XCEL game with kempston mouse support

I have XCEL game with kempston mouse support (my modification) in TAP format. Can anyone patch also TRD version with support SAVE/LOAD game position to disc ?

Only this TRD version support save/load to disc : http://trd.speccy.cz/gamez/x/XCEL_MER.zip

And here is my TAP version with mouse support: http://velesoft.speccy.cz/kmouse/kmvelesoft/xcel-km.zip (password is "k-mouse").

In Z80 snapshot is full source code of mouse driver and manual for patch game. If anyone send me unpacked BIN files from TRD image, I can patch it and send again.
