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.

D2K Arcade cartridge for Intellivision


from Elektronite Homepage:

One smart ape has escaped from his cage. Mario, the zookeeper, is in a real fix! The gorilla Darwin has captured a very special lady and made his way onto a construction site and up bewildering, unfinished structures and a veritable King Kong! Leap for your life over bouncing barrels, ride fast-moving platforms to dizzying heights, scurry under runaway springs, and avoid roaming flames and dangerous balls of gas as you make your way up. It will take not only Mario but one of his brothers Toni and Bruno to outsmart the big ape and return the girl to safety.

It’s TWO games in one! The first arcade game, PLUS a second game with five all NEW levels inspired by the arcade hit D2K: Jumpman Returns! 9 Screens in total!


  • New graphics and sound effects. Hear DK growl for the first time!
  • Separate high scores for Game 1 and Game 2. Perfect for high-scoring competitions!

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.

Unboxing & Assembly BitFixer PETdisk in Kit

September 28th, 2012 No comments
BitFixer PETdisk interface


The PETdisk is a new storage device, made by bitfixer, for the Commodore CBM / PET with an IEEE-488 port.

The system is in two parts. A datassette module that makes it possible to play “data” from a PC soundcard to the CBM / PET and play “data” from the CBM / PET to the PC. The IEEE-488 module has an SD card and a micro processor.

You can use the commands LOAD, SAVE and LOAD “$” to load or store data on the SD card. The device number can be changed with a help of a jumper. The USB cable is used to provide 5VDC from the datassette module to the IEEE-488 module.

For more informations,schematics,documentations and price of the kit please visit the site of the author.

The VC 314: Rasperry Pi in a Commodore 64

July 25th, 2012 No comments

Retrotext has made a interesting modding of a not working Commodore 64 with a Raspberry Pi.

For this project Retrotext has used the following things:

  • Commodore C64 with a working Keyboard.
  • Raspberry Pi
  • Keyrah USB interface.
  • 4-way USB port.
  • Three RCA connectors.
  • Ethernet and HDMI cable.
  • On/off Switch.
  • Power Supply and some other items.

The Commodore 64 runs under the Vice emulator (Linux) on the Raspberry Pi so we can play our favorites games.

About the Resperry Pi

The Raspberry Pi is a  small, inexpensive computer that is capable of running tasks like most other PCs, however it is smaller, a lot smaller in fact it measures  85.60mm x 53.98mm x 17mm , almost the size of a credit card and costs £25. It has an ARM11 chip at its heart, which finds its origins in early UK microcomputers, notably first in the Acorn Electron, the brain child of  Mk14, ZX80 and 81s’ Chris Currie and Austrian physicist Herman Hauser.

Unboxing SIO2SD Micro by Panos Santos

July 14th, 2012 1 comment
SIO2SD Micro (testing)


The SIO2SD is a device that allows you to load games/applications into any 8-bit Atari XL/XE computers via SIO interface from SD cards.

This version is like the original SIO2SD (based to latest schematic “version 2″) but in a smaller form with some improvements by Panos.

Panos improvements:

  • As for the cpu the latest “low consumption” ATMega32A microcontroller in smd form.
  • The 74LVC245 who guarantees good data transfer between the microcontroller and SDcard, in proper voltage levels also.
  • New 47nf capacitors for better button response.
  • Extra resistor and capacitor added in output of low dropout voltage regulator, for better voltage stability particularly at “no load” condition. As result of that is much higher reliability and compatibility with more SD cards.
  • New tactile switches with smooth feeling for more comfortable use.
  • Push on-Push off type SD connector.
