Still very early days for the Pi4
the 4mb version is Preorder ony in Australia so not quite available and officially not available until the end of august
according to Pi Australia
Quote: "Does AppGameKit support the new pi4?"
I see no reason why It shouldnt work with later versions of Pi/Linux as to using the new features such as dual monitor
support, I believe you will have to wait for an upgrade. AppGameKit for raspberry Pi is a free product and makes no profit for
TGC so you may have to be patient for upgrades as there resources are being used with AppGameKit studio and other TGC
products which return an income.
PS Ide also like to see further development here for the Pi, but I understand the reasons why development costs
can make these things take time. Maybe they will open source the product in the future who knows
