Firmware v1.11.0 beta 1

Firmware v1.11.0 beta 1

At long last I am starting to feel confident about this release. Due to the amount of features added and since a lot of time passed since the release of v1.10.3 I figured it might be wise to do a beta version first.

As such, use at your own peril. ;)

Download here: https://sd2snes.de/files/sd2snes_firmware_v1.11.0b1.zip

Features added:

  • [All] USB (usb2snes) support by RedGuy
  • [All] save state support (via USB/savestate2snes) by RedGuy
  • [All] stand-alone save state features by FURiOUS
  • [All] some compatibility improvements and optimizations for stand-alone save states by ikari_01
    • Add support for YAML list items for multiple savestate_fixes entries per game
    • Add support for simple bitwise operations on savestate_fixes patches
    • Add support for verbatim code execution on savestate_fixes patches – notably fixes Star Ocean (decompressed) save states (however the save state hook still needs CPU time optimization to prevent music glitches in Star Ocean.)
    • Add IRQ support on top of NMI for the save state hook – this enables save states on Out Of This World and possibly other games that only use IRQ. Also fixes controller input capture on a number of games so the game-specific input hacks could be eliminated.
    • Moved save state code outside of the USB hook area to make room for USB hook execution.
  • [All] SGB support by Redacted173.
  • [All] favorite games list by freelancer42

Fixes:

  • [All] Fixed data caching bug in MSU1 data extension which could cause wrong data to be streamed
  • [All] Savestates: do not try to capture data that is already in cartridge space anyway (e.g. SRAM). Fixes text distortion in Near’s Bahamut Lagoon translation when loading a state.
  • [All] Fixed YAML config parser to support comment signs after list start items
  • [All] Fixed SNES open-bus contamination (fixes sprite flickering in Near’s Bahamut Lagoon translation, certain speed runs that rely on open bus behaviour)
  • [All] (hopefully) fixed rapid data line toggling sometimes resulting in address line glitches, causing random crashes in extreme cases, and occasional garbled graphics on SMRPG among others
  • [All] Fixed data integrity problems when loading BSX games

Usage / Testing Notes:

SGB

Note: SGB support requires at least two additional supplementary files:

  • sgb#_boot.bin: The internal boot ROM of the SGB-CPU
  • sgb#_snes.bin: the SGB BIOS ROM that runs on the SNES when you use the SGB.
  • ‘#’ in the filename is replaced with a 1 or 2 depending on the BIOS version you select in the SGB Settings menu, e.g. if you select BIOS version 1 it will look for sgb1_boot.bin / sgb1_snes.bin.
  • The status of the required files can be viewed on the System Information screen.
  • SGB In-game hooks and save states only work when the files match known samples.
  • Please also refer to README.SGB.txt in the sd2snes folder.

Save States

Important notes:

  1. Save states are currently only available on games that do not use expansion chips.
  2. Save states are not currently expected to be fully compatible with 100% of games. If you find a game that does not work with save states, please report – I will be working to improve compatibility.
  3. Save states do not include the state of the SNES’s audio subsystem (APU) due to technical restrictions of the SNES hardware design. Therefore music, sound effects, etc. will remain unchanged after loading a state. Some games maintain close synchronisation between game logic and APU state, requiring (usually) a 1-byte patch to bring them up to date with the APU. These patches are maintained in the file savestate_fixes.yml. For anyone proficient in debugging SNES games who wants to add their own patches, possible formats for patches are outlined in the file.
  4. If you succeed in making a save state fix patch for a new game, please share them :)
  5. To use standalone (non-USB) in-game save states, “In-game hook” must be enabled in the “In-game Settings” menu, and “In-game savestates” must be enabled in the “Savestates Settings” menu.
  6. Please also refer to README.Savestates.FURiOUS.md in the sd2snes folder.

When the “Savestate slots” option is enabled, one of four save state slots can be selected in-game using a button combination.

“Load delay (frames)” is used to set a delay after loading a save state before returning control to the game. This gives you some time to let go of the save state buttons and get your fingers back into the normal playing position.

Save states can be saved and loaded in-game using button combinations on controller 1:

ButtonsFunction
Start+LLoad state
Start+RSave state
Select+D-PadSelect save state slot

Using the D-pad one of four save state slots may be selected (Default: Slot 1):

D-pad directionSlot number
UpSlot 1
RightSlot 2
DownSlot 3
LeftSlot 4

Favorites List

The favorites list can be viewed from the Main Menu (X button).

To add a game to the favorites list, simply navigate to it in the file browser and press Y to pull up a context menu that displays actions that can be performed on the current selection. (Right now this menu only contains a single entry – “Add to favorites”.

