Issues holding L1, L2, R1, R2 simultaneously

[secretUSER]

I was playing LOTR ROTK for the PCSX2 and a certain move requires pushing of the aforementioned buttons simultaneously. I attempted it multiple times (by pushing the fours buttons on my keyboard that I assigned for each) and could not get the desired effect. Has anyone else had this issue? Is it likely a problem with my configuration (e.g. I need to configure a simultaneous button to push all 4 at once) or with my ISO?

Playing with keyboard or pad ?

Are you sure your keyboard supports 4 keys pressed simultaneously? Older keyboards had a limit of only 3.

not just older keyboards, but lower-end (basic) ones.

for the OP: if you want to be able to do something like that, you will either need a controller (cheaper), or you will need a higher-end gaming keyboard. The feature you are looking for is n-key roll-over

Keyboard, found that it didn't work whether it was an external or the one my computer came with, and I'm pretty sure my computer is relatively new.

Ok, I'm getting a controller soon, but for anyone wondering, you can set the four bumpers twice: once individually, and another time all to one other key.
