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.

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.

Quick overview of some Flash Cartridges (backup device) for Super Nintendo (Famicom/Snes), Megadrive (Genesis), Nintendo 64, Atari 2600.
Flash cartridges (backup device) used in this video:
- Everdrive-MD flash cartridge for Sega Megadrive (Genesis) with SD/MMC interface.
- EverDrive 64 backup device for Nintendo 64 with SD interface.
- SD2Snes backup device for Super Nintendo (Snes/Famicom) with SD interface.
- Harmony flash cartridge for Atari 2600 with SD interface.

The SD2Snes cartridge is a SD Card Cartridge for the Super Nintendo / Famicom / Snes.
This cartridge, unlike previous products such as the NeoFlash SNES Myth Cart, has more space inside the Xilinx Spartan FPGA to store code so in the future it is possible to support any special chip as long as it has been firmware updated with the latest code provided that support has been developed and implemented.
Xilinx Spartan FPGA Firmware updates can be done without any special hardware, again, unlike the NeoFlash product. You can put the firmware on an SD card and it will automatically find the file and allow you to flash it right in place.
This cartridge already supports the Capcom CX4 microchip which is used in both the Megaman/Rockman X2 and Megaman/Rockman X3 cartridges. NTSC/U/J and PAL/E ROMs will run without a hitch as well as the Megaman X3 Zero Mission ROM (with the latest firmware update which readdresses some of the memory mapping in code).
It also works with ALL DSP chips including third party vendors (DSP1A/B, DSP2, DSP3, and DSP4). SD Gundam GX and TopGear 3000 run as well as Dungeon Master and Pilotwings. All of these titles load in a fraction of a second and are fully playable. There is no difference between the gameplay of these ROMs using sd2snes than playing them on original cartridge hardware.
Features:
- SD/SDHC/SDXC support (tested up to 64GB; no exFAT support so SDXC cards must be reformatted using FAT32)
- High quality push-push memory card slot.
- Fast ROM loading (~9MB/s)
- Fast menu navigation.
- Directories are sorted automatically, no need for FAT sorting tools.
- High resolution menu (512×224) for adequate display of long file names.
- Real Time Clock.
- Supports ROM size up to 128MBit (96Mbit actually implemented)
- Automatic near-time SRAM saving to SD Card (while the game runs). Some limitations apply:
- near-time saving is switched to periodic saving when a game is found to use the SRAM as work RAM.
- Automatic saving is disabled when MSU1 is used. SRAM is saved on reset.
- Enhancement chip support (see below for implementation status)
- BS-X memory map / Satellaview base unit registers (clock)
- DSP1 / 1b
- DSP2
- DSP3
- DSP4
- ST-010
- Cx4
- MSU1 (Each supported enhancement chip can be used in conjunction with MSU1.)
- S-RTC
- SuperCIC key (SNES CIC clone):
- enables operation on unmodified consoles of all regions.
- supports software 50/60Hz switching on SuperCIC enhanced consoles only (to be performed by sd2snes firmware, not yet implemented there)
- Auto region patching: eliminates “This Game Pak is not designed…” messages regardless of 50/60Hz setting.
A few things that may be added via Firmware updates in the future:
- GSU-1/2 (SuperFX)
- Action Replay/Game Genie code support
- SPC7110
- and more…

The Altera USB-Blaster adapter interfaces a USB port on a host computer to an Altera FPGA mounted on a printed circuit board. The cable sends configuration data from the PC to a standard 10-pin header connected to the FPGA.
You can use the USB-Blaster adapter to iteratively download configuration data to a system during prototyping or to program data into the system during production.

The Everdrive is essentially an interface which allows your ageing console to communicate with an SD card. Using software loaded directly onto the device, the Everdrive boasts a simple menu which allows you to navigate your way around your SD card and load one of hundreds of ROMs into its flash memory. This takes only a few seconds and once the process is complete it’s as if you’ve slotted the original cartridge into your machine.
The Everdrive itself is manufactured in the Ukraine by a talented guy known as Krikzz. He only sends out the bare circuit board so you may want to cannibalize an existing cartridge to create a suitable case. Setting up the Everdrive is relatively straightforward; you simply format your SD card in FAT32 and then drop your ROMs into organised files. One thing you have to note is that each folder cannot have more than 512 items in it, so it’s a good idea to create a folder for each letter of the alphabet and then transfer the files into each.
The Everdrive can be ordered direct from its creator via his website or via resellers on various auction sites.

The Indivision AGA Mk2 A1200/4000T is the successor to the discontinued Indivision AGA 1200 flicker fixer. As the name suggests, the new version also supports the Amiga 4000T (not the A4000 desktop model, there’s the Indivision AGA Mk2 A4000/CD32 for use with that computer). Other Amiga models are not supported.
The Indivision AGA Mk2 support a DVI-I connector instead of the usual VGA socket. DVI-I provides digital as well as analog signals, so you can use modern TFT displays, older TFT displays with analog input or CRT monitors alike (the latter two with a VGA adapter).

1 Cents Atari 2600 Video Composite Mod: This very simple/cheap and functional mod adds a Video Composite output to the Atari 2600 console. I have shorted the five contacts Luma/Chroma and Sync for get a decent composite Video Signal. I have also cut a resistor (R55) to get better colors, for the Audio signal see the picture.
The Harmony Cartridge is a simple, affordable, time-saving, space-saving, hassle-free way to play hundreds of games on your Atari 2600 console.
Using a Harmony cartridge is easy. Just insert the Harmony cartridge into your console slot the same way you would with any ordinary Atari game cartridge. Put your favorite game binaries on an SD card, pop it into the Harmony Cartridge and you’re ready to go. Turn on the console, select the game you want to play from the list and start having fun.

Musicmax gives an demonstration about installing and the use of the Commodore c64 Kernal Multiload.
This device comes in two parts:
- One EPROM that replaces the original Kernal of the Commodore 64.
- A control-box that makes it possible to select and start an alternative Kernal.
In the video you can see that the SX-64, EXOS V3, JiffyDOS and the Cockroach Turbo ROM are being used.

SIO2Arduino is an Atari 8-bit (800/XL/XE) device emulator that runs on the Arduino platform. It currently emulates a single Atari 1050 disk drive (D1:) but there are plans to extend it to support multiple drives as well as other devices.
In its current state, SIO2Arduino allows you to put single and enhanced density Atari 8-bit disk images (ATR, XFD, XEX and many PRO and ATX) onto a microSD card and boot them on real Atari hardware.
