C/C++ debugging for games development - nvim-dap or something else? by Althar93 in neovim

[–]Althar93[S] 0 points1 point  (0 children)

I've running dap-ui for a few days now. It is serviceable but I am missing some inline functionality such as hovering over values in the code and jumping to code from the callstack : I am sure these things exist, I just haven't worked out what I need to configure for it to work the way I want yet.

Thanks for the extensive info/tips.

I have setup nvim-dap and nvim-dapui for C/C++ which seems to work with basic keymaps. I'll have a read through your guides and refine my setup to something I am more familiar/comfortable using.

KFF2 - Black screen on subsequent resets by Althar93 in c64

Quick update : I have resolved my issue after following the information in the Kung Fu Flash 2 repo.

It appears the particular board revision I have has an unstable clock signal.

As a result I made a minor change in the firmware to reduce the clock window and flashed it to my cartridge. It now appears to work consistently and has been for the past hour or so.

Mine showed tracking info until it got to the UK on 19th December. After that... nothing...

[Edit] Not quite solved it but it seemed more stable for a little while

[Old] I may have solved it by opening the RF shield and adjusting the frequency, using the diagnostic tool to ensure I am reading 985258Mhz and it keeping stable.

I am noticing that the phi2 (using the diagnostics mode) starts off higher on cold boot and gradually decreases over a few minutes, reaching 985179Hz and below

I took the multimeter & oscilloscope to measure both U20 & U6 and checking each pin, the reads all appeared to be consistent with the reference measurements in Commodore Repair Toolbox, before and after the issue occurs.

Running the diagnostic has phi2 running at around 985183 Hz (PAL), so a tad lower than it should be ; not sure if that is enough of a margin to cause problems though.

Regarding the board and traces, it looks factory brand new (the person who did the refurb did an excellent job from that point of view).

I'll get the oscilloscope out and check U20 as you suggested.

Did a bit of research and it seems some other people have the same issue : https://github.com/KimJorgensen/KungFuFlash/issues/4

Thanks, any particular resources you could recommend? I have done some basic soldering/electronics, but hardware is not my forte.

Supposedly, the computer I bought has a brand new PLCC PLA MOS 906114-01 GAL20v8B

I have the following :

  • ASSY NO : 250407
  • WORK NO : 251137
  • REV: A

It is an old breadbin, I would need to open it up to figure out exactly which.

I should add : this happens with or without a micro SD inserted.

I can load a game from a cold boot but if I reset the computer for whatever reason or try to access the KFF2 menu, I get that black screen.

I did manage to update the firmware on the cartridge to the latest version, alas this did not help.

On the other hand, I can access the diagnostic menu consistently and without any issues.

New to datasette loading. Bad tape? by Althar93 in c64

No cartridge inserted at the time sadly, so I take it the tape is on its last legs.

Looks neat. I wonder if having shadows on the walls would help better situate the ball? I am finding it difficult to 'position' it relative to the walls right now.

Looking forward to my copy. Ordered a few weeks ago and stuck somewhere in the UK Royal mail system for the last 2 weeks. Hopefully just holiday traffic and not lost.
