XXEdit (aXe heX Editor) is the evolution of my old Axe Memory Mapper. It is a comprehensive memory mapper and editor for the z80 series, designed to be a superfunctional form of Calcsys. It is highly useful for helping debug Axe and assembly programs on calc.
Features:
Memory bank switching
Display of addresses in hex, decimal, and in the form of pointer+offest
Quick access to L1 (saveSScreen), L2 (StatVars), L3 (appBackUpScreen), L4 (tempSwapArea), L5 (textShadow), L6 (plotSScreen), $4000 (the start of Flash), and $8000 (the start of RAM and appData)
Display of byte in hex, binary, decimal, ascii, the two byte number at that point, and the 8x8 sprite of the 8 bytes at the cursor position
Jumping to the currently highlighted two byte address
Jumping to any user defined hex address
Search for any 8 byte string. Accepts input in both hex and ascii
Search for any program/protected program/appvar in RAM or archive.
Edit up to 8 bytes at a time of current cursor position, input accepted as hex or ASCII
Edit via sprite editing of the 8 bytes at the current cursor position
And probably something else I forgot...

Thanks.

Unfortunately, I've found a rather serious bug lol. It leads to a mess of garbled text followed by a spectacular ran clear. It's actually kind of cool. It's triggered by trying to change the value of a single byte to $00. So uh, yeah, don't try that. I'm going to have to rewrite how this thing handles hex input... Mergh

Basically because, since you are allowed to enter a variable amount of hex, I use 00 as the 'null byte' to determine the end of where the engine should stop copying hex. So I'm guessing entering $00 tells the engine to copy something with 0 length, which it does not like at all. Anyway, here's the patched version

As perhaps a feature request, maybe there should be an option where you can, if searching for a program or something, there is an option to display the z80 dissassembly of the program.

I need to try this eventually.

That would be cool. Just make sure it won't be as buggy as Omnicalc's clipboard function, tho, lol
