As soon as QNICE V1.7 is released and issue 198 of QNICE (sy2002/QNICE-FPGA#198) is resolved, we should refactor the un-(q)nice embedding of the Monitor that works with code duplications and finally remove these files when done:

MEGA65/QNICE/qmon_gbc.asm
MEGA65/QNICE/monitor_vars.asm

Write some config file to the /gbc folder to store configuration settings such as custom key and/or joystick mappings

Needs a newer QNICE version that can actually write to FAT32 (currently, there is only read-only support)

Make the keys configurable

strcpy

QNICE V1.7 comes with a strcpy operating system function, so replace redundant strcpy routines by SYSCALL:

• dirbrowse.asm has _DIRBR_STRCPY
• llist_test.asm has _DIRBR_STRCPY

ENTER/LEAVE

QNICE V1.7 comes with ENTER/LEAVE functions so tools.asm can be thinned and the respective calls can be replaced by SYSCALLs

As soon as QNICE V1.7 is released, we can get rid of qnice_mmio.vhd because V1.7's MMIO controller already lets us switch off PORE using generics.

So we will be able to delete the local copy of qnice_mmio.vhd and just change the usage (switch off PORE) in MEGA65/vhdl/qnice.vhd: mmio_std : entity work.mmio_mux

Support RAM persistence (savegames)

Needs a newer QNICE version that can actually write to FAT32 (currently, there is only read-only support)
