added a new option for entrances to have Mario face the left direction.

To have H/V scroll set to None, you should be using the 4th entry in the list rather than one of the later ones. Note that these take up slots that were previously blank (H/V Scroll of None), so you may want to double check your scroll settings in older levels.

added 4 new vertical scroll settings for layer 2 (Variable 2, Variable 3, Variable 4, and Slow 2).

The BG height is a new setting in the 'Change Other Properties' dialog, along with an option to just set the BG relative only to the FG which is meant mainly for layer 2 levels.

added an option for entrances to use a new FG/BG init system which can set the FG relative to the player, and calculates the BG position relative to the FG position, scroll settings, level height, and BG height.

in vertical levels most objects will no longer break up on horizontal subscreen boundaries (but they still will on vertical ones).

a limitation of the original game where sprites could not start with an FF byte has been removed (previously LM would silently move the sprite on save when it encountered this to avoid premature termination of the sprite list for the level).

levels can now have up to 128 sprites instead of 84 for non-SA1 ROMs.added a setting to the 'Change Properties in Sprite Header' dialog to control the sprite vertical spawning range for horizontal levels and an option for smart spawning.

the sprite loader now has a cache added by Vitor to reduce the performance impact from parsing most of the sprite list to access sprites on later screens.You can find the new setting controlling this in the 'Change Properties in Header' dialog, along with a new option that lets you view the full bottom row of tiles in horizontal levels. integrated an ASM hack submitted by Vitor into LM that allows changing the height of horizontal levels, effectively making it possible to change the level dimensions.Change log Version 3.00 December 25, 2018
