* My point is to use PSP Remaster Launcher because it allow to use minis2 config directly with decrypted ISO. With this patch I should be able to run test games very easy/fast, because I can use plain ISO + plain minis2.txt without need for external tools. I can then even edit config thru ftp text editor without need to do any additional steps (specially useful with black screen games). Is not necessary, just make things much easier. I'm interested in overall tests with games I have, not any specific game. --[[User:Kozarovv|Kozarovv]] | * My point is to use PSP Remaster Launcher because it allow to use minis2 config directly with decrypted ISO.

The key for minis2 is known, you can just use npdtool to encrypt it. ofc you can patch it to read unencrypted ones but whats the advantage?
are you interested in any specific game?
i patched some games and found some more configurations:

- My point is to use PSP Remaster Launcher because it allow to use minis2 config directly with decrypted ISO. With this patch I should be able to run test games very easy/fast, because I can use plain ISO + plain minis2.txt without need for external tools. I can then even edit config thru ftp text editor without need to do any additional steps (specially useful with black screen games). Is not necessary, just make things much easier. I'm interested in overall tests with games I have, not any specific game. --Kozarovv
