1/(1-X*X)) to calculate arcLen( SQRT(1-X*X)...) . The problem seem to be the integration limits -1 and 1. The expression 1/(1-X*X) is not defined for these values. F. i. if you use -0.999... and 0.999... as integration limits, the calculation is at least p...

I am not sure if I understand your question right. The function key -- role correlation is hard coded for every single dialog.
