Hi,
in fact when I made a technical demo in BASIC (comparing snail speed soft sprite emulation in BASIC with GSHAPE, DRAW and POKE methods) I definitely switched to Graphic3 mode, and after some successful tests I saved the program to HDD as PRG.
Next day I reload the saved program, and there was nothing to list.
So I also noticed this (definitely known rule) that after mode change the BASIC reallocates to $4001. But first it was a very confusing and irritating moment, I though I lost 3-4 hours of work.
But in fact, just loading the program as a PRG from menu, will load the PRG to it1s save address, and it is $4001, but if not set to GFX mode in advance, the BASIC will look for the loaded PRG at $1001, and will list nothing after load.
Loading from Disc or Tape is a different matter, as you can use the LOAD"",8 or DLOAD"" method.
So I learned those thsick, for me the solution was to transfer it to a D64 with Disc tool, then load it with DLOAD from D64.
I do not know, is it not possible to identify, if the PRG is a BASIC one, and based on the expetcetd know BASIC start address, load to THAT address the PRG?
