CD// does return to the root but not from within a .d64, you need a to use CD{left arrow} first then CD// to return to the root, if you're within a sub-folder that is. To absolutely return to the root folder from anywhere (even within a .d64) just issue a U{Shift-J}, this is a hardware reset that re...

I parsed part of that as: [...] No, that's not how the SE appears in the CPU address range. Rather: - 3 KB additional RAM in the range $0400 .. $0FFF (corresponding to the /RAM1, /RAM2 and /RAM3 signals on the expansion port), - 4 KB additional ROM in the range $A000 .. $AFFF (lower half of BLK5, p...

Got mine not too long ago and it's #245, so I would guess getting close to 300 maybe.

Right, powering down will reset all RAM, if it didn't then the first time you caused your computer to freeze-up it would do it every time you turn it back on.

Instead of powering down have you tried a reset button? That would reset the system but RAM will retain it's contents.

Once you've placed the values into the keyboard buffer do a JSR to $EBD6 that will reset the Port B I/O register, effectively wiping out the CHR$ code for the key.

I can't physically create a cart for you but here is a cart image that you can try out. If you have a 8k or 16k RAM cart that can be configured to block 5 ($A000), load this with the usual: LOAD"JEFF-CART",10,1 then insert a disk in drive 10 and reset with: SYS64802 Or you could try it out...

Like I said, (Crappy cell phone pic). I'll try to get my 14MP camera and take another with better lighting. I think my cell only does 4 or 5 MP. Edit: Here is a better pic, using a better camera. I think the colors were washed out from the lighting in the first pic. Hope this one helps. The type of ...

How about flipping up/down instead of left/right?
Then only the top and bottom need to be the same size.

Nice work, btw.

I compared V1 to V2, only difference is a few CHR$(13)s removed in V2 at lines 660 to 675. Looks to be pure BASIC code, no peeks or pokes, and looks as if it was typed in from a listing in a book. The menu format does seem to be suited for 40 columns. When loaded into a C64 the menu looks ok, and ru...
