Emulator

What you describe I could not reproduce on my system. Pressing right while holding other keys worked perfectly fine, and there was no difference for me between 3.5 and 3.5-1593. Are you suuuure it isn't a hardware issue?

Yeah, I've found other users with the same problem on the forum.
Have you tested "A Boy And His Blob" on Dolphin 3.5 with emulated Wiimote?

This is my input configuration (default, emulated wiimote and emulated nunchuck).
A workaround is use the mouse for the nunchuck, (for select right jelly bean) but isn't playabale.
All others beans are selectable.

Dolphin 2.0 crash very often, but the bug is fixed on it!

This is the previous report, fixed apparently only for some revisions and come back on 5xxx svn(source: dolphin forums).

OK, I think I got the answer finally.

First of all, this is more like a "Game Issue", so the Analog Stick Emulation in
Dolphin is just fine (in some sense).
But there is yet a slight behavioral difference on initialization between a keyboard
emulated stick and a true joypad stick.

With a keyboard emulated stick, the center values of X-axis & Y-axis are always 0x80.

But with a true joypad stick (SDL interface), after initialization the center values
of X-axis & Y-axis are both 0x0000 (convert to 8bit 0x80), and once you have touched
the stick, SDL will immediately change the center values of X-axis & Y-axis to 0xFFFF
(convert to 8bit 0x7F).

Unfortunately this wii game "A Boy And His Blob" somehow utilizes this
first-time-touch-transition feature to recognize a true analog stick (dunno if it is
intentional or a game bug), which consequently incapacitates a keyboard emulated
stick. :(

To test or verify it yourself, modify file:

Source/Plugins/Plugin_Wiimote/Src/FillReport.cpp
-- line 973 --------

            if (g_Config.Nunchuck.Type == g_Config.Nunchuck.ANALOG1)
            {
                    //_ext.jx = _Lx;
                    //_ext.jy = _Ly;
                    _ext.jx = (_Lx==0x7F) ? 0x80 : _Lx;
                    _ext.jy = (_Ly==0x7F) ? 0x80 : _Ly;
            }

This will eliminate the first-time-touch feature of a true joypad stick and make it
crippled in game "A Boy And His Blob" (unable to select the jellybean on the right).

Dunno if there is any other game that utilizes this first-time-touch feature ...

With version 2.0, going forward with the levels I ran into problems with key mappings (reverse on select jellybeans, some jellybeans on angle not selectables), also according to the save that I load on the game.

Changing the Nunchuk stick axis from center¶

This problem is solved in the commit "Changing the Nunchuk stick axis from center" that's described in https://github.com/mirror/dolphin-emu/pull/1#issuecomment-21289093

John Peterson, in that link you state:

does "Changing the Nunchuk stick radius" fix http://code.google.com/p/dolphin-emu/issues/detail?id=6427?
No because: it's not related to the stick radius

By your own words, this problem has not been solved. Also, I cannot find any commit with these changes in https://changes.dolphin-emu.org/
