I don't want to rain on your parade(s), but you can forget about playing any games except snakes and SRE. That's because the N93 does not allow simultanious buttonpresses. That is, it does if you first press a number button then a joystick button, not the other way around. Nor does it allow pressing two joystickbuttons at the same time (e.g. move and fire), or two numberbuttons at the same time =(
I'm totally frustrated by this. There ARE nice games, most notably SkyForce, and the NES, SNES and GB emulators by Vampent. There's also a (slow) GBA emulator, there's a Sega-emu and a MAME one. Also ColecoVision. And there's C2Doom. All of them look great (also on TV!!), but none of them are playable, because of this bug.
One: Who's Next looks absolutely spectecular. It CAN be rendered by the N93, but it CAN'T be played!!
I can only hope this is a firmware bug. They way this bug works leeds me to believe it is. I have tried contacting Nokia in numerous ways about this, but I haven't had a satisfactory answer. I ask everyone who cares about this to PLEASE try and contact Nokia too, so they might get the message and fix this with the new firmware release. It would also help if Symbian-related websites would pick up on this problem.
