Great video, now I will have to stop in and order a North of the Border Destest Max 2 when it's available. Matt has done something no one else has in 40 years.
The regular C64 diagnostics adds a lot more tests than just audio if you connect a test harness. This is not going to replace the regular diagnostics just yet. Still a good RAM test though.
I actually had a similar issue with the same chips from AliExpress. They were rebranded something-or-other (can't remember now), I got a full refund and ended up using them for another project
What am I seeing? Is the DesTestSwitch firmware actually switching between MAX mode and C64 mode automatically, or are you using the features of that MaxSwitch cartridge to do so manually? I'd like to know if this version of DesTest can take advantage of the existing VersaCarts out there, that a user can manually switch between a C64 cart and a MAX cart. I already adapted a VersaCart to run the original DesTestMax and would like to re-use that if possible.
The special hardware in the DesTestSwitch cartridge allows switching between /GAME (MAX) mode and /EXROM mode under software control instead of with a physical switch. It is still possible to put each "half" of the DesTestSwitch solution on separate carts (or a switchable-cart) - except for the full 64K test "half" the machine must be alive enough to run the kernal. The Switch solution can test all 64K and doesn't require the ROMs, CIAs or SID.

Have a happy new year More Fun Making It

Amazing! Can’t wait to see the final product!!!
This is an awesome project. Matthew is a very intelligent guy. Thanks for sharing
Oh I'd love one or two of the perfboards. I've an idea or two bout developing my own diagnostic 'cartridge' (ROM and hardware based with a Pi Pico)
I hope the border patterns don’t go away, it’s a good way to know that the computer is still doing a thing and not just hung.

I will take them off of your hands , if you have not given them away already !
