on provided prg/chr rom input args for dumping. Mirroring is sensed &
entered for fixed mirror mappers. So this is basic iNES file format.
Still don't have automatic banktable locating, nor mapper detection.
But this provides a basic header that should work with most currently
supported NES mappers. If the headers need tweaked, I recommend opening
in Mesen and using it's header modifcation tool.
this is the verion getting flashed on all v2.0N NESmaker kits
v2.3.0 worked for basic functions, but was never shipped
Majority of effort revolved around testing mapper30 boards with the
smaller v2.0N INLretro with the NES connector alone for NESmaker kits.
added linear feedback shift register for test stream data generated
locally on the device. I'm not 100% sure if this is any faster than
pushing the actual data via USB though.. :/ It's plenty fast on the
stm32 nearly instantaneous for 32KByte. But the AVR takes a couple
sec..
Created "stuff" dictionary for things like that were I just want to add
small things and don't want to bother with a whole new dictionary.
Added file verification to the host with files.lua
Have some nes flash algos return post-written data so calling function
can decide if want to retry, fail, etc.
Changed host dictionary calls to assert instead of error because it
really shouldn't continue. I didn't see an error when sending opcode to
wrong dict and caused head banging..
fwupdate permits bytes to be skipped, or force the update. Found that
the fwupdater got assigned different addresses of ram depending on what
all other ram gets allocated to the main application
Some clean up of inlretro.lua
TODO:
host learn and keep track of the connected device.
Needed for ciccom right now, or knowing whether ciccom connection
is even present..
In the end maybe ciccom is better placed in firmware, but for small
transfers of only a few bytes it kinda makes sense to keep on the host.
Pinport gets quite messy with these made up pin names when really all I
want to do is toggle a specific pin on the NES connector. So maybe some
double mappings would actually be okay, need to rethink that..
create different flash modes that either keep going, retry, or error
depending on the goal of the flash operation. Fanout the return value
from flash algos to all of them.
have fwupdate assigned a specific area of ram so the ram pointer doesn't
change between builds. Okay to ignore for now.
Realized can have STM32F070C6 devices execute bootloader by erasing all
the flash or perhaps even just the first word of flash according at
AN2606. This wouldn't work for RB devices though. This could be done
through the bootloader dict
NES scripts to use new dump/flash methodology that MMC3 started.
Includes BNROM, UNROM, MMC1, and new scripts for FME7 & MMC4 (SOP flash).
Adding more general support to SNES with v2proto_hirom that script is
actually becoming more of a master script supporting both LoROM and
HiROM including flash, dump, and save backups.
SNES Rd/Wr now designate the state of /ROMSEL so have to manually
determine if access should be in /ROMSEL space of the SNES memory map or
not. (ie all SNES cart memories are /ROMSEL space except HiROM SRAM).
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.
Mostly adding support for mappers as I needed it for my own hardware
builds:
-MMC1
-mapper 30
-easy NSF (still need to update for mapper verilog fix)
-action53 (still need to update for mapper verilog fix)
-dual port board flashing
-colordreams, not sure if I actually got this working
-color ninja, just a special CPLD version of colordreams for ninja boards
Just started working on SNES code. slowly getting things up and working
outside of main inlretro.lua script similar to how NES has been handling
everything with it's own script. Able to flash v3 boards fine. v1 boards
flash without errors, but still having some mapping problems where it
verifies but won't boot. v2 prototype flashes most bytes but not all,
seems v2 boards are much slower to output valid data.. But that may just
be the manufacturer ID codes..?
TODO next:
-bootloader dictionary that jumps to bootloader so don't have to manually
close jumper on the board.
-turn on the watchdog timer for stm32
-create some sort of host timeout so reset button on programmer isn't as
useful
-allow firmware programing algos to be uploaded and executed from SRAM for
faster code that also doesn't require specific firmware builds to support
new mapers.
-Finish JTAG to simplify programing NES & SNES CPLDs
-Sort out swim issue with stm8s001 CICs
-add SWIM support for avr
Dumped/flashed MMX on SNES v3 boards.
created discrete_exp0_mapper_wr to try and write to mapper but not flash
for discrete boards but doesn't seem to work for some reason so commented
out for now.
Also the current build assumes that the mcu is able to over drive the
PRG-ROM output to select bank zero for initial bank table writting.
Seems to work, but may need to come up with write that applies to mapper
only and doesn't enable the PRG-ROM by keeping EXP0 low.
Need to work on having the scripts find the bank table.
