In general it is not possible to convert an MTX file to WAV format. WAV files are divided into a number of blocks, each with its own lead-in. The MTX file format does not record the start and end of these blocks. However a standard BASIC file typically consists of four blocks: A short block giving t...

The only game I can remember playing any significant amount is Toado . The other games I have copies of are: Draughts - I don't remember ever actually playing this. Chess - I think this completely trounced me the first time I played it, and I probably never went back. Snowball (Level 9 text adventur...

I have now done some testing on a Pico.

The issue was the path name prefix. My previous revision failed to define a necessary macro

You will need to get the latest updates and do another build.

That particular problem should now be fixed. Let me know if you find any other issues.

On investigation, I found two issues that were probably contributing to the problem with loading tape files: As I rather thought, the Pico code was writing diagnostics to the serial port. I have now hopefully removed all such diagnostics from the default build. The "memu.cfg" file contains...

SDHC cards are supported. On my VGA demo board I have installed the headers and cut the tracks joining GPIO20 to SD_DAT1 and GPIO21 to SD_DAT2. Cutting these tracks makes GPIO20 & GPIO21 available for serial I/O. See section 3.3.1 of https://datasheets.raspberrypi.com/rp2040/hardware-design-with...

The problem was caused by a new release of the Pico SDK. Earlier SDK releases have included incompatible changes to the TinyUSB API needed to drive the keyboard. My code therefore includes a check on the SDK version number. The v1.4 SDK release does not appear to have introduced any changes in the U...

Dave, for your non-WiFi devices, can’t you get a WiFi to wired bridge? Mark Hi Mark, I have looked, but couldn't see anything that would do the job, or rather, something that I knew would work with the EE dongle. I'll look again though, as, as good as it is, the dongle not supporting wired connecti...

The cancellation of the train strike came too late for me to attend. I hope that all those who make it have an enjoyable and productive day. Something RaspberryPi based me thinks! Hope you can make it. Can't be, Martin. When was the last time you saw a Pi for 30 quid? :lol: The one Raspberry Pi that...

Marin's approach may be better if you have a very large .COM file. CPMVDP works by copying itself into high memory, then loading the new COM file beneath it, before jumping to the start of the new program. So it takes up a bit of the TPA while loading. Once the new program has started it can overwri...

Assuming no train strikes, I am planning to come along.

I don't have anything in need of repair, but I will bring along my £30 Memotech
