HP 49G+ 50G emulator for android.

YOU NEED TO LOAD THE ROM FROM INTERNET TO FULLY USE THIS CALCULATOR, see later in the description how to do that.

- Full memory, port 0, 1 and 2.
- ROM 2.15 support (you have to download it yourself, see explanations)
- Automatic save and load of state (ram and flash).
- HP49G+ like skin or HP50G like skin.
- Landscape or Portrait mode.
- Multi touch keyboard support, permits 'shift' down while pressing another key (ON+C, even ON&UP ... are ok).
- Load/save to/from stack level 1 support (only object in IRAM).
- Speed from x1 upto x10 (max depend on your android device.
- HP82240 compatable printer as serial printer (touch right part of calc lcd) (in PRTPAR, set length of line as 23 or 24 characters, default is 80 producing bad formatting).
- Flags help, full commands help (I hope so) (touch left part of calc lcd).
- Clock synced with android time (Timers emulated, clock and ticks are ok).
- Smooth hardware scrolling emulated.
- Should work with at least 800x480 screen.
- BEEP command support (keyclick is not well emulated). (broken on android 4.3 see http://code.google.com/p/android/issues/detail?id=58113)

To load the rom:
1 - Download a rom upgrade (i.e : HpCalc.org, entry named ROM2.15, use Google with "hp4950v215.zip", the official HP name for the file upgrade).
2 - Extract the file named 2MB_215f.bin (from 2MB_FIX.zip) if want to have the full installation (with eqlib and all).
3 - Extract the file named 4950_215.bin if you want only the rom (flash port 2 empty).
4 - Put this file in the 'download' directory of your device (to be sure, you can send the file to yourself by mail and download the .bin from your mail app on your android device).
5 - Start the app, a rom should be loaded and the calc should ask you to "recover memory". Respond NO with F6 key.
6 - Otherwise a black lcd screen means that the rom was not found, use 'about' in 'menu' to see if you got a rom or not.
7 - Don't try other roms as the rom is patched at the first load.

To load a file:
1 - the first time, do "menu", "tool", "load on stack", and abort, this will create the right directories
2 - then download (from http://www.hpcalc.org/ for example) the raw file you want to load and put it in 'sdcard/go49gp/files' with a file manager (i.e. Linda manager or Ghost commander)
3 - on kitkat device import/export is now at /Android/data/o2s.emul.hp49gp/files instead of /go49gp
3 - next do "menu", "tool", "load on stack" your file should appear, choose it
4 - as told by the pop up, now press 'ON' key to refresh stack display
5 - et voilà, your file is loaded on the stack, now do what you want with it
6 - if you don't know what to do with it, get and read an HP49 manual !

Actually:

- no arm support
- no hp sd card support
- no grayscale support.
- serial only as printer.

Avoid checking 'force gpu rendering' in developer option in android 4.x prefs, this leads to graphic problems.
On S5 devices, long press the right hardware button to get the menu.

Keeps jumping off into the weeds The emulator design isn't the problem. Good work on that, Oli! But any time my finger touches outside a button, even slightly, the screen stops refreshing and nothing after that helps... it's just NOT USABLE, practically. Here is a good way to reproduce the error: type the expression 100! (In RPN mode), then down arrow to edit, then right-arrow to see the whole number. You'll NEVER make it to the other side! Say bye-bye!!

Works okay, but too expensive. The application works okay (if you avoid any of the "reset" actions in the menu, which invariably crash it beyond recovery). It sure feels like the real calculator. The UI matches that of the calculator, but doesn't improve on it. This feels kind of silly, because the app running on a modern phone could be far more convenient to use than the calculator itself. There is no meaningful support for phones with a slide-out keyboard either. So you get exactly what was advertised -- an emulation of the HP49g+ --

Great, but... Please turn off haptic feedback and update the skin to high resolution. I have haptic feedback disabled on my phone yet the calculator keeps buzzing. It appears that the latest upstate may have fixed the key up/down issues, but the random lockup seems to happen when the clock is enabled under display settings.

Timing issues and expensive You'd think that for 14 bucks you'd get a high resolution skin, but no. Plus, there are key timing issues. Droid 48 is free and has no issues.
