http://support.solidexplorer.pl/responses/kit-kat-442-issue
It seems that google changed some behavior related to a REAL external SD card plugged in a device.
Now a non google app can not write on it (so the bug you see)
On My nexus 7 as the 'external SD' is in fact a part of the internal flash, the apps still works.
I don't have any 4.4.2 device with a real sd slot to test. So all you can do is :
1 - root your device to gain back the previous behavior.
2 - see if you can redirect the goxx apps on the 'internal' sd ??
I need to rethink the WHOLE behavior of import/export an a majority of goXX apps.
I am sorry for this problems, but they are related to google decisions ??
I will try to find a new way to do import/export ... DONE
For 1.6.4 release I made the following changes :
On kitkat device, import/export directory is now /Android/data/o2s.emul.hp41cx/files/... instead of /go41cx/... on the sdcard.
You can download modules from Warren Furlow's site (modules and manuals).
then put .MOD file in your 'download' directory on your external storage area in your device.
For a quick test, download the 'MATH.MOD' below then use 'Import modules', then choose a port and choose the module. It must appear in 'CAT 2' function.
If you have difficulties to use this emulator, please tell me which device you have and which resolution is your screen.
If the lcd stay 'blank' and you have an android 4 device, please try to deactivate 'hardware acceleration' for the display (see in your preferences/development on your device).
You can try the go41c to test your device (and screen size).
If you have trouble, try to stop the application from 'parameters/application' adroid menu and restart it.
In last ressort, try to 'remove data' from 'Application management' tool.

New version of skin&overlay files at the bottom of the page.
Just for fun, I use an old PPC program to compute PI (1160 decimals in 15,5h)
Using this program from hepax memory, I just finished 1560 decimals of pi in 22 minutes (max speed on a slow motorola defy) see files PJ.raw for the program, pivalue.png for output of the program and pilist.png for the listing. 1160 decimals takes 13 minutes (and with the printer active...)
