 |  Re: Introducing CBM-Command for the Plus 4
My previous post wasn't about the config program but about the LOADER 
I dled the new version earlier today and noticed the black screen.
Btw, is there a list of system specific zeropage addresses you are using? I'm not talking about zeropage addresses that are just "used" as counters etc but those which are used by the kernel (e.g. 186 on C64 = 174 on plus/4). I could check those to see if they are all ok.
Something else:
The routine restoring the F-keys at $10b4 can be replaced with
STA $FF3E
JSR $F397
STA $FF3F
(that'll take care of a few other things as well).
If you want a more flexible solution, you should read the F-keys' content on program start and restore them when quitting. Especially for users with EPROM BANKS/cartridges this is better because many of those redefine the F-keys and place a STARTING COMMAND on one of these. For instance, the built-in 3-plus-1 software on plus/4 changes key F1.
