Hi Blaze, welcome back.
Re: Dynablaster, there doesn't appear to be any way to activate the remote bomb without a keyboard at the moment. I'll leave a request on the Mantis page for the WHDLoad slave.
Re: Cannon Fodder, unfortunately not. My recommendation would be either to look into getting an Amiga mouse or the PSX to DB9 adapter (
http://www.kipper2k.com/PSX-Adapter.pdf), which will let you use the thumbstick on a regular PS2 controller as a mouse.
Re: Alien Breed. Use a pad in the other port to get past the levels disk screen. Not sure what the issue with the other games is though :S it could be a random glitch, have you left the console off for a few minutes before trying again?
