Hi Geir,

Alternatively you can save those three ROM images in RAM into Flash and plug the User ROM XXXF image already in the IMDB. You need to be extra careful when erasing/writing/copying into the Flash area. XXXF is already setup in the IMDB for 16K User ROM image.

First you need to copy YFNZ from Flash to RAM. Since you need to be running YFNZ from RAM in order to make changes to Flash. Then Plug YFNZ to 1L using the RAM location where you saved it "8XX-RAM" PLUG1L

Erase the Flash sector from 0E0-0E7 (which will erase any previously saved User ROM images in XXXD, XXXE and XXXF if there is any). You can only erase Flash one sector or 8 pages at a time. So if you have any ROM images in those areas that you want to retain, you may want to move them to RAM before erasing that Flash sector so that you can copy back to Flash afterwards.

Copy the ROM images you have in the RAM to Flash, 834>0E4, 835>0E5 and 836>0E6 using YFWR

Plug Flash version of the YFNS by "YFNS" PLUG1L to protect any further changes in Flash.

Now you can plug these ROM images by using XXXF.

I have limited the details of the recipe in order to prevent inexperienced users erasing or corrupting the Flash area unintentionally and potentially bricking their calculator. Let me know I can provide more details.

Another method, you can copy these images saved in RAM into an empty part of the Flash above >180 (first must Erase that sector), then use 41CL "Extra Functions" or YFNP, IMDBINS to insert a proper image ID with that Flash ROM image address location. Now you can plug these modules with your own image ID.
