I was searching for a pico8 cartridge 3d model for my game cover picture. But can't find one. Therefore I model it myself. The texture in original file in this model is in .p8.png so maybe it's playable. (too lazy to try)
I know pico8 is more like NES level console. but their exported png cartridge looks more like SD card or cartridge for NDS~Nintendo Switch.
Feel free to download the model if it helps for your project. Also feel free to try my game.
