I made a commit earlier this week but messed things up by not pulling
from the master and things weren't updated... Here's the notes from
that commit:

Large commit biggest feature add is NES MMC3 support including Save RAM
(aka WRAM/PRGRAM) support including dumping and writing save files.
The MMC3 script & method of dumping/flashing is the most forward
thinking script/firmware so far. Finally starting to form a clear
vision of how I want to handle flashing/dumping variations with mappers.
Biggest thing is having the host handle the mapper init & banking
control. In the view of the firmware, it's only responsible for knowing
how to flash a bank. And dumping is even more generic with the host
just telling what address range to read. Things will get more complex
with support of mappers with bus conflicts. But ready to start
converting these old hacked methods to be more like the MMC3 means.
Have some early support for dumping gameboy using the snes script as the
pinouts are nearly identical. Along with testing of toggling between 3v
GBA and 5v DMG.
Have some early support for INLretro NES only version which uses a
smaller mcu because it doesn't need to support large 16bit carts. Still
have to get this completed.
Added support for CNROM, but I'm not sure if it's actually working. Going
to restart with NROM and start updating the currently supported
mappers to be more like MMC3.
But this also includes some new updates from the second half of the week:
Started updating existing NES scripts to use new MMC3 methodology. Got
NROM, CNROM, BNROM, & Color Dreams working. On the host side only
needed to add nes.c functions for specific flash algos. Able to delete
significant amounts of mapper specific code from flash.c
Got some basic SNES script support with new methodology for Catskull
elect 5v PLCC SNES LoROM board. And INL SNES HI/LO-ROM 3v board as
well. These don't yet use buffer writes, just single byte writes.
Also having issues with Mirroring test/sensing again. Driving me crazy,
but don't really care about it at the moment and not sure what's wrong..
So just committing that broken for now. Looking to remove this
functionality from the firmware side as the host should be controlling
most of this.
Looking to add SNES RAM & buffered writes. Also need to test some of
the HIROM code as I just added it in there while I did the LOROM stuff..
Added windows driver package, just have to run InstallDriver.exe to
get drivers installed on windows 10 (and others I believe)
Created dictionaries for all remaining cart connectors.
Nothing useful there yet, just wanted to get the files created
and dictionaries working.
Added bunch of notes to shared_dictionaries to explain how to go
about creating new dictionaries and some opcode details.
Have STM8 cic communications working "CICCOM" to change between H/V
mirroring on new discrete boards. Currently these operations are handled
entirely from the host scripts and opcode/operands are mostly hard coded.
Need to move these to more generic functions in the ciccom dictionary
which will also speed things up moving to the firmware which will speed
things up.
Some changes to mapper 30 script to eat the ines header, and test CHR-RAM
banking.
Some updates to snes flashing operations, still a work in progress to
fully support prior SNES board designs.
