セット詳細
 
概 要カクテルモードで、プレイヤー2のスプライトクリッピングが正しくない。
詳 細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.

See bug2074 for some snaps.

Specific examples: froigger, mooncrst, pacmanbl
As explained in notes below.
再現手順Play 2-player cocktail mode.
When player 2 comes on, look carefully at the top and bottom.
追加情報This "fix" works, but is it acceptable?

in video\galaxian.c

in "sprites_draw" function: (old code crossed out)

// clip.min_x = MAX(clip.min_x, galaxian_sprite_clip_start * GALAXIAN_XSCALE);
// 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;
	}
