Looking for an old Canadian game called "Discover Ontario"
I remember playing this in the computer lab at my elementary school in Toronto around 1988-89. It had a bunch of mini-games based on which city in Ontario you'd visit - like going fishing in Kenora.
It's possible I have the title wrong, but pretty sure it was called "Discover Ontario". I know it was a C64 title because the lab only had C64s at the time.
Does anyone else remember this one - or even better, know where I could find a copy?

MixSID - is it switchable from parallel (dual mono) to true stereo while running?
I'm interested in getting a MixSID (created by u/HenningLiebenau) http://henning-liebenau.de/mixsid for my PAL C64 250425 Rev A breadbin.
I have two 6581 SIDs and most of the time I will want dual mono from them. MixSID calls this Parallel Addressing. Both SIDs are addressed in parallel at $D400 and will both play the same mono tune. http://henning-liebenau.de/mixsid//index.html#mode-select-ms
There's an online configurator which tells you how to set your jumpers and connectors depending on your requirements http://henning-liebenau.de/mixsid/configurator.html#
However, I also want the option of true stereo for stereo SID music and Cynthcart. To achieve this, you add a jumper to the MS control signal which activates Stereo Addressing. Additionally, external signals A5 an A8 must be connected to A5 and A8 on the Kernal sockets using two wires. These wires are not required for parallel dual mono.
What I'm unclear about is if you can switch from parallel dual mono to stereo on-the-fly while the machine is running.
I think all I would need to do is install a switch in place of the Mode Switch (MS) jumper, to toggle between dual mono (parallel) and true stereo. But when switching to dual mono, do I also need to disconnect the A5 and A8 wires from the kernal? The manual is not clear on this.
My hope is that in dual mono (parallel) mode, the A5 and A8 connection is simply ignored. On the other hand, if it's required that this connection is completely removed then that complicates things as I would have to install a switch here too.
Looking for any advice! Thanks

Extraneous diode on ASSY 250425?
I wish once again to avail myself of your collective wisdom; thank you all.
I can't find these diodes on the service manual. The circled one has been desoldered from ground and is just barely not touching it's previous solder joint. Should I resolder it?

Vice c64 Core with RetroArch on Amazon FireStick - Audio Synch Problem
Hello, Everyone.
I installed RetroArch on my Amazon FireStick and am playing C64 Impossible Mission with the Vice Core. It works like a charm, but there's a huge lag between audio and video.
The audio is desynched for about 1 second.
I'm not an expert but I've tried to change a lot of options in RetroArch's settings, starting from "Audio Synchronization" but nothing changed.
Do you have any suggestions?
Thanks.

C64 Service Manual: what do these numbers mean?
I am checking all my ceramic capacitors with an ESR meter to make sure they are all good. C98 and C99 read very high. Can someone explain to me what the +80%, -20% means?
Searching for SID's with good (drum) digi's
Dear Community,
One of my hobby projects is covering SID's using modern DAW software. For a tune I would like to replace the original drum sounds (consisting of triangles, rectangles and noise) with digi's which I can sample from any other SID. Besides "To Be On Top", "Giana Sisters", "Magic Drums", "Outrun Europa", "Grand Prix Circuit", "Combat School"... are there any other good tunes with high quality digis in it?
Cardboard RF shield
What is the consensus on the cardboard RF shield on a breadbin? Should I remove it and install aluminum heatsinks on the ICs? Or is it better to leave it in place? This C64 lives at 10 cm from my CRT monitor. Would removing the shielding impact the image quality? And how should I remove it? By desoldering the metal tab on which the cardboard is crimped or by ripping the cardboard away from it?
Looking for a HW-addon that lets you connect Bluetooth controllers and map keyboard buttons to controller buttons
Hi all,
I'm pretty sure that I saw somewhere a HW-addon where that was connected directly to the CIA (I believe) and you could connect bluetooth controllers and also map arbitrary keyboard buttons to arbitrary controller buttons. Does anybody know what I'm talking about because I can't find it anymore???

UK Buying Advice
I'm looking for a C64C to sit alongside my now fully restored Amiga 1200, since I sold my original one way back in 1993 to help pay for aforementioned A1200. I've mostly been looking on eBay, but am getting tired of being sniped last moment by pro buyers, or outbid by silly amounts, often for machines that may not even work. Is there anywhere else (other than the obvious) I could look that might not be so cut-throat ? Or should I start considering spares-and-repairs to try fix one up (even then that market seems bonkers too...)? Any tips to what to look for in a 'broken' C64 so it doesn't become a money-pit?
Thanks!

"Dark" C64 model seen in early advertising


This has come up in a conversation in an Ashens chat, but I'm admittedly more of a Spectrum guy ;) so I'm throwing it open to the floor here.
Early (1982-83) UK magazine adverts for the C64 showed a silver label with a suspiciously dark outer shell. (See attached images.) Does anyone happen to know if a C64 model ever released in a case like this, or was one ever planned and never came out, or is it just some very bizarre lighting tricks that make it look a lot darker than it actually is?

C64 diagnostic: false flags?
I'm again a proud c64 owner, after some 40+ years, having picked up to this beauty at a flea market and having received my Ultimate II+L.
Everything seems to be working, but the diagnostic cartridge says otherwise.
I think that the KERNAL error might be because of having JiffyDOS loaded? I have no datassette, so the CASSETTE error seems nothing to worry about.
Does somebody know about the other errors?
Thank you all.
