well any system CAN technically load any other systems data with the correct implementation and coding but If you code epsxe to load, boot, and run ps1 games it becomes a ps2 emulator. Anyhow someone should write a FAQ outlining common questions and why they will not work for various emulators. Like
q: why wont ps1 emulators run ps2 games
a: because they are two different systems. it's like trying to run a mac program in windows
q: can we put a ps2 bios into a ps1 emulator and make it work
a: no because they contain very different instructions.
