Switching to 1.5/2.0

I have the downgrade already to copy over to my 2.0 PSP. Once the files are in place can I leave them on there or do I have to delete them?

I'll explain what I want to do.

The demo disk provided has the 2.0 update so if I copy then install the files to downgrade and leave them on, When I want to switch back to 2.0 can I install the update from the UMD and the files for the 1.5 will stay where they are or does it over write the 1.5 files so I have to copy them across again?

Mr O

 

Your installing 2.0 from the umd so that has nothing to do with the memory stick, when u wanna upgrade put the demo in, when you wanna downgrade put ur memory stick in with the mph downgrader....
when ever u wanna downgrade just put the downgrader on the memory stick, or do it like i do i use 2 memory sticks, 1gb and 32mb i dont use the 32 mb so i keep the downgrader on that ready to downgrade. After u downgraded u can delete the files off the memory stick which means u have to copy them over again next time.

 

for safety reasons, id keep the downgrade on a 32MB stick so you dont end up doing something mistakingly, or having someone else do it.

 

Thanks for the replies. I have a 32MB card and a 2GB so i can leave the 1.5 downgrader on the 32MB card.

Thanks again thats a big help

 

is it bad to downgrade and upgrade as you please? like, is there a limit in how many times youre allowed to do it or something? i dont do it cauz i got enough bricks in my house, dont need another

 

Ive downgraded and upgraded about 50 times when mph wasnt out....

 

is there a need to upgrade to v2.0?

 

Well there was back then because i wanted to play gta and use internet browser..etc so i had to upgrade, but now that mph is out its staying on 1.5!

 

Can you play new original UMD games (that require 2.0+) on a 1.5?

 

Yep using mph game loader, run it and bam! 2.0 game on 1.5!
Put the MPHGameLoader folder into the root of ur memory stick, and copy the two folders MPHGAMELOADER% and MPHGAMELOADER to psp>game.
Certain games dont work, heres the compatabilty list: http://forums.afterdawn.com/thread_view.cfm/308604

 

That list is for ISO's only, I'm talking about original UMD's that require 2.0+ working on the 1.5.
Does the MPH allow the UMD disc games work with 1.5?

 

Yes u can load umd 2.0 games on 1.5 with the mph game loader, http://www.maxconsole.net/forum/showthread.php?t=16536
But if its an old umd then u can use wab version changer or pspset to trick ur psp into thinking its a higher firmware e.g 2.0

 

you umm still didn't answer his question jaskaran, that link doesn't help him with his question

 

Ive told him what to do with mph game loader, instead of telling me i didnt answer his question maybe u could help him out?
