What is DiagROM?
DiagROM is a diagnostic tool for the amiga computers.
And it is to be used on defective machines, trying to help no-boot situations etc.
You simply replace the Kickstart roms in the Amiga with the DiagROM. and when poweron. your Amiga will start a diagnostic software. It will try to dump info on the serialport (and actual menus etc aswell) while also trying on the screen.
Changelog:
WOW This is a long time since I updated this. And lets be honest. I have forgot what i have changed.
BUT one thing I just been thinking. I have bumped the versionnumber in the wrong “end”.. so as I am working on a new init-routine. I consider this is the “stable” one.
So I bump the serialnumber to 1.2.1. I have been too busy with hardware so I must confess I haven’t coded so much on DiagROM. I have made some minor bugfixes etc.
I must still warn that if a routine is experimental you cannot really trust the tests.
Anyway in hope for the best in the future. the “daily” will for a while be a little “jumpy” while I get the new init working. This should be useful meanwhile.

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….

A new firmware update for the ARM2SiD has been released by Nobomi.
News features and fixes in FW 3.7:
- Compared to version 3.6, only marginal changes, added reading of OSC3 and ENV3 registers to the third SID emulation.
- Simplified user interface for the update application.
- Compared to version 3.5, a quick response in stereo mode was added (when using a second socket), the dual-mono mode is activated without timeout when both socket is addressed in the same time.
- Also upper addresses mapping is fixed in the update (sometimes misaligned address detection in the update application).
- Corrected bug in bootloader. If user tried an update with SFX only mode configured, the ARM2SID stuck in the bootloader and was not possible to update it on a user side. Factory update was needed. New updater disables the SFX mode, as well as patches the bootloader to prevent problems in a future.
