Huh? do you want to convert a LR screenpack to HR or viceversa? you're not being clear.
Anyway in short to convert a LR screenpack to HR you would need to reduce all the select screen related sprites by half the size and also reduce the values on the system.def by half as well.
That's the general idea.
In other words:
- extract all the sprites for the screenpack's .sff (use sffextract on winane's website, there was a windows application called SFF2 Turbo Revival that made it easier to use made by Dark Saviou but I'm not user if it's still online).
- then reduce the size by double of every select screen related sprites (for example if the sprites is 320*240 reduce it to 640*480)
- also chage the values on the system.def by double.
For example:
[Select Info]
rows = 30
columns = 24
wrapping = 0
pos = 5,1
showemptyboxes = 0
moveoveremptyboxes = 0
cell.size = 10,10
cell.spacing = 3
cell.bg.spr = 206,1
cell.random.spr = 151,0
cell.random.switchtime = 4
p1.cursor.startcell = 0,0
p1.cursor.active.anim = 205
p1.cursor.done.spr = 161,0
p1.cursor.move.snd = 100,0
p1.cursor.done.snd = 100,1
p1.random.move.snd = 100,0
p2.cursor.startcell = 0,23
p2.cursor.active.anim = 204
p2.cursor.done.spr = 171,0
p2.cursor.blink = 1
p2.cursor.move.snd = 100,0
p2.cursor.done.snd = 100,1
p2.random.move.snd = 100,0
random.move.snd.cancel = 0
stage.move.snd = 100,0
stage.done.snd = 100,1
cancel.snd = 100,2
portrait.offset = 0,0
portrait.scale = 0.4,0.4
title.offset = 159,13
title.font = -1
[Select Info]
rows = 30
columns = 24
wrapping = 0
pos = 10,2
showemptyboxes = 0
moveoveremptyboxes = 0
cell.size = 20,20
cell.spacing = 6
cell.bg.spr = 206,1
cell.random.spr = 151,0
cell.random.switchtime = 4
p1.cursor.startcell = 0,0
p1.cursor.active.anim = 205
p1.cursor.done.spr = 161,0
p1.cursor.move.snd = 100,0
p1.cursor.done.snd = 100,1
p1.random.move.snd = 100,0
p2.cursor.startcell = 0,23
p2.cursor.active.anim = 204
p2.cursor.done.spr = 171,0
p2.cursor.blink = 1
p2.cursor.move.snd = 100,0
p2.cursor.done.snd = 100,1
p2.random.move.snd = 100,0
random.move.snd.cancel = 0
stage.move.snd = 100,0
stage.done.snd = 100,1
cancel.snd = 100,2
portrait.offset = 0,0
portrait.scale = 0.8,0.8
title.offset = 159,13
title.font = -1
You can see that values like pos and cell size were doubled.
