Firmware v0.1.7 preview

Firmware v0.1.7 preview

NOTE: Satellaview is broken at the moment because it doesn’t work with the NMI vector patching. I’m working on it.
At last here’s the v0.1.7 preview. Cx4 blew up in my face when I tried to insert the cheat/in-game hook engine and ended up taking days to get working. :|
Here’s what’s new (mostly copied from the status post):

  • In-game button combinations are in effect. See the table below for the key mapping. Note that some games show glitches with the in-game functions in place. I added an additional feature to temporarily disable them in case of game glitches (e.g. Secret of Mana hangs at the Squaresoft logo, displaying only garbage). I’m not entirely happy with the button choice but it will do for now. ;)
  • When running a game from the recent games list, the selected entry is now moved to top of the list.
  • LED blink codes for file system errors – e.g. in case the SRM file cannot be saved this will tell you that something’s gone wrong. The blink codes are yet to be listed.
  • Also the sd2snes will retry saving until it works so you have the chance to swap out the SD Card. In that case the directory structure must be present where the sd2snes expects to save the file.
  • “Screen saver” – in the menu, the screen is darkened after some idle time to reduce wear on CRT and plasma screens.
  • Memory sharing between SNES and the sd2snes CPU is greatly simplified (The FSM is reduced to only 5 states instead of 18) and timing is more relaxed. This should help with stability on a wider range of consoles.
  • On-the-fly file browsing. Also shows a little “loading…” window when loading directories/files.
  • Windows are now blue so they stick out better in front of yellow directory listings.
  • Cx4 data ROM is now embedded in the FPGA configuration – no more need for the external file cx4.bin.
  • Initial Satellaview clock is back to 18:00:00 from 18:05:30.
  • SD cards can be hotswapped. Currently there is no automatic refresh of the file list so tapping reset on the SNES or changing the directory is necessary to get the new contents.
  • The status line is moved upward a few pixels so hopefully it doesn’t get eaten by overscan.
  • Navigation: When scrolling page-wise with the right D-pad arrow, the end of the file list is now aligned to the bottom of the screen.
  • Navigation: The shoulder buttons can be used to jump to the beginning/end of a directory listing.
  • Bugfix: some compatibility issues with a number of games. (Super Play Action Football (S-RTC interference), GP1 Part II (WRAM initialization), Human Grand Prix (mapper detection bug))
  • Bugfix: properly initialize FPGA state machine (on some consoles the menu failed to start at all)

v0.1.7 final will contain menu items for various configuration settings and a cheat interface.
Please let me know if any games are broken that worked before, even with the in-game functions disabled.

In-game button mappings:

ButtonsFunction
L+R+Select+StartReset game
L+R+Select+XReset to sd2snes menu
L+R+Start+BDisable cheats
L+R+Start+AEnable cheats
L+R+Start+YPermanently disable in-game hooks (in case they interfere with game operation).
L+R+Start+XTemporarily disable in-game hooks (~10 seconds - if you need to get past a glitch but don't want to lose in-game buttons)

Yippi!!!

(First Reply :D)

Falenye

Awsome! Thanks alot ikari :-)

borti4938

Great work on that :D Just tested the Button combinations so far and works great for now (just 5 min of testing) ^^ Will let you know if I find anything…

BTW: First reply xD I have seen the preview coming up on GitHub

borti4938

nooo – not the first one… However – you forgot to mention the new sorting strategy of the last 10 games played which is much better than the one in v0.1.6

Dragun

That update screwed up everything. My screen has a bunch of garbage on it now with the menu in the background; reverting to 1.6.

Dragun

Fixed – I was using one of the custom menu.bin files, replaced it with file in zip – all is good now.

Renaud

I will test it and leave reply if I find someting
thank you so much ikari

Ken

Dude, this is sooo Cool!!

Ken

My Rom of Star Ocean doesn’t seem to work. I had just gotten it to work with v0.1.6 using that (SDD-1 hack) patch. That sucks.

Renaud

Good Job Ken I will say the same !

Anyway Ikari, this preview is a really great improvement

Ken

Awesome bro!

frigusoris

Amazing work! So far everything is great. Thanks again and I look forward to future updates.

Suggestion for hot-swap saving. If directory structure is not found on the new as in the previous card, revert to saving in the root of the card.

Greatfunky

It could be nice to get a “On-the-fly file browsing” enable/disable option in a future release because it take a time to each time open a folder when you have a lots of roms Inside ( especially when you didn’t add new roms frequently like me ^_^! )
Everything else is pure happiness …
Thank you Ikari!

Tuff*Gong

Awesome Ikari! Really great work, I liked it when the sd2snes folder was hidden as I already have like 6 folders on the root of the SD card.

Tuff*Gong

Nevermind, I am guessing this is due to the fact that it does on the fly browsing now instead of writing the folders do a database.

Renaud

Hi Ikari
i got some characters issues with this menu
i can’t navigate, because it’s some random letters
http://manuloewe.de/snestuff/sd2snes/menu_0.1.6_tsr.bin

if i put your menu.bin, everything is fine :)
i will test the update firmware for star ocean

TSR

Renaud, the menu changed a little bit so Ramsis’ menus aren’t compatible anymore.
We can only hope for now that Ramsis would update them for the new 1.7 format ^^;

… I’m pretty much occupied by my own SNES project(s) right now, but I’ll see what I can do (as always). ^^

TSR

Great, thank you!

