DDT Question

[TGB1718]

Using Altirra, I attached the MAC/65-DDT Cartridge (normally I use the disk based versions of MAC/65 and BUG/65)

The main reason to try this is to use DDT as it's built in and BUG/65 had a few quirks when using SDX (U1M).

 

It seemed to work except no cursor keys ? so I can't scroll through the display which makes it useless, I tried booting

from a DOS floppy (no SDX), but I get the same result really strange.

 

MAC/65 seems to work fine.

Check your emulator settings - usually you'll probably have the cursor keys set to act like cursor keys (as if pressing CTRL on the Atari).

 

But Mac-65's DDT does scrolling through the disassembly by just using the keys without CTRL.  Handy on a real Atari but in emulation you'd have to hold CTRL as well - or just set the keyboard option to use the cursor keys as if CTRL isn't held.

Thanks, checked all the keyboard settings, changed just about everything, but still no joy,

however, looking at the mappings, I had a clue that the cursor movement used '+' and '-' keys.

 

So in everything else I can use the cursor keys (without Crtl) but in DDT I have to use '+' and '-'

again without Ctrl key, so problem solved, but don't know why it's like that.

It's like that because DDT controls the cursor with the -,=,+,* keys, just without the CONTROL key. Normally, these keys move the cursor in the Os editor with CONTROL pressed down, but in DDT, CONTROL is not required.

 

More convenient on a real machine, less convenient on an emulator.

No, I tried all combinations, nothing works as @thorfdbg says, it's the way DDT handles the keys

Also I believe Altirra won't pass through any key that's assigned to a joystick or other controller function so check that as well.

Easiest to just disable any controller mappings.
