Changing 41C XROM numbers

[derekamos]

Yes - on a PC you would need a copy of Meindert Kuipers MLDL2K.exe. This is like a PC debug program, but aimed specifically at the HP41 series, and ROM/MOD adjustments.

As long as you have a .ROM or .MOD file that can be loaded on the PC, then there is a host of control header features you could alter, including a roms name & number.

Doing this with a debug PC style program will not allow checksum recalculation, but this program will. It really is the way to go - as the program is excellent.
