Emulator doesn't recognize multiple buttons pressed at once

[gmnr. appel]

I'm playing Tales of Eternia (the Japanese version of Tales of Destiny II), and my problem is that the emulator doesn't seem to recognize it when I press the square, cross and circle buttons together.

This combination is required to use Reid's aurora moves, which makes the final two battles annoying.

I'm using the keyboard, and I tried using a couple of different pad plugins as well as the internal one. I also tried switching from analog to digital mode, but nothing works.

Oddly enough, the directional keys work properly, because I can move the characters diagonally by pressing two arrow buttons.

Anyone else have similar problems?

You can't press more than 3 keys at once on keyboards, give up or use a gamepad
