i did this to a bunch of programs, from image editors to tomtom, and even the camera on our phone loads quicker because of it. it basically decompresses exe's and recompresses them.
it really made a difference. i dunno if its been talked about here, i've never seen it so i figured i'd let some people know. you just copy the exe's to a folder, run a program, and drop them back in. it won't make the programs run faster, but it decreases their load time significantly.
there's a list on xda that is being updated apparently, but i'll start one here too. I ran a backup with sprite, and the backup came out fine. i haven't restored it yet, but i'm recompressing the original exe's with the 1.1 version. the 1.1 version disables icon compression, which should fix the sprite problem if it exists.. i'll let you know what happens when i restore.
(on a side note, i took the compressed exe of tomtom from the 1.0 version out of a sprite backup, and it runs fine.)
as of now, i've compressed and had good results with:
cfinstasller (pocket express, the other exe's aren't able to be compressed)
camera
explorer.exe (resco file explorer)
googlemaps
htcalbum
irisbrowser
kinoma
musicid
opera9
pbox_dl (pencil box)
photogenics
pocketartist
pocketgravity
powersms
rcapture (from resco photo viewer pro)
rpicviewpro (resco photo viewer pro)

s2u2
s2v

here's a list of exe's that should not, or can't be compressed for various reasons. .net files aren't supported.
manila.exe
cprog.exe
thumbCal.exe
calculator.exe
wt5jetpr.exe
AdvancedConfig
GNAgent.exe
TaskFacade
task manager v3.1
coreplayer
htorch
pocket twit
billiard master 3
omniapiano
comic reader

livesearch

if anyone has a problem with any exe, pm me and i'll put it here.
i'll be working on more after i recompress them with the new version. i recommend keeping a copy if your original exe's on your computer just to be safe, in case something goes wrong you'll at least be able to fix it without a hassle. don't try dll's, it won't make any difference in speed, and can/will cause problems.
also, another thing i noticed with the 1.0 bat file, is that since the icons were compressed, thumbnail icons didn't seem to be working in programs like resco explorer. 1.1 fixed that.
1.1 is an updated version just posted on xda to fix the problems with sprite
