[blitz2] displayadjust and 352 screen
hi! i'm thinking on using a screen of 352x224 pixel with my game.
but unfortunately, the adjustdisplay of blitz2 doesn't seem to work with this resolution what i do wrong? here my adjust call (using a fetchmode 0 in the coplist): DisplayAdjust 4,4,-8,8,-16,16 from the bum example this is the correct use for an 336 resolution DisplayAdjust 0,2,-8,0,-16,0 ; 16 pixels added to the left side so from my understanding :fetchwid 4 byte more the usual (44 = 352) ddfstrt -8 16 pixel from the left ddfstop 8 16 pixels to the right diwstrt -16 16 pixelx before diwstop -16 16 pixelx after but i obtain only a (from winuae 3 ) 328 pixels wide screen. why? original image image obtained with adjustdisplay |

From what I understand of the displaywidth command your calculation appears to be correct. Tested on real Amiga it also works - there is however no difference on my screen between the 336 and 352 width - both of them use up the entire width of the monitor (widescreen cropped to 4:3) through scandoubler.
Being from the school of blitz I always thought 336 to be the maximum visible display width anyway, but I guess it depends on more than that and probably monitor specific? |
