| Summary | 02077: Some set in galdrvr.c: Sprite cut-off isn't correct for player 2 (cocktail mode) | ||||
| Description |
The sprite "rectangle" doesn't turn around when the screen is flipped. This leads to sprites being cut off near the bottom of the screen when player 2 is playing. Quite noticeable with Moon Cresta, and slightly less so with Galaxian. With Moon Cresta, unwanted sprites can sit on top of the scores. Specific examples: froigger, mooncrst, pacmanbl As explained in notes below. |
||||
| Steps To Reproduce |
Play 2-player cocktail mode. When player 2 comes on, look carefully at the top and bottom. |
||||
| Additional Information |
This "fix" works, but is it acceptable? in video\galaxian.c in "sprites_draw" function: (old code crossed out) // clip.max_x = MIN(clip.max_x, (galaxian_sprite_clip_end + 1) * GALAXIAN_XSCALE - 1);
if (flipscreen_x)
{
clip.max_x = (256 - galaxian_sprite_clip_start) * GALAXIAN_XSCALE;
clip.min_x = (256 - galaxian_sprite_clip_end - 1) * GALAXIAN_XSCALE + 1;
}
else
{
clip.min_x = galaxian_sprite_clip_start * GALAXIAN_XSCALE;
clip.max_x = (galaxian_sprite_clip_end + 1) * GALAXIAN_XSCALE - 1;
}

When I tried the other bug related 02074, reporting the 1st player having sprite offset, I noticed this in the example game, but the 2nd player (to me) looked fine. You are referencing this bug from snaps from the 1st player offset? I'm confused. I encourage others to try the galdrvr.c games and report as to offsets they notice and what sets show it. |

I tested galaxian, uniwars and frogger. Everything looks fine in P2 cocktail mode here. |

Try pacmanbl, see on the snap, at the top the yellow monster has a part cut off. In Frogger, it only shows if you jump away from the road and onto the time bar. For player 2, the frog disappears. The best check is with mooncrst. |
