I wrote a C program for the Casio fx-CG50 but I'm unable to compile it (toolchain issues on Mac M1). Could someone kindly compile it for me and provide the .g3m file?

It's a surface area unit converter (in Italian language) that converts between:

• Square meters (m²)
• Ares (a)
• Hectares (ha)
• Milanese pertiche (pm) - historical Italian unit

With all possible conversions between these units.

• 1 are = 100 m²
• 1 hectare = 10,000 m²
• 1 Milanese pertica = 654.5 m²

• Program name: ConvSup
• Platform: Casio fx-CG50 / fx-CG20
• Required format: .g3m
• Maximum size: 2 MB
• Icon: If possible, a simple 30x19 pixel icon (otherwise default is fine)

Thank you so much in advance to anyone who can help! I really appreciate it.

For the past three months, my friend and I have been playing every available Star Wars game on Casio calculators. We have already launched SW games for Casio FP-1100, FX-702P, FX-7700, FX-9850 compartible, CFX. Lacking original calculators, we had to run games on various emulators.Videos of gameplay can be viewed here.

In 1999, the game called Star Wars Episode 1 was released for the Casio Graph 100. We were able to convert .FXI => .G2M to run it on the official Casio CG-50+ emulator but but failed to extract the images needed to run the game correctly using FX-Interface.

Please help us launch the game! A copy of the file is available here.

[Preface] 

Casio's fx-5800P, which was released in 2006, has been in production for nearly 20 years.This not only reflects the important position of fx-5800P in the fields of engineering and education, but also exposes the gradual decline of the calculator business, especially on engineering.
The fx-5800P was once developed a computer connection cable and program around 2018, which is also a great breakthrough in engineering, but because the calculator connection cable is very expensive and difficult to buy, this upgrade has gradually been forgotten by people. 
Until today, we launched another attack on fx-5800P, successfully found the abnormality of the calculator and completed the functional upgrade.
Important Note: Function upgrade requires the cost of clearing your programs. 
If you want to try, a backup is strongly recommended, such as transferring your programs to another calculator.


[Basical Overflow] 

If you want to let your calculator act abnormally, the first thing is to overflow.The following is the overflow process:
1. [MODE] and enter the PROGRAM mode,then select NEW and create a new formula, I named it OUTTEST
2. In the formula editing interface, press [x^] then press [0] until it is full and you can't input anything more
3. EXIT [MODE] 1 Return to COMP mode, Shift [MODE] (setup), 2 to Adjust lineIO, [fmla] 1 and find the previous formula(OUTTEST), EXE, a "syntax error" appears, EXIT [right] DEL [left] DEL [left], press [0] until it cannot be typed
4. [right] [right] [0] [0] [left] [left] DEL DEL and the overflow is succeeded!
The following are two small exceptions:
1. Lock the machine: (press the p button to recovery)
Replace the second DEL in the fourth step with EXE, EXIT and your calculator is locked.
2. Strange errors: (will be mentioned later)
After the fourth step, EXE, [left], (if you don't change mode through [MODE]) The entire machine will be abnormal, and executing the program will produce some strange errors.
The abnormality may delete your programs!
If this happens, do not use Shift AC/on to shut down and save the progress. 
Just press the p button on the back (thanks to casio's memory protection) and the program will be restored.

Effect : 




[Overflow in TABLE and RECUR] 
Enter a operator which includes a box in TABLE and RECUR's MathIO mode and press EXE to save it into the memory,
ignore the error, EXIT and switch to COMP mode ,then adjust lineIO. Enter TABLE or RECUR again then the box will also appears, 
(you can delete other items and only leave the box. Press EXE twice, and there will be a Syntax Error, the box is saved into memory again, [MODE] 1 to enter COMP, Shift [MODE] and select 1 to adjust MathIO, [MODE] 7 to return to TABLE, and only leave the box there.)
and it can also overflow according to the operations above.



[Character Converter] 

People who have studied other casio calculators must be familiar with character converters. It is based on the conversion between double-byte characters and single-byte characters. 
After our research, fx-5800P also has double-byte characters (the character table is in the attachment), so a character converter naturally came into being.
But this converter only supports double-byte characters conversion to single-byte characters, so we also calls it a 'one-way character converter'. 
The following is the instructions for converting characters:
1. Input the box. There are currently two ways:
i) Under COMP and lineIO (Shift [MODE](setup)2), call a boxed fmla (formula)
ii) In TABLE (MODE7) or RECUR (MODE6) mode. The operations are above.
*you can delete other items and only leave the box
2. Make sure that your box is at the end (that is, there are no characters behind the box)
i) Convert a character:
move the cursor to the front of the box, [right], enter a character you need to convert, [left] 9 DEL DEL, the converted characters will appear behind the box.
ii) Convert two characters:
move the cursor to the front of the box, [right], enter two characters you need to convert (the result will be the second character) , 
[left] [left] DEL [right] [right] DEL DEL [left] [right], 
enter another character you need to convert (the result will be the first character), [left] 9 DEL DEL, then the converted two characters will appear behind the box.
Effect :

