SD2Snes Firmware v0.1.7 (Beta/Preview 4) released

August 18th, 2015 No comments

Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Download: SD2Snes Firmware v0.1.7 Beta/Preview Rev 4 (427)

Full Changelog:

  • Prevent software from using uninitialized DMA ch.0 transfer to corrupt the stack (fixes Nightmare Busters)
  • Disable PPU region patching during the menu
  • MSU1: Stop audio playback on reset (fixes static buzzing noise in games after soft-resetting out of an MSU1 game)
  • Cx4: Add a switch for original/fast mode. “Original” mimics the Cx4 timing better (Megaman doesn’t die in MMX2 attract mode) whereas “Fast” uses a single CPU cycle for every instruction, improving frame rate when drawing polygons (rotating head in MMX2 intro).
  • Hide dot files and directories again (Regression in 0.1.7).
  • “Stealth Mode” for in-game hook memory area hides the memory region used by in-game routines from games. (Fixes Equinox, Lion King)
  • In-game hooks are a bit less intrusive in terms of CPU time, hopefully reducing glitches a bit with problematic games.
  • System Information screen shows file system usage on card.
  • Slow down DSPx a bit to better match original speed (should have no noticeable effect)
  • Font height is reduced by one pixel to increase readability (lines of text are more distinguishable). This has an effect on the font style so some might not like it…?
  • Background is greyed out when a window is active in foreground
  • Menu now uses the dynamic hierarchical menu system, with automatic calculation of window dimensions, etc. Not much of it can be seen at the moment due to the lack of menu entries.
  • Experimental SRAM mapping for Cx4
  • FPGA: adjust address sampling time for “end-of-cycle” events. Should help primarily with DSP1 glitches.
  • MSU1: initial volume now adheres to the latest spec (initial volume = 0) so it must be initialized by software to the desired level. This actually breaks my own example player I will post an updated version of it shortly.

SD2Snes Firmware v0.1.7 (Beta/Preview 3) released

October 19th, 2014 No comments

Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Full Changelog:

A minor update, mainly in the name of stability. This hopefully eliminates glitches unrelated to the in-game buttons on some consoles, e.g. Seiken Densetsu 3 rebooting intermittently or graphical glitches in DKC 2+3, that had been introduced with v0.1.7 preview 1.

  • Reintroduce more aggressive filtering for control and address lines from the SNES, previously removed after v0.1.6
  • Unify and centralize signal edge detection for all sub-units (e.g. S-RTC, MSU1, BSX, DSP etc.) instead of each unit having its own (slightly different) edge detection.
  • In-game controller scan has become slightly more time effective under certain circumstances (Auto Joypad Read enabled but no NMIs).
  • In-game hooks are now disabled for 10 seconds after loading or resetting a game to help certain games get past their boot screens. This will be configurable in the final.
  • Reconfigure the FPGA only when necessary on warm reset, speeding up “reset to sd2snes menu” by a couple hundred milliseconds.
  • Fix an MMIO access priority bug for DSPx.
  • Fix BS-X ROM detection for games with 2 startups left.
  • Fix directory browsing being broken after setting the clock.

SD2Snes Firmware v0.1.7 (Beta/Preview 2) released

September 26th, 2014 No comments

Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Full Changelog:

It addresses some issues reported with v0.1.7 preview (and some others).

  • Satellaview works again. BSX alters the original interrupt vectors at run time. The original interrupt vectors are now saved per hook call, not only once when loading the ROM.
  • In game buttons now work with MSU1, too.
  • Automatic hook method choosing: NMI is default but switched to IRQ when no NMIs are triggered. If both occur, NMI has priority. This should enable the in-game buttons for games that previously did nothing.
  • The hook routine saves some CPU time when auto joypad read is enabled by the game – it will just reuse the result instead of doing its own controller scanning. Also the controller is now only scanned every 8 frames. This helps alleviate some glitches, e.g. Secret of Mana now starts up correctly. There are still some glitches left which can’t be eliminated fully.
  • Auto region patching works again without having to delete the sd2snes.cfg.
  • BSX now emulates Type 1 memory packs instead of Type 2. Apparently the BSX BIOS is buggy with Type 2 packs when they contain HiROM games that are supposed to be run from PSRAM. So, at least Bomberman works now, and probably others too.
  • Fixed BSX PSRAM shadowing for HiROM.
  • Files and directories with “hidden” or “system” attributes are now actually hidden from the file browser.

