| Summary | 02156: naughtyb: Wrong RESNET calculation of the green component. | ||||
| Description |
In MAME 0.61 the color system of Naughty Boy was switched to RESNET calculations and since this version some colors are wrong. The woods are red and not braun (see screenshot 0.60 / 0.127). Compare it also with the arcade shot from the flyer. The flyer shows both screens, in the game it scrolls from down to up. I compared the video drivers from MAME 0.60 and 0.61 and found out that only the green component was calculated wrong. Changed line 95 in mame\video\naughtyb.c from: g = combine_2_weights(gweights, bit0, bit1); to the old 0.60 formel: g = 0x55 * bit0 + 0xaa * bit1; and all colors are matched the original. |
