Yeah that can be a problem indeed, plus we have to not take online tools for granted, since after a while their author might abandon their site and shut it down (like what happened to the Map and Sprite editors by Aichi, because the author decided a Minecraft server would be far more important and useful than these two amazing tools). But of course you can keep it archived and use something like Doors CS to run it directly from archive (or Zstart does that too I think). That way you don't need to manually unarchive/archive your stuff over and over and you save on GarbageCollecting time. Any screenshots of your editor by the way?

If you want ideas or coding help, you can check this out It can be optimised a bit, but it uses a keyhook so all you do is press a special key combo and voila, the picture hex is in Ans http://www.ticalc.org/archives/files/fileinfo/427/42778.htmlActually, I think the source to that is wrong, but it might still help >.> The whole program is 72 bytes EDIT: That is over two years old o.o That could really use an update

Hmm, do you have the names of these programs, or does the user have to pass an argument telling what program to read/write from?EDIT: Here is some example code for getting the location of a var you have the name of:Code: [Select] ld hl,Name rst rMOV9TOOP1 ;Copies 9 bytes at HL to OP1.