*This one-way converter also works on CNX and CNCW (and other Casio calculators?). But the disadvantage is that it can only convert double-byte characters to single-byte characters.
*Characters that can be converted include: # ' & @ [line break], etc., see the comparison table for details:

Currently, according to our findings, symbol ' may be used for comments, while symbols & and ' appear in built-in formula names, symbol ~ appear in fmla trans of self-test.
No use of # has been found yet.



[Functional Upgrade] 

We have been understood the Basic overflow, and the upgrade method is obvious.
In fact, this function upgrade is to enter a fusion mode (not comp mode, but also has the characteristics of comp). 
These functions can be upgraded through the following instructions: 
1. Pull out lowercase letters, Greek letters, subscripts, etc. in the program 
2. Use program commands in Formula
3. Use constants and other instructions in baseN programs
4. Use >, <,≥, ≤, ≠, = in the table to determine whether the conditions (0 and 1) are met
There's an advanced example program by BCX74687:

But please note that these functions come at the cost of your data disappearing.
Therefore, it is recommended to prepare 2 fx-5800Ps and use a spare machine to transfer the "advanced" program to the main machine.
The instructions are as follows: 
1.[MODE] 7(TABLE)Shift [MODE] 1(MthlO)
2.[sqrt] [left] and input "0" as more as you can, then EXE EXE EXIT
3.Shift [MODE] 2(LinelO)[MODE] 1 [MODE] 7
4.DEL [left] DEL [left] [0] [0] [0] [right] [right] [0] [0] [left] [left] DEL(to overflow)DEL EXE EXE EXIT
5.Shift [MODE] 1(MthlO)[MODE] 1 [MODE] 7
6.[+]then input [fraction]as more as you can
7.EXE EXIT
8.[+]then input [fraction]as more as you can
9.EXE EXIT
10.[+] keep inputting [Fraction] and the screen will go blank
11.Once the screen goes blank, input more than 14 numbers and wait for obvious lag
*Steps 1-11 will cause the 'unmapped write'. An alternative way will be mentioned later.
12.[MODE]and enter a mode
13.Shift AC/on(OFF)
14.AC/on to turn on, the calculator automatically resets and deletes all data, but the screen just now will be recovered, and the comp mode will be merged with the mode you just selected.
Notice: Run BaseN programs and switch modes will clear the merged effect.
In step 12,
If you use [MODE] 7 to enter program mode, after turning on,press Shift [MODE] 2 to switch LinelO, 
and then create a new COMP program, 
in the program editing interface, press [FUNCTION] ▼ 1(ALPHA), you can enter lowercase English letters, Greek letters, superscripts, etc. in your program.You can also create a new FMLA or BASE-N program, under the editing interface, [FUNCTION] can enter the function menu that is no different from COMP, and you can use program commands, stat, reg, etc. in your formula or BASE-N program.
If you use [MODE] 5 to enter TABLE mode, similarly, press Shift [MODE] 2 to switch LinelO, 
[FUNCTION] can enter the function menu that is the same as comp, 
3 ▼ can enter the verifying symbol for judging the expression's true or false, 
after the table is generated, if the expression is true, f(X)=1, and if it is not, f(X)=0.
If you use [MODE] 8 to enter EQN mode, under the equation input interface, 
[FUNCTION] can enter the function menu that is the same as MAT, and <Edit Row> and <Edit Column> works normally.
*So, the essence of the eqn input interface may be a mat.



[Supplements] 

In steps 1 to 11, the following instructions also work:
(Please see the original post. Translate of this part is currently not available.)

After abnormal shutdown, the 'set version' of Fmla trans in the self-test will be available, but the calculator will crash when trying to transfer.


Overflow in any inputting interface (except the naming interface) :
Follow the Steps 1-11 above and cause the 'unmapped write'. 
Then input any content in any input box you want to overflow.
Shift AC/on to shut down, then input any content after booting.
Effect:

fx-5800p Single-byte char Table

The one-way character converter

Only just arrived, here so first post. :-)

I've got two 4500Ps and for curiosity decided to see how fast 69! was on each one. 

