I have been having the same issue getting it to run full screen/full size in Windows 7. I've finally got it working with the Lost Isle build of ZC and 1.92 b183.
I tried using the 640x480 compatibility mode with XP, 256 bit color mode, with every parameter on the Zelda Classic executable. Here's the fix that finally worked for me.
First download Zelda Classic Launcher from
http://www.deviance....assic-launcher/Place it in the folder with ZC (whatever version you want to use). I turned on Administrator Right by -right clicking, properties, compatiability, priviledge level, though I don't know if this is necessary. Once that is launched, select 640x480 resolution full screen and enjoy. I didn't have any other option selected under the Zelda Classic launcher.
The only issue I ran into with this setup was the color pallette was out of whack using 1.92 b 183. I used the batch file fix here:
http://www.purezc.co...o...&pid=623456 or at the top of this post to fix the color pallette issue.
Hope this helps you guys out. If you run into issues where explorer won't relaunch if you have to use the color pallette fix, after you quit ZC, press alt-control-delete, and launch task manager, then select file, run, and type in explorer.exe and that should launch the desktop fine.
