If you're messaging about this game, yes, it's ridiculously difficult.
If you can't play at all, you might need to enable ActiveX in your web browser settings, or better still, just go to
www.romantion.net and download the
MAME emulator for your OS, and some
MAME roms. I discovered this site recently while looking for Joust 2.
All downloads are free and small filesizes, but I think there may be a daily limit.
