The Z thank you
VERY MUCH for such a fast and wise reply

But what do we expect from close neighbors is it not? (I am from the east in The Netherlands)
I asked a lot of question since it's been ages for me I even touched my PSP. It's still shiny and like new from the shop. It's the Phat 1004 (I know the 4 means from Europe) and bought it back then when it first came out. Only played 1 or 2 games on it and I moved it aside. But now I am liking it very much again. I like to play and rip first my Final Fantasy 1 and 2 Anniversary editions from UMD to an ISO and put it on my memory stick. A) For reservering the UMD drive longer and B) It's more easy and a tad faster loading times.
Just a question. If I were to keep my old 5.00 m33-4 release from Dark Alex then I probably won't be able to load up many UMD games. Does this have to do with the firmware installed on my PSP right now? Like when a new game on UMD disc needs a newer firmware than my custom 5.00 m33-4. it asks to update? Or is it something else that causes this?
Before I will start the procedure of updating I read
HERE and
HERE trying to upgrade from an older 3.52 m33 to 6.60 and came upon those 2 errors. The "DADADADA" one and later on the "DRNFFFFFFCD" as well. That seemed to suck hard if you read the whole topic. Is there any change I will face the same problem?
Or can simply upgrade from 5.00 m33-4 to OFW 6.60 right away and then install the 6.60 ME-2.3 CFW? That one should probably be somewhere here to find, right?
Hope the ripping from UMD to ISO will work as well. Btw, I remember playing FFVIII back in 2009 or so when I used it last (not thE PSN version but the PSX one and probably made an EBOOT of it back then using POPStation? I can't even remember...) on my PSP and have the 8gb memory stick with the iso on it. Will I lose the savegames from it when I go to the 6.60 ME-2.3 CFW? Or is it saved on the memory stick somewhere together with the game? I should check this out soon.
Thanks again and hope you can answer a few more of above question hehe.
EDIT: I already found all the files necessary to update
Only question remains if it will not screw my PSP from the 5.00 m33-4....
Also I did find the alternative PSP Filer program. In the "install.txt" it cited:
"how to install Filer
firmware 1.0:
copy GAME150/FILER150 folder into ms0:/psp/GAME/
firmware 1.5:
split GAME150/FILER150 folder using freeware (e.g. ExportPBP) and copy those two folders
splitted by the tool into ms0:/psp/GAME/
custom firmware:
copy GAME150 folder into ms0:/psp/
and create ms0:/psp/game/ folder
kernel-3 of custom firmware (e.g. PSP-2000):
copy GAME folder into ms0:/psp/
some features do not work, see GAME/FILER/warning.txt."
So if I am correct I need to create an empty map called "game" directly under the psp map? Followed by copying the whole "GAME150" folder and it's EBOOT.pbp (program?) in it under psp folder as well?
