Hi, I have 2 ps one games, Tobal no.1 and Covert Ops: nuclear dawn. I'm trying to create a memory card exploit using either one of those games. I've got the independence compiler 3.0, and so far I've manage to get Tobal no.1 independence exploit installer disc to work(somewhat). When I said somewhat, it saved the exploit onto the memory card but, when I reset the ps2 and stuck the original Tobal game in it it just booted up and went right to the Tobal game. To get it to work, I had everything check like the image up there ^ except for one thing, for the dummy file i had it at 0 Mb. I tried makeing it 100 Mb and it never worked. I never could get the Covert Ops game to work trying it with 0 Mb and 100 Mb dummy file. I think i wasted about 12 CD's on this >_<.
Can someone please tell me if I'm doing anything wrong? Any comments and suggestions would be greatly appreciated. if you would like to help me please feel free to PM/IM me my email is azn_boy108@hotmail.com. Thanks in advanced.
p.s. It is a modded ps2
