 Re: Plus4Crt3: still buggy! Help!

It doesn't need to set the font address, as it uses the default font and the kernal for printing text.

Maybe you haven't set the Characters font address?

I found the bug! happy I was using the wrong addresses to swap the kernal in and out in the getkey() function while waiting for a key press. Now, I need to fix a reset bug. It should be easy to fix: I'm using jmp ($FFFA) where I need jmp ($FFFC).

 Plus4Crt3: still buggy! Help!

Hi! A while ago I started some cartridge libraries for the Plus4. I currently have three online at https://sourceforge.net/projects/cc65extra/files/memory%20cfgs/. Version 1 is a 16k cartridge setup, Version 2 is a 32k setup where the upper 16k is banked in only for read access, and Version 3 is supposed to be a full 32k setup where the kernal is only banked in on access. Version 3 is buggy. sad The symptom is a lock-up while either writing text to the screen or waiting for a key press. I want to try to fix it. If you have any insights as to what's wrong. please reply.