SD2Snes Firmware v0.1.7 (Beta/Preview) released

September 19th, 2014 No comments

Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Full Changelog:

  • 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. ;)
  • 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.

In-game button mappings:

  • L+R+Select+Start = Reset game
  • L+R+Select+X = Reset to sd2snes menu
  • L+R+Start+B = Disable cheats
  • L+R+Start+A = Enable cheats
  • L+R+Start+Y = Kill in-game routines (in case they interfere with game operation).
  • L+R+Start+X = Temporarily kill in-game routines (~10 seconds – if you need to get past a glitch but don’t want to lose in-game buttons)

SD2Snes Firmware v0.1.7 status update

June 25th, 2014 No comments

SD2Snes Firmware v0.1.7 status update

Directly from the SD2Snes Homepage:

Here’s what I’ve been working on in the meantime:

  • More refactorings of the menu ROM. This will facilitate further UI development (sub-menus etc.)
  • NMI+IRQ hook routine – these are required for WRAM cheats and in-game reset. The latter is in working state as of now. I’d like some input on which key combinations would be desirable ;-) (some conflicts can arise with existing SNES mods, see below). There is now a dedicated memory area in FPGA block RAM mapped to $2a00-$2aff which is used for the hook routine and command exchange between a running game and the sd2snes main CPU.
  • Game loading handshake between SNES menu and sd2snes CPU – this is a technical prerequisite for error handling (such as missing supplementary files, write-protected SD Card, etc.)
  • 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. Also the sd2snes will retry saving until it works so you have the chance to swap out the SD Card etc.
  • “Screen saver” – 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.
  • Fixed 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))

To do for the upcoming release:

  • Cheat management – technical prerequisites for cheats (ROM+WRAM) are met, now to code the GUI for it…
  • Finish on-the-fly file browsing
  • Decide on key combinations for in-game functions. (en/disable cheats, kill cheat engine, reset game, reset to menu)

About key combinations:

I wanted to use combinations that don’t interfere with my SNES IGR mod. This mod uses L+R+Select in combination with Start, A, B, X, or Y to perform different operations. In that scenario I still had the four directional buttons left to put other functions on. However :D With borti4938′s release of the feature-enriched uIGR these are now taken.

So far this is my new proposal for key combinations (UPDATED 2014-06-24):

  • L+R+Select+Start = Reset game
  • L+R+Select+X = Reset to sd2snes menu
  • L+R+Start+B = Kill in-game routines (in case they interfere with game operation).
  • L+R+Start+A = Disable cheats
  • L+R+Start+Y = Enable cheats

Updated to reflect some of your suggestions. Already looks better to me. I steered clear of L+R+Start+X because it’s similar to L+R+Select+X. ;)

SD2Snes Tiny status update

Tiny status update of the SD2Snes Cartridge from Ikari

Directly from the SD2Snes Homepage:

So I’ve been getting a lot of questions pertaining to current progress, understandably. ;)

SuperFX is still crawling along, I’ve gotten a basic CPU core control unit and partial instruction decoder to work which can run test code in simulation fine, albeit limited. But it doesn’t deal with the different memory delays, stalling and parallelism yet; also the SNES interface, plot logic and other supplementary stuff are still missing.

The SuperFX uses pipelining which is a thing I haven’t fully understood yet, so that’s going to take some brain work and likely multiple complete rewrites of the CPU core. I’d rather not give an estimated time of completion for that at the moment… ;) Implementing pipelining properly is important because game code is laid out to take advantage of it and will not run correctly otherwise.

Besides the SuperFX, kogami has discovered a BS memory mapping bug, a regression that snuck into firmware 0.1.5 where I rewrote the BS memory mapping based on my own RE efforts. Also some graphical corruption has been found when using the “Run previous game” feature (Start button). I expect to make a bug fix / minor release addressing these issues (possibly others) in a couple of weeks.

SD2Snes Progress update

October 21st, 2012 No comments

Ikari want to make a bit of clarity of the future of the SD2Snes interface.

Directly from the SD2Snes Homepage:

Progress update & (rough) road map:

In the past weeks, amongst a number of smaller feature requests, I’ve been getting a lot of questions about SuperFX progress. I’ve even seen rumors spread about SuperFX support being cancelled. This is not the case.

SuperFX is the most complex core to implement to date, and it even took me several months to complete Cx4 support. That was before the public release of sd2snes, however, so less people noticed. Rest assured that SuperFX support is still in progress. It will take at least the rest of this year though.

To me, having existing features working properly takes priority. That’s why I’m addressing reported bugs and also minor feature requests which have been in the queue for quite long in parallel to working on SuperFX. I expect there to be 1-2 more releases before SuperFX support is introduced in v0.2.0, not counting critical bug fixes should need for them arise. Since people seem to get annoyed at my love for the Satellaview I’ll put off further work on that until after SuperFX.

There will be a v0.1.5 release shortly, which supports large SRAM properly, fixes sorting of long directory entries, fixes a glitch in SPC playback with S-APU consoles, works properly with non-standard controllers plugged in (e.g. Super Scope), and has more faithful BS-X memory mapping (<- actually finished a couple of weeks ago).

v0.1.6 will probably introduce proper SuperCIC support (allowing to select 50/60Hz from the menu) and maybe rudimentary cheat code support (ROM patching only). Both might be delayed to v0.2.0.

Keep in mind that while I’m continuing work on SuperFX support it helps do something else now and then.

SD2Snes Firmware v0.1.4 released

July 10th, 2012 No comments

It was released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom) by Ikari. The upgrade instructions can be found here.

Changelog:

  • SPC Player (contributed by necronomfive/blargg)
  • System Information screen now shows CPU/PPU revision (contributed by necronomfive)
  • Satellaview: basic data transmission packet support (makes some more games boot, thanks to LuigiBlood for assistance and sample data packets)
  • Number of supported files increased to 50000 per card / 16380 per directory.
  • Slight speedup of menu text rendering.
  • Reduce load time of menu.
  • Adjust Cx4 timing to be more faithful (Mega Man now defeats the boss in attract mode in Mega Man X2)
  • adapt ROM mirroring size to file size if header information is invalid (fixes Super Noah’s Ark 3D, possibly others)
  • MSU1 interface changes suggested by byuu:
    • Data offset 0 and audio track 0 are automatically requested on reset. This causes the busy flags to become 0 shortly after reset/startup.
    • $2000 bit 3 is now “audio error”, becomes valid after “audio busy” -> 0 set when an error occurred while preparing playback of the requested audio track write LED stays on when SRAM content changes constantly.
  • Fixes:
  • fix empty save files on FAT16 / incorrect free cluster count on FAT32.
  • correct directory sorting (force parent directory at top of list)
  • fix text corruption when entering a directory with a scrollable name.
  • fix files/dirs count in system information.
  • make ‘sd2snes’ directory hiding case-insensitive.
  • improve DAC I²S timing.
  • fix occasional palette corruption in menu.
  • fix SD clock glitch on ROM loading (occasional glitches/crashes)
  • fix memory write timing on ROM loading (occasional glitches/crashes)
  • fix SPI timing (ROMs not loading; System Information not working)
  • properly synchronize SNES control signals (occasional glitches/crashes)
  • fix floating IRQ output (occasional glitches/slowdowns)
