Paul Win10 shuttle PC 88a2d30858 Massive commit with bunch of random junk..
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.

Paul blue asus 535b45be27 Committing working build that was used for flashing STM8 SNES v3.1
boards for SF2 builds.  Not necessarily the most clean, but it was
stable and worked well.

Need to get swim comms working on other board designs.
Need to come up with better swim activation with more exact timing.
Still need to implement swim comms on avr, hopefully that doesn't prove
to be too much of a PITA...  Not looking forward to that.  Can probably
only handle low speed, and faking pullup may not work as well without
time on it's side @ 16Mhz...

Paul Molloy 0dd8828744 Long over due commit...
-Updated STM devices to always run @ 48MHz
 Doesn't seem to cause any problems with SNES flashing couple thousand SF2
 boards have been flashed with this build without issues
-Added note to usb_operations.c as manf/prod ID can't be read if drivers
 aren't installed.  Caused issues for Todd as he hadn't installed drivers
 for new hardware.
-STM swim operations are working pretty well for SNES v2 and v3 boards
 Haven't even touched SWIM on AVR core yet...
 SWIM is pretty pin independent but only implemented on EXP0 so far
 Reads "ROTF" aren't bullet proof but they're pretty good.  Biggest
 room for improvement aside from adding a legit pullup would be to have
 an interrupt trigger the device header bit falling edge instead of the
 current polling method which has decent amount of jitter.
 Implementing interrupts would also probably allow for more easily
 supporing reads longer than a single byte...

Paul Molloy 49b4639aa4 Have basic Low Speed SWIM read on the fly working.
Only reads one byte, but good enough.. to get things done.

Code should actually work for low and high speed, but have only tested
high speed on writes so far.

Having issue where reads can fail at times.  Esp with long strings of
'0'..  Perhaps operating at high speed would improve matters..
Although I'm also realizing maybe I'm not waiting for the device to reset
and reload HSI trim factory value, need to check that..

The new assembly file/function does everything needed so can start cutting
out inline assembly from swim_out function.

Swim code needs to run at 48Mhz.  Realizing this is pretty vital to having
enough time to handle high speed.  And timing of artificial pull-up
requires high trimmability..
