Sadly this seems to no longer work in the latest version of pico-8 (0.2.2). It crashes when starting a race.
on what platform? Tested when 0.2.2 came out and got no crash on Windows.
Win10, running on a Win GPD 1:
I also tested on my normal PC (also Win10) and it works fine.
Ok so crash is limited to your Win GPD 1 - is the carts folder correctly set?
Load title cart, type: ls - it should list all other virtua racing carts. If not, it means your pico8 config.txt is not pointing at the right location.
Thanks, setting root_path in config.txt fixed the issue.
