After apply this patch to your ROM, you can use a scroll PLM in the same way as before.
In ordinary circumstances, the "High" and "Low" bytes are actually a pointer to data in bank $8F.
If the number of "High" is less than $30 in smile, you can specify the number directly.

Scroll PLM "High": which screen do you want to change. (00--2C)
Scroll PLM "Low": what number do you want to change to. (00,01,02)

Ex.(001.jpg): The second screen turns into green when samus touches the PLM.

Default: $848B63--$848B65 change 3bytes , $84EFE0--$84F003 use 35bytes

Please tell me if there are any problems with this patch.
