- lib#4 from A. Martin support
- lcd lowercase display (roms are patched)
- all import/export now use '/go41cx/...' directory instead of '/Download' on your sdcard (usually '/mnt/sdcard/'), export again all your files to recreate it.
- haptic feedback added (activate it in your device).
- short manual to explain all the behaviour (see at http://sites.google.com/site/olivier2smet2/home/go41cx ).
- new basic skin (like the first release).
- some interface changes (new really hard reset).
- partial card reader support (only hp67 emulation functions, no hardware, see http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv006.cgi?read=10774)
v1.4.0 upgrade: change of state file format, EXPORT your raws and xmem before upgrade if possible (MEMORY LOST at start).

Full HP 41 CX/CV emulator:

- Full memory and X memory.

- Timer functionnal, but accuracy not well tested (AF is not emulated).

- Manage states, overlays, raw prgms, xmem, ...

- Automatic save and load of state.

- Download modules, raws, from internet, then use 'import'.

- Use MOD modules, RAW programs format.

- You can put modules, raws, overlays, xmems, states in 'Download' directory of your SD card.

- 'ON' only active on 'longtouch' to avoid mistakes.

- Master clear supported (use 'press back' menu when calculator is off then press 'ON', then press 'back' to release it).

- Speed greater than 1 are not patched for 'PAUSE' ...

- Hepax support up to 4 * 8KW modules

- Top status line for Stack, Alpha ... display (tap on it to change it).

Avoid checking 'force gpu rendering' in developer option in android 4.x prefs, this leads to graphic problems.

Emulator loosely based on Non-Pareil from Eric Smith, font by Luiz C. Vieira.

A nearly perfect copy -- but... Before the "but" I must say, buy the cx version. $9.00 is a deal. I paid $300+ for my 41cx in 1984 and used it every day for years. I loved everything about it, except the 14 segment LCD. With only 6.4KB RAM and no GPU it was a necessary compromise 35yrs ago but it's a crappy font. Today this sits on my phone -- 2GB RAM, quad-core CPU & GPU. Nostalgia is fine, but I would like the option of taking advantage of my 1080 x 1920 display by using the most readable font possible. Nexus 5. 4.4.4

Works just like my hp41CX This is a great calculator. It seems to work perfectly on both my Droid Mini phone and on my Nexus7 (gen 2). Bravo! Now if it just had a PPC ROM plugged in like my HP... wait, that *may* be possible.

GREAT PROGRAM! It's like a HP41CX on Steroids. I've been a HP41C user since 1979 and this is by far the best emulator of it. It runs great on my Samsung Galaxy Note 2. (Running Android 4.1.2)
