I managed it with big help from "Dirk V." to compile the classic ARM firmware out of gcc ported YQ100818 sources.
Jakub helped in getting scrolling work properly.
- page wide scroll of any file selection lists at Joystick/Cursor left & right including repeat scroll.
- OSD "fdd error" message removed since it mostly disturbed playing or inserting 2nd disk image.
- "FPGA Core" function menu to load any .BIN core file out of sd-card root directory including requester.
- some OSD text changes to be a bit more verbose or informative.
If there is any problem, please let me know.
C still is very new to me
The attached archive holds the .UPG file for sd-card update, the .BIN file for USB update and the source codes.
