I've done some further testing with SicGen and SDXImageUser on my XP PC.
SicGen:
I can only drag-n-drop one file at a time, sometimes a file will not show up in the grid list, while other times it will.
Q: Are Atari Binary Executables the ONLY type allowed? I'd like to add some basic or atascii files too...
Bugs:
If you add a file and haven't saved the rom file, then exit accidentally, the program doesn't ask if you want to save it first.
Found that the program can crash if you try to move the rows in the grid list.
Sometimes when Loading a Cartridge rom from the File Menu, the contents won't show until you choose the File -> New Menu.
SDXImageUser:
How can you create a Blank 256k or 512k image? The rom image created by SicGen only shows 8192 bytes left when it's empty.
If I load the 256k SDX 4.44 rom image and delete all the files, it still shows 8192 bytes left?
Otherwise, How can I create a 512k SDX 4.44 rom with other files on it too???
