Hey is this still getting a physical GBA cart release? Thought I saw it on this page a while ago, but don't now. Are you already sold out for pre orders?
Just found this site for preordering the cartridge:
https://firstpressgames.com/products/goodboy-galaxy-gba-na-regular-edition
As the devs, can you tell me if the site is reputable?

The weird part: You can buy counterfeits on aliexpress. However, you never know what version they are burning and the cards may fail spontaneously because they usually lack quality control. But if you don't have an Everdrive or an Analogue Pocket or some emulation device, then this might be the only way to play the game on a good handheld.