To remove a game from the favorites list, open the “Favorite games” list from the Main Menu, select the entry to remove, and again use the context menu (Y button) and select “Remove from favorites”.

On a personal note

I regret to say that this release is overshadowed by a recent tragic event.

Near (formerly known as byuu) has passed away on June 27, 2021. To this day I cannot grasp the reality of it all.

On top of his outstanding contributions to the emulation and ROM hacking scene, Near was always a source of inspiration and creativity. Although there were not many occasions on which we worked together, whenever we did it was a blast and put a smile on my face. Near came up with the MSU-1 spec, I made the first hardware implementation of it – thereby turning the sd2snes into a marketable design in the first place. I made a custom SuperCIC specifically for his cartridge dumping project back in 2010. We discovered and got to the bottom of various SNES hardware quirks together. “Professional” endeavours aside, he also encouraged me in getting to know myself better.

I owe Near a lot, and wish I could have thanked him in person one day. I will miss him. A lot.

To honor Near’s memory this release contains a very brief farewell message that will be shown for a few seconds on first boot only (provided that your SD card is not write protected). I hope that you find this tolerable; it was important to me.

Looking forward to that farewell message. I just wished we knew how bad things were that we could’ve tried to help them and show them that they weren’t alone.

RIP near

R.I.P. Near, and thankyou.

Sounds like a fitting tribute, looking forward to seeing it on the first boot. Thanks for your tireless effort.

Many thanks go to Near for his contributions to the scene. He was responsible for so much behind the scenes of the retro gaming community. He must have meant a lot to you to spend the time to develop that farewell message.

This is a beautiful release. Thank you.

Matt was here, after pressing F5 every 5 minutes for 2 years! :D
Thank you very much for this new release and the long writeup!

I was and am very sad about Near as well. Thanks for including a memento for him, I think nobody will be bothered if this stays forever. :-)

Thks for great work Team Project SD2SNES

What a crazy release! I can only imagine the hours you and others have put in for such features. Thank you very much ikari_01.

I have yet to try the firmware and see the message about Near, but I can assure you this is very much appropriate and tolerable. Given everything they’ve done for the Super Nintendo fans around the world, all sd2snes users should know and appreciate their work. <3

Excellent! Thanks for your hard work. RIP Near.

I just tried out the beta on my SD2SNES Pro and Super NT. Many games won’t load right now and I’m getting the same black screen with Game Boy games, system information shows everything is ok with the extra files I put in. I can’t see a pattern since some SNES games do work, but I’ve switched back to the previous version of the firmware without issue.

That firmware seems to be working well. Not having any issues launching games with all the default settings in it. I’ll try the Beta firmware again without any modifications.

It looks like it’s caused by my custom menu files for the last firmware I was using. Everything works fine if I use the original menu files.

Hi ikari, I tried the new firmware. But unfortunately the sd2snes freezes after booting up. I tried to download and copy the firmware again to the SD card. But no success, older firmware works, this one freezes after booting.

Hi, thanks for the reply. I don’t use a custom theme. The furious firmware works fine.

try to start with a fresh firmware folder, without the furious files :-)

Hi Ikari! No problems on my French Super Nintendo. I haven’t tried the new features yet, but otherwise nothing to say. Great job as always, keep it up, so we can relive our younger years with this great console. And thought for Near who left us way too early. You were right to put a message at the start, I think it fades a bit too quickly. Nice gesture in any case.

Thank you (and everyone else) for your continued work on this release!

RIP Near, thank you for all the work you did

[…] O firmware 1.11.0 beta 1 para o SD2SNES, SD2SNES Pro e FXPAK Pro pode ser baixado no site oficial. […]

thank you for the effort you put into still making updates! works great for me, my set up is a fxpak pro with custom theme (updated my theme to the latest version) and super nt. i use save states often and have had no issues at all so far. i recommend users remap the save and load state buttons to new ones that dont include start/pause by editing your config.yml file, because it results in the music being preserved when they are used with games where pausing silences in game music.

doesnt work on my sfc. after startin the sd2snes is freezing. older firmware works

An exciting update for my fxpak pro. This combines the furious firmware, with plug and play support for QUsb2Snes, fixes bugs and adds a favorites menu. It’s truly exciting and stable. I did get the special chips data files from the furious firmware folder.
Rip Near (byuu) and I think this farewell message should remain. Maybe make it being displayed 5 seconds longer. Once the onscreen menu from the OSCC disappears you only have a second or two to read the farewell message.

