yes there is an -accept_future parameter to avoid the version warning: https://www.lexaloffle.com/dl/docs/pico-8_manual.html#Commandline_parameters
if you try it and the cart doesn’t use any newer feature, then you can edit the version inside the cart (P8 are just text files!) so let it load without the parameter by version 0.2.5c
zep released 0.2.5f today so if you can update and it runs the whole problem goes away!
