Size of 256 is not required. You've just selected incorrect keymask,
that's why you have so big values. Look through your values, in the
upper 4 bits only two bits are used - 0x80 and 0x10. So you should
probably use mask_keycode with 0x47800000 instead of mask_keycode =
0x7f80000. Or even smaller mask. Include only bits which change the
values, nothing more.
