|Summary||04403: bouldash: First tilemap is offset by 1 pixel|
Since rewriting the Deco BAC06 tilemap emulation I've noticed that the first tilemap on bouldash is offset horizontally by a single pixel, leaving an unwanted line of pixels along the left edge of the screen, and part of the radar.
This could be fixed with a kludge (simply offsetting that layer for that game) but probably requires more investigation.
a) does this apply to all dec0.c games, or just bouldash?
b) is it the result of an incorrect register hookup (the way different games access some of the control registers was a bit weird so some of the control regs currently act as mirrors, see triothep comment)
c) check it isn't related to the initial state of the protection mapping
d) make sure the real board doesn't do the same (it seems badly programmed in general)

Fixed by Alex Jackson in 0.154. He added SCREEN_RAW_PARAMS to dec0.c:
