A question about PSP Homebrew Firmware

Can firmware 3.40 homebrew upwards play PSX games on it? if yes, do i need any homebrew application software for it? thanks in advance guys..

If you have custom firmware you can run PSX without homebrew but the ISO has to be converted into an EBOOT - look here: https://www.romulation.org/forum/index.php/topic,572.0.htmlIf you have official firmware, you first have to install custom firmware. If you search Google there are many guides which will explain what you have to do in detail.
