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.

The Commodore 4040 is the replacement for the previous models 2040 (USA) and 3040 (Europe). It’s a dual drive 5¼” floppy disk subsystem for Commodore International computers. It uses a wide case form, and uses the IEEE-488 interface common to Commodore PET/CBM computers.
These drive models use a similar single density, single side floppy data storage format to that used by the Commodore 1541 drive, but with a slightly different data marker indicating which model originally formatted the disk. The low-level disk format was similar enough to allow reading between models, but different enough that one series of drive models could not reliably write to disks formatted with one of the other model series.

I have adapted a power supply Cisco (P/N 34-0874-01) to be used with the Home Computer Amstrad CPC 6128/664 that use two voltages +5v and +12v (pinout). If you want to use this computer without the original monitor the only way is use a external power supply.
The photo speak for themselves, the modification is very simple. The only thing that i want to say, maybe not everyone knows it, the Cisco power supplies uses the STANDBY remotely, you need to connect together the ROF line with the one of two RTN (GND).
I have also added a third cable in case you want to use an external Floppy Drive.

The HxC Floppy Drive Emulator is a software and hardware system created by jfdn aka Jeff.
The aim of this project is to replace the floppy disk drive by an electronic device emulating the floppy disk drive (list of supported Computer/Hardware).
There are two differents emulators:
- A USB version which allows to connect the floppy disk drive interface of the computer to a PC via a USB cable.
- A SDCARD version which allows to emulate floppy disks which images are stored in a SDCARD.
Release notes for the HxCFloppyEmulator software v2.0.26.0:
- New Loader : PC Magazine (FLP) file format support added.
- GUI – Track viewer window : Track editing functionality added, internal sanity check added.
- libhxcfe : Casio FZF loader -> non sector-aligned file image size issue corrected.
- libhxcfe : Generic flux stream analyzer enhanced – Track encoding & RPM correctly reported.
- Batch converter : Now use the folder name for the output filename while converting KF stream files (raw).
- FAT12 Disk Browser: PC98 FAT disk support enhanced, free space reporting corrected.
- Raw Loader – Predefined raw formats added (XML) :
- Logical Interchange Format (LIF) 3″1/2 264KB (single side).
- Logical Interchange Format (LIF) 3″1/2 616KB (double side).
- Logical Interchange Format (LIF) 3″1/2 1232KB (HD).
- Logical Interchange Format (LIF) 5″1/4 264KB.

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.

Repair Commodore Amiga 3000 Motherboard with Battery leakage
There was once a motherboard of an Amiga 3000/25 devastated of the Battery acid where missings all the socketed components and others are unsoldered and recovered for other things.
The situation was not exactly the best one, in other words … was going into the box of spare parts.
I made the impossible, i have cleaned, scraped and rebuilt many tracks of the pcb corroded by the battery acid and i must say that with lot of patience i have repaired the motherboard giving a new life to this Amiga 3000/25 that he had no many chance to come back to work
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)
