DM-41L memory editor tool?

[Dave Britten]

Got my DM-41L, and the ability to make and restore backups via putty is really handy. Are there any nice tools for manipulating these memory dumps, e.g. dragging individual programs/X-mem files in and out, editing registers and flags, etc.? Would be really cool to be able to dump the memory, move programs in and out on an individual basis, and transfer back to the calculator, in lieu of having something like a mag card reader or more X-mem modules for (relatively) mass storage.