Hello Ikari, First, thank you for sharing your feelings about Near. Of course I don’t know the guy, but I always feel sad when someone pass away. I’m sure your message will not be intrusive. What about writing a permanent page accessible from the menu, where you’ll thank people that helped the project? Second, I’m once again amazed by the amount of content that just’ve been added to SD2SNES. When I furious’s version, I was wowed by save states and SGB support, two features I didn’t think would be possible. Two bad I don’t know someone IRL to share the… Read more »

Save states in Super Ghouls ‘n’ Ghosts still have issues. Whenever I load, I lose the sound. Usually I still have the music but no sound effects. Sometimes It’s totally silent.
I have this behavior with non patched PAL version, and also with patched MSU1 US version.
Save/load states works fine with a few other games I could test (i.e. Zombies ate my Neighbors, Parodius 2, Super Castlevania IV)

It works :)
To be precise, thanks to your code I keep all sounds with PAL rom. I also tried and test US version (shame on me not to have tested that before).
Then I figured out the checksum for my “restoration + MSU1” patched rom, fixed it somehow, and added it to that yml file. It ALSO works :)
Now I’ll be able to do that damn second quest with that great metal soundtracks from Kurrono. It as frozen in hell! (aka Super Ghouls’n’ Ghost, third level)

So, with this update, is there anything different to setting this up with the auto tracking feature for Link to the Past in emotracker? Been trying to get it going, and it’s not happening.

Fantastic. It works! Didn’t realize my Emotracker was out of date. Checking for updates said I was up to date. Thank you!!

As an addition: I can’t get GameBoy stuff to boot past black screen either. Menu says SGB2 stuff is OK. As far as I know I followed directions properly. Also tried the unofficial firmware thing you mentioned earlier with no luck.

Disregard my previous comment about GB. I renamed all the extensions to be lower case and now things are all good.

By the way, are there any chances that save states ever works with chip enhanced roms?

Hi Ikari! Thank you so much for the amazing feat of engineering and what a great tribute to Near who devoted his life to SNES preservation. Kirby’s Dreamland 3 is now working on fully recapped early Super Famicom CPU/PPU1/PPU2: 1/1/1 and SD2SNES. The game was randomly crashing on every previous firmware. Upon further testing it was noticed that Actraiser2 is acting up on previously mentioned system. The game freezes and unfreezes constantly, there are severe graphical glitches which are very apparent right after launching the game and the game usually crashes in one minute. The last known good configuration for… Read more »

I have just tested this version and everything seems to run perfect. Great job and very nice the inclusion of Super Game Boy :)

Hello ikari,i have loading problem with starfox rev2 rom,my snes crash on first level in hangar
sd2snes_v1.10.3-frs-v12 no problem with this firmware

What’s the hashes for the SGB1 files? The ones I’ve tried work but all give a mismatch error.

Hi Ikari.
Thank you, one again, for all your work/
I did think abouy you and about the scene when i heard about this sad news.
Thank you to share your feelings with us.

RIP Near.

I’m sorry for your loss and for the people who knew him. It sounds like a lot of gamers owe him a lot of thanks. Thank you for sharing your thoughts, and I feel the farewell message is absolutely appropriate. Have a good one.

The readme just gives file hashes for SBG2 roms, not SGB1 and does not mention that the SGB1 is even compatible, yet here it states it is.

Is there any step needed to enable the USB port?
I tried the beta firmware and my linux computer does not see the sd2snes.
lsusb does not show any new device when I start / connect the sd2snes.
I checked the cables and connectors and they seem to work ok.

Thanks!

I have it working now. The cable I used first was not working correctly.
Thanks!

Thank you very much for resuming work on SD2SNES firmware! Are there plans to add support for the special enhancement chip SPC7110?
Far East of Eden: Tengai Makyou Zero is one of the best looking and interesting games on the SNES and is sorely lacking on SD2SNES.

Thank you for all the hard work you do with these updates!

Hello Ikari, I’ve tried this beta, and whenever I try to use save states, the game goes to a black screen. I tried the Furious firmware and that works fine, but I would like to use this beta. Any advice?

black screen can happen if you load state without a state saved. incidentally if you are used to the previous furious firmware the button bindings for save and load states have been reversed (they can be changed back by editing your config.yml file if you want). i would love to see a future update include on screen text that indicates your current save slot and if it was loaded or saved like many emulators do when loading and saving. as i often forget which slot im using after awhile and it would clear up any confusion.

Thanks for the update! I’m not sure if anyone else has ever asked this – but is there any chance to implement the ability to delete games from within the menu list? The Mega Ever Drive PRO for Mega Drive allows this, and I find it exceedingly useful for trimming my games list as I finish games, or play titles which I dislike and have no intention of playing again.