One was significantly faster than the other, about half the time - both were reset first. Both are made in Japan.

Sorry but this needs a bit of context, hang with me please:

I am working on a sort of mod for my calculator (Casio FX CG-50). I have already managed to develop my own little add-in that is a sort of animation on the screen with user input affecting it, using the PrizmSDK.

Now, the final thing I want to add is to be able to mod my calculator to add a rainbow changing frame using the DrawFrame function. This works flawlessly within my add in using a user timer. The thing with these (user timers) is that they're limited to the child process you're in. Since by entering another app I terminate the old child process (my app) it then automatically deletes it and the RAM my app was using is cleared. Also, exiting to the main menu instantly pauses it.

A way around this is using system timers (I've read the documentation on Wiki Prizm and I know it's dangerous, but I'm ok with it - it's only supposed to be a cool trick to show to my friends). By doing that, if I exit into the main menu the rainbow function continues which I presume to be because the RAM isn't cleared yet and it's a global timer so the handler I have set for the timer is still accessible even though I'm outside the app, which is exactly what I want, and it is quite cool to see (so at least I confirmed it can work until there). If I enter another app, though, it is cleared so I get a system error since that pointer to the function now points nowhere: System Error Address®, and the memory address provided keeps changing in line with how quick I set the timer to update. All system timers do this except 4 which is non-changeable as it's reserved by the OS.

I have tried a lot of things to try and remedy this. One of them was trying to place the pointer in a non volatile spot. While searching through other projects I came across some instances where people did things like:

void backupOCRAM2(void* buffer) {
  memcpy(buffer, (char*)0xE5017000, 8192);
} //This is from an image processing application

(https://github.com/gbl08ma/imageviewer/blob/master/src/imageGUI.cpp#L53)

to write to a non volatile spot for Prizm apps. I suspect that these addresses have changed because trying to change the linker script to include another spot in memory and then adding that to my C code proved to be unsuccessful. On the WikiPrizm (https://prizm.cemetech.net/OS_Information/Processes/) there's information about the addresses for the stack and the heap, but not anything permanent. This is probably too hard and out of my current capabilities but I would greatly appreciate it if anyone who knew anything about system timers and/or non volatile memory locations that would persist even when leaving the app could provide a bit of input. It seems hard, but seeing some other projects doing some stuff such as the code excerpt I provided gives me a bit of hope that such a thing is possible.

Thanks a lot!

My apologies in advance if I made any mistakes posting this.

On the Older 83GT X model (and every CASIO calculator I have used previously) there is a button labelled "x10^" which allows you to enter the exponent for a number using scientific notation. On the newer FX83 CW pressing this button doesn't use scientific notation but just types the characters x10^ into the calculation line and works out the result using BODMAS. (I am using ^ in place of the superscripted exponent).

Here is an example comparing the older model FX83GT X with the latest model FX83GT CW. Both calculators are set to Decimal mode to avoid getting answers as fractions :

The sum I want to do is 25/40k and the correct answer should be 6.25x10^-4.

The key presses for this are 2, 5, ÷,4,0,"x10^",3 and press = for the X model or "EXE" for the CW model to get the answer.

On the older FX83GT X you get the correct answer of 6.25x10^-4

On the newer FX83GT CW you get the incorrect answer 625.

If you actually need to use scientific notation on the CW model you have to force it using brackets which is quite fiddly.

This is a bizarre error for a calculator that is sold by the million and used by many many students in maths and science exams. I would be dlighted if one of you can prove me wrong and find a setting I overlooked to enable scientific input again but I have spent a long time trying to get it work and I have given up.

I am facing a strange problem with my scientific calculator FX-991CW.

I am trying to solve the following: -

((1760*1000*1000²)/69000)/1×10⁴. I tried this in both Math IO mode and Line IO.

I got the answer as 2.550724638×10⁴ in both cases! The answer is supposed to be 255.724638.

This works perfectly in FX-991MS, ES etc but not working in CW.

Am I missing something here?

Thanks a lot in advance!

Vikas J Sheth.

is it possible me to somehow shove conics program into fx-7400gii?

I do have the cable thing and FA-124.

Would it be simple thing, or It would require flashing whole calculator, and installing alternative firmware which has conics.

Thanks,

I wonder if there is any built-in character conversion function,

like character "&" would return value 38.

Though I am aware that casio character set is not ascii, however starting from SPACE till the tilde ~ should be exactly same values as in original ascii.

Maybe I overlooked the manual, but it seems there are not any functions releated to that.

Any info would be appreciated, however I wouldnt write custom conversion program because that might take too much space/storage on little fx 7400GII.

Thanks,
