i don't know if it is a bug from OpenMSX (version 0.9.1 on Linux, Crunchbang "Jessie" and Lubuntu 13.10 ) emulator - from almost all entries from MSXDEV'13, the keyboard controlled sprites goes to the top left edge, while from http://www.boriel.com/forum/wishlist/download/file.php?id=74 ( http://www.boriel.com/forum/wishlist/started-msx-version-help-needed-as-well-t811-15.html?sid=38308af54375c6fd38fca7b3849b0de9 - a .rom file coded on Boriel's ZX-Basic Compiler ) we can move the sprite to all directions - and the keymap used from snsmat bios routine seems correct ( http://map.grauw.nl/articles/keymatrix.php )

weird is that those very popular Konami games (Nemesis, Majou Densetsu, etc.) are also behaving weirdly, just like MSXDEV'13 entries - i also tried on MESS emulator, which is behaving in the same way...

should i try other emulators on Linux? is this only happening to me? :S

Maybe it's not a problem about keyboard emulation but joystick emulation.
Quick MSX-BASIC test:
10 SCREEN1,,0
20 LOCATE8,13:PRINTSTICK(0);STICK(1);STICK(2)
30 IFNOTSTRIG(0)GOTO20

If no joystick present you should see "... 0 0"

thanks!
from stick(0) it vary between 0 and 8 as expected - stick(1) is always 8, and stick(2) is 0
maybe is there some way to disable joystick somehow? since it is happening on both OpenMSX and MESS, and on both Lubuntu and Crunchbang, i imagine that is some kind of misconfiguration on some Linux config file or something like?

yes, on openmsx, opening the console with f10, and entering "unplug joyporta" does the task! thanks! Smiley
