I added a new upload (version 1.62; only the fixed G1A; http://casiopeia.net/forum/downloads.php?view=detail&df_id=154 ). Refer to the original entry http://casiopeia.net/forum/downloads.php?view=detail&df_id=68 for the documentation and other information. Changes made to EDIT.C: I first ins...

The reason seems to be syscall 0x042E, which is not compatible on fx-9860 SH-4 calculators.
Remove the SD-card and try again, please.

I'm still on it.
(I needed some UBC-tools to do that. I had them already coded for fx-9860G/GII SH-3 and fx-CG. Now I had to develop an UBC-tool for fx-9860GII SH-4, which took a bit more time than I expected.)

It works for me in Input/output mode:Linear.
How did you enter Str in Input/output mode:Math?

A few years ago TeamFX told me, the SH7305 is a SH4AL-DSP and that according to bit 29 of the Cache Version Register (0xFF000040), it has no FPU. In these days I made some tests and could not detect a FPU. Here you have a complete list of all SH7305 registers. All SH7724 registers/modules, which you...

There are some more syscalls (0x0C61..0x0C6A). Especially 0x0C61, which is a 9-parameter call.
I did not unravel all of these yet. I hope to gather some usable results during the week.

This is, what I know: SysCall 0x0C66: int SaveFileDialog( unsigned short*FileName, int mode ); FileNameBufferLength at least 0x214 (t. i. 0x10A unsigned short items). mode == 4 If EXIT or QUIT has been hit, the keycode for EXIT ist returned (0x7532). In this case the buffer contains "\\fls0\&qu...

I will try to follow the EDIT 1.6 error. It is interesting. --- But first, I noticed another intriguing thing, while searching for the EDIT 1.6 problem. On fx-9860 calculators, there exists a 32 KiB RAM range (physically 8801C000-88024000), which is used for stack and addin static RAM. The stack sta...

I checked it with a fx-9750GII SH-4 (OS 2.02.0201): successful. And with a fx-9860GII SD SH-3 (OS 2.00.0200): successful. And with a fx-9860GII SD SH-4 (OS 2.09.0201): System ERROR. Since OS version 2.00 they ceased to support certain syscalls. http://casiopeia.net/forum/viewtopic.php?f=11&t=174...

If I remember well, TeamFX once tried to gather a complete list. I contributed a few: fx-7400GII (2009.0327.1515): HardwareIdentifier: Gy362000 ProcessorIdentifier: RENESAS SH735501 PreprogrammedROMcapacity: FlashROMcapacity: RAMcapacity: PreprogrammedROMversion: Bootcodeversion: 02.00.0000 ...
