Hoxs64 written by David Horrocks is a Commodore 64 emulator for Microsoft Windows 2K/XP/Vista/Seven (DirectX 9+)
The emulator substantially reproduces this legacy machine in minute detail.
Changelog (1.0.12.0 -> 1.0.16.0):
- Prevent memory buffer overflow error when mounting G64 disk files that contain tracks that are longer than 7928 bytes. Allow arbitrary length G64 track data to be scaled to the emulated disk.
- Fixed G64 file header track size sanity check.
- Added VIA6522 shift register emulation to support raw captured VMAX4 loaders.
- CIA Time Of Day emulation accuracy improvement.

Firmware upgrades for THEC64 Mini provide new features and/or correct any technical issues.
We always recommend that you use the latest version of the firmware.
Version 1.2.0 – Changes:
- Adds a complete new game for free to the GAMES CAROUSEL! Galencia for the Mini is licensed from Jay Aldred and is the winner of the Reset64 Magazine 2017 Commodore 64 Game of the Year Award
- Introduces the Virtual Joystick. You can now select all options on THEC64 Mini and even play games just using a USB keyboard. See Virtual Joystick for further information
- Improves the File Loader to allow multiple programs to be configured at once. See Setting a Default Configuration for Multiple Programs for further information
- Remembers the mute state of the CAROUSEL music between reboots
- Improves the general performance of THEC64 Mini screens and menus
Note:
Galencia is the winner of the Reset64 Magazine 2017 Commodore 64 Game of the Year Award. It is a colourful, highly polished, Galaga inspired single-screen shoot-em-up.
Jay has worked really hard to produce a special version of Galencia just for THEC64 Mini and its 720p display, and it makes maximum use of the upper and lower borders for graphics, right up to the edge of the screen! Be aware however, that some HD TVs might crop some of these border graphics when displaying the 720p image. This is not a fault with Galencia or the Mini and we recommend that you refer to your TV settings.
Please be aware there is currently a 256 item limit (files and/or folders) to assist improved USB memory stick performance.

Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.
Changelog:
- SA-1 support by RedGuy! Big thanks to RedGuy again :) This was a really tight fit for the FPGA so there’s a little catch – MSU1 is not available for SA-1 games.
- Also from RedGuy comes partial SRAM detection for some known games (SuperFX & SA-1). This calculates a ROM CRC and chooses to monitor only specific regions in cartridge RAM for changes. This enables automatic saving without having to resort to periodic saving, reducing wear on the SD card.
- SNES CPU <-> PPU clock phase alignment. This is a long standing issue on a sub-CPU-cycle base inside the SNES. HDMA to certain registers can cause flickering sprite slabs to appear when CPU and PPU are out of phase after a cart-side reset (which does not reset the PPUs). This fixes the notorious flickering of characters with the giant frog attack in Chrono Trigger, sprites in Kirby Super Star, characters behind the text box in Star Ocean, and probably more. See https://github.com/RedGuyyyy/sd2snes/issues/6 for technical details.
- Added an option to always go back to menu on reset, regardless of whether it’s a short or long reset.
- LED brightness setting (16 levels)
- Added an option to choose whether you want to start a game with or without cheats enabled (of those that are marked as enabled in the YAML file). You can enable / disable them later using the L+R+Start+A / L+R+Start+B button combinations if you have in-game buttons enabled.
- Disable Satellaview emulation when a real Satellaview base unit is detected to avoid bus fighting and facilitate Satellaview development.
- System Information now shows the currently effective video mode (50 or 60 Hz).
- Fixes:
- Control signal edges are detected a bit earlier, improving stability on some consoles (Github Issues)
- Fix timing of auto region patching. This should solve cross-issues with Super Scope games because they rely on the same register that is also used to read the console region.
- Fix brightness patching / limiting for games that use HDMA to alter the brightness register. (e.g. Star Fox)
- Fix an occasional imaginary access cycle carried out by the FPGA after reconfiguration. This fixes lockups when loading games with dedicated FPGA files, i.e. SuperFX, SA-1, OBC-1.
- Fix SuperCIC pair mode entry for consoles with ≤ 3.072MHz CIC clock (notably GPM revisions). (Github Issue)
- S-RTC register state is reset when the console is reset.

This Commodore Amiga 600 is arrived in laboratory in immaculate state still with the warranty sticker.
Immediately after the disassembly i have immediately noticed that were are several problems of acid released from the capacitors and dirty that affected this poor Amiga 600 and its Floppy Drive.
A decoupling capacitor it’s exploded with a pit on the PCB side, solved this problem i started to replace all the electrolytic capacitors and to clean the pcb with specific products.
After the replacement of the electrolytic capacitors, i have tried to turn on the amiga that apparently worked, shame about the distorted sound and the floppy drive that read 1 time of 100.
I had to replace the electrolyte capacitor on the Floppy Drive and soon after i looked for the fault of the audio problem that 99% is always the usual LF374.
In this case it was not only LF374 but also a 10ohm resistor that did not let the +12v to the LF374 and a short-circuited ceramic decoupling capacitor.
Components that have been replaced:
- IC LF374 substituted with a fully compatible TL084C (U15)
- 10Ohm resistor (R301)
- 330nF capacitor (C301)
- 330nF capacitor (C41)
Unfortunately the welding of the LF374 did not come very well how i like to do it but the pad are destroyed and corroded by the acid and they were about to detach, indeed the pad of the pin 2 of the LF374 was really detached, that’s why the pin 1 and 2 of the IC LF374 are connected together, they were connected via the pad.
I leave you to the photos and the video.

The Commodore-SX64 keyboard after some time isnt’t responding anymore (all or some keys). In this case, the keyboard needs some cleaning and repair.
First of all you have to disassembly the keyboard housing, pay particular attention to the screws, this plastic is very old and not of a good quality, it breaks only if you look it.
Gently remove the membrane and clean with alcohol all the metal contacts on the keyboard pcb and also clean all the contact pads on the membrane without alcohol.
Next i took some graphite in cream (Keypad Fix) to reconstruct the pads on the membrane by simply applying a very fine layer of graphite on the contacts.

This monitor although fully functional in the video section, was missing audio. The integrated circuit of amplifying sound (TDA 2611A) was not powered.
The problem was a broken pcb track (see photo), solved this problem the sound is back.

I received this small Black and White CRT monitor from a friend, Ciro Barile of TI-99 Italian User Club, this monitor was used as a video intercom and i didn’t know the power supply voltage, the pinout but especially if it worked.
Found the pinout and the power supply voltage i saw the image turned upside down, this because the monitor could be hooked both from top and from bottom, nothing could be easier it was enough to change the deflection yoke connector on the motherboard to flip the image.
I drilled two holes on the back of the case to facilitate access to the composite video input and power supply (12v 2A).
Pinout:
- RED (Video)
- GREEN (Ground)
- BLACK (Positive)
- BROWN (Ground)

Jean-François DEL NERO (who’s behind the HxC SD Floppy Emulator) recently has released a version of the HxC emulator firmware that is compatible with the STM32 chip used in the Gotek floppy emulators.
This means that the great functionality of the HxC SD emulator is now available on cheaper and more widely available hardware.
The bootloader to convert the Gotek floppy drive in HxC compatible must be purchased on the website HXC 2001 by sending an email to Jean-François DEL NERO. The price of the bootloader is one-off 10 Euro per Gotek that you want to update. Future updates of the software are free and can be made from a USB stick
The HXC Usb (Gotek) firmware supports: 
+ many more….