Dragun

The previously hidden folders are appearing now.

You probably have to manually mark them as hidden (if you want to) using your computer. ;)

Antonioks

Ikari would be nice if you could use the cheats as .cht, .pat this would facilitate the use of the lot and have the cheats Mega Everdrive and put the codes it could never do any more work on emulators and the codes work.

Tuff*Gong

That would be so awesome ikari!

Great work, ikari! :D

But is it just me or does the console reset/IRQ hooking stuff only work in a few selected games? It doesn’t work for me in Star Ocean (96 Mbit, tested with the fixed firmware), nor in any MSU-enhanced game.

Also, I’d suggest adding an option to completely disable the new IRQ hooking routines from within the menu (which would allow me to watch Secret of Mana’s gorgeous opening without any hectical button mashing). :D

Thanks!
Ramsis

TheRetromancer

Noticed that with 0.1.7 preview, no MSU-enhanced games are compatible with the reset/processing button combos. Tried it on Zelda 3 and SM:Oddysey

Renaud

It looks like Tales of phantasia can’t be stopped with L+R+SELECT+X or L+R+SELECT+START
I tried it on a translate rom..

Thanks for the pre-release firmware. I’ll test it on my SNES.
A minor question, what is the USB port on the top of the SD2SNES used for? Potential loading ROMs via USB? Or is it a way to update the SD Card Filesystem while the board is not in use?

Just noticed the Stellaview broken message in the post. Whoops. Rolling back to 0.16… I might be using the wrong BS-X BIOS, but when I’m trying to run some BS Mario USA Power Challenge (the World 1/2/3/4 ROMs), I get a black screen on 0.16. The BS-X BIOS file was actually a 1024kb SMC file (got it from the website that has a picture of a beach and a palm tree that starts with “Emu” ;) ) that I renamed to “bsxbios.bin” in my SD Card’s sd2snes folder. I’m wondering if i got a bad dump or I’m doing something… Read more »

Thanks ikari for the great update. I have found that the firemen won’t load past the human interactive logo

Jason

Hello ikari. Thanks for the great update preview. Here are the bugs I’ve found so far. All tested on standard NTSC-U SNES, CPU 2 PPU1 1 PPU2 3. Super Punch-Out: Anti-piracy screens now show up. Game works fine in 0.1.6. The following games are glitchy unless in-games routines are disabled. The Firemen: Hangs at Human logo. Goof Troop: Sprites sometimes turn invisible. SimCity: Title screen if garbled. Tetris & Dr. Mario: Tetris blocks are all black. Yoshi’s Cookie: BSP logo is glitchy. The following games don’t work with the in-game button combination. Marvel Super Heroes in War of the Gems… Read more »

I know this may be a silly question but will there be an option to shut off all these combination mapping buttons in v1.7 final? Looks like these mappings are wreaking havoc on a lot of games.

Ken

I look forward to being able to change the background of the start up menu (It just doesn’t look very “SNES” to me) It would be really cool if we could choose different themes for the menu, like Metroid, Zelda etc. Of course that’s all just nitpicking at this point. I’m happy with my purchase.

cheema

Gave this a quick go today – I love the idea of sending out a preview firmware like this so that people can report back on bugs from the changes. Great work but already implementing the timing changes :D and also the in game reset function is pretty cool for lazy people like me!

Thanks again, looking forward to the final release – if I notice any bugs I’ll let you know

I observed a quite strange problem yesterday.
The IGR-PIC acts quasi randomly. The keymappings do not work properly.
Especially with PAL-Roms in 50hz. E.g., Sunset Riders resets in 50hz using Right + Down + Y. With firmware v0.1.6 and also the original games everthing work well.
I tried different reading strategies (polling & interrupting) for the PIC as well as different PIC (16F630, 16F684, 16F688).

borti4938

The IGR starts to read the joypad after the data latch came high and back down. So the time the IGR needed to compare button values is not a big deal. The main problem is the duration of impulse chain after the data latch. The duration of the manual controller scan might be to short. Hence, the IGR-PIC reads data throughout two or more joypad reads as long as he has detected twelve impulses. The stored data is not in the expected order anymore. Is there a chance to make the manual controller read more similar to the auto joypad… Read more »

Thank you :)

daph

Thank you for this 1.7 preview release! I really appreciate your work on the SD2SNES. However on this new release, when playing Chrono Trigger and going about the menu screen, the graphics glitch for a second between transition. If I revert back to 1.4, it works perfectly.

keropi

Thanks for the update… do the in-game-keys conflict with the IGR PIC? I have it along the supercic on a custom pcb … it is working great as is without any game problems btw

Anon

Is chrono trigger working for anyone? Seems to lock up my system completely if I press A in the opening.

bidou

hello

you have a link for the latest Firmware v0.1.7 preview ? thanks :) the region patcher is broken on 0.1.7

Konrad

Hey Ikari. My sd2snes keeps blinking the red led for 10 times each cycle with a pause in between. what does it mean?
