Where can we find how to program sim card's or to make some alterations to sim emu, to make some improvementes.
Sim Emu dont ocuppies every space of 128 cards and the 256 have mauch more space, to improve new features.
Î saw an topic here in the forum but now i couldn't find it again.
The SIM-EMU 5.00 ocuppies all the space of 128 kBit.
The limitation for new improvements is not the EEPROM space but the flash where reside the code necessary for new functions.
Pay attention to the DISCLAIMER.

So you are saing that the card with 16f877 is basecly all used with simemu 5.00 independently if it is 64/128/256; and to improve a new one is need to find another type of card.
So if that is wright, we don't need a card more than 128.
It was possible to "emulate" for each position in flash for ADN more than one, for example:
I have said it one time,
- for each position in the phone have more than one number of phone like in nokia 6210, or in simens s/me45 that for each position we put
telephone number
phone number
e-mail
...
somethink like that.
And for sms more than 40, yes i know that phones only can manage 40, but you may configure two or the blocks of 40 sms,
in sim emu we may select the block that we wat active.
Or one very important question, the phone can white in EPRom, or only on flash??
What you mean with "Pay attention to the DISCLAIMER."?
All the phones read in your own memory, all the phonebook and the SMS's at the startup.
From this moment, all changes in this files are done by the mobile.
Therefore, if a SATK wants to change something of these files, It must require to phone, through a REFRESH, that read again these files, and this is not instantaneous and it does not work ok in all the phones. The REFRESH is used too to change the active line.
The phone directly does not write in Flash neither EEPROM, it "speaks thought GSM commands" to SIM application to tell it that reads or writes files.
The DISTRIBUTION and DISCLAIMER are located in the SIM_EMU_5.00.txt of the SIM_EMU_5.00.ZIP
