Patcher by James Montelongo.

If you simply want to patch mirageos, copy it to this folder and run PATCHIT.BAT. The MirageOS app should be named MIRAGEOS.8xk. It will output MOS_PATCH.8xk.

If you want to use patcher for other things:

syntax for patcher

Patcher APP.8xk patch.hex

app.8xk must be a typical 83+ app, 1 page only (size on calc 16384).
Patch.hex is standard intel hex.


The patch format:
:XXYYYYRR...data..CC

XX is the number of byte in data.  Should be able to suport any 8bit length.

YYYY is the address line that is to be over writen, for example 4012 is where the name is generally stored.  The address must be with 4000 and 7FFF or it will crash.

RR is the record type, only 00 and 01 are support, NOT 02 or others. 00 means data record and will over write data in the given app. 01 means END record it will stop patching if an end record is hit.

...data... is just hex data.

CC is the checksum. IT IS IGNORED, but still put the byte there, 00 will do.

So an example of a patch file is this

:084012004D4F53204841434B00
:00000001FF

That would change the name of an app to "MOS HACK"


Patcher only outputs a patched BIN file( called temp.bin), You must sign with Wabbitsign if you want to use on calc.


I do not accept responsiblity for anything that may go wrong. If you use, use at your own risk.  Also don't go around releasing modded apps, its WRONG!!!!!!!
