|  Re: Berks Four ... coming soon?
Thanks for all of the helpful feedback - I'll download YAPE and Plus4Emu to see which one works best with my system. The original Berks programs took full control of the machine so I should be able to use that code without too many changes.
I did try to limit the amount of player/missile graphics (Atari sprites) that I used so I'm hoping most of the code will transfer easily. The new location map system may be my biggest problem as that used bitmap graphics ... but I'm sure there will be a way around it.
The original Berks programs were released by CRL who went out of business many years ago - I assume the copyright reverted to me as they were my original titles? I do have all of the original code assembling via my Windows IDE but I hadn't really thought about a physical re-release.
I think it will take a few months to do the Plus/4 conversion of Berks 4 as the final game code was so large. I'll certainly ask if I hit any problems.
Thanks again,
Jon

I'm very near to completing the conversion of Berks Four and have a few questions:
The code assembles to a single .PRG file which loads fast in emulators but is it normal to add some sort of fast loader? The file is currently $CC80 / 52352 bytes - I haven't yet tested on physical media but I'm assuming that it will be rather slow to load!
The original release of Berks 3 allowed keyboard control of the main player as well as the usual joystick control. I've removed this at the moment as I've had to add a more elaborate keyboard routine to handle the password system. Does anybody still use keyboard entry rather than joystick for an action game?
Is it ok to upload here when the game has been completed?
