Yes it has everything you need.

What FW are you on? If its 2.xx+, you need to lose the System.usbDiskModeActivate()
line. It makes my scripts not work.

I looked at the tutorial and tried it myself, and using some debugging, I found that it crashes when it gets to
splash = Image.load("images/lua.gif")

So I made a jpg of the file and corrected the code.

In future, if you cant tell where your program crashes, try writing the following after each line of code in the area you think is a problem

screen:clear()
screen

rint(194, 136, "CHECK [x]", white)
screen.flip()

NB Must define WHITE if this is used

use a different vlaue for [x] each time you use this idea, and then you should get to a certain CHECK. Say you never reach CHECK 6. The line of code that comes before

screen:clear()
screen

rint(194, 136, "CHECK 6", white)
screen.flip()

Is your problem line!

ran your script, and got a 'no script' error, is that what you got??

Im on 1.5 firmware. And yes I did get a no script error, thanks for your help so far.

chrispy · #7 (**permalink**) 03-30-2006, 11:41 AM

OK then.
I was gonna attach the script, fixed, but my psp is upstairs charging, So I cant (be bothered)

What I did was loaded it into ttlde 1.7, a Lua App for PSP which is a lua IDE. Its real easy to use, and you can compile it from within the program. If theres an error, it helps you out, rather than just saying 'error'

I suggest you find a copy of ttlde, and debug in that. I dont advise TTLDE for writing lua, just debugging for PSP.

ok thanks verymuch, could you please upload the debugged file when your ready? Thanks
