    - 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).

    Sound added, inline help (tap left of display), text overlays working again (use with 'black_o' graphics overlay or 'opt001' skin), ADV printer working (tap right of display), Config with _o.txt overlay files (tap middle of display).

    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.

    The free version states tones are disabled. I thought the were refering to click sounds to confirm when you press a keyboard key. The pay version also does not make any sound on my Samsung Galaxy S7. This is a problem because it leades to errors entering numbers. I can not recomend this 41C emulator. The versions for Apple OS are better.

    I originally had the free Go41C version and decided to update it for two reasons. One, I wanted to be able to enter some programs that I have written for my 41CV. Two, I wanted to be able to use the Math module for solving simultaneous equations. I was able to enter in the programs that I have previously written. This app works exactly like the original calculator in that respect. However, after hours of trying to install the Math Module, I have yet to succeed. I have tried to follow the instructions given online, but there is no import/export function that I can figure out. I have copied the MATH.MOD file to every directory associated with the app, both internally and on the SD card, but the app cannot find it. I sent an email to the developer a few days ago, but have not heard back. I had a similar app on my old iPhone, and it was beautiful. All modules worked, and I could program. I will happily upgrade this to a 5 star rating when and if this bug is corrected.

    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)
