So I have a launcher-type game. I want to load local, on-disk carts. It works fine in the editor, but as soon as I export it, it fails to work.

The basic code for loading looks like this:
load(cartid, 'back to launcher')

I have also tried putting a './' at the beginning and a '.p8' at the end to no avail.

I put the .p8 files into the same directory as the exe, like:
windows
-- game.exe
-- data.pod
-- sdl2.dll
-- jelpi.p8

How might I go about making an exported game that can load carts from disk?

Found out how to do it, see update 0.1.10
