Porting the psone to psp. . .

I have quite the idea everyone but. . . . first i need YOUR HELP. I need to first convert the psone games that i own (like 2 for starters) into .iso format. Does anyone know any programs to do this? Please research, search your torrents, most trusted sites, ftp's, etc! No i am NOT looking to pirate or anything i own all my psone games! Come on Final Fantasy, Tony Hawk, and Metal Gear fans help!

Whats my idea? It's secret no im kidding but i'd like to try the idea out first, won't take long.

I seriously think the whole difficulty of emulating the psone is seriously being overlooked.

Try Alcohol 120%. There's a free trial version around the internet that'll help you with what tou need.

im guessing you want to change the psone games to use psp instructions...

Dont we call that ron cana. LOL

It sounds more like he is trying to run the ISOs via the standard ISOs loaders for the PSP. (clue: "It won't take long"). Rewritting the instructions will take MUCH llonger.

Won't work, the PSP architecture is different to the PS1. Even the CPUs are different enough for the two to be incompatible at least without a recompile.

yeah i'll admit it the idea was to format it into .iso and then run it via devhook or fastloader and neither worked gotta admit its not that crazy there both the same format of file. . . .

and thanks i did use alchohol120% i have a feeling i'll need that in the future for the ps1 games i have.

The same 'format' of file is irrevelant. The instructions in the binary executable would be different as the platform hardware is different (at least).

But there are a lot of similaritys between the two

Similarities != Same
For example, the PS1 uses a custom MIPS R3000 as the CPU, the PSP uses a custom MIPS R4000.

There could have been any number of changes in the instruction set (even more so when they have been modified). It's like trying to navigate around the world now using a map from the 1800's. You can expect the layout of the world to be 'similar' but hell, you are going to run into trouble when one area is not the same anymore.

A better example is the current N64 emulators. The hardware is 'similar' to the PSP's (at least in regards to the CPU) but yet the developers had to write a dynamic instruction translater from the ground up to even get the games running.
