I'm trying to get the best compatibility for PS2 games and PS1 games as I can possibly get. I saw that Toxic OS has some great compatibility but was wondering about HD Loader. For Toxic OS and HD Loader if those are the best options, do I need to get the HDD addon for the fat PS2? The only way I see to get PS1 games to work is POPStarter which doesn't have the best compatibility. Is there any other way? Is Toxic OS able to run PS1 games? I have a fat NA PS2 if that matters. Any help on this would be greatly appreciated.
