CPR file doesn't work in C4CPC

[renaudguerin]

When I launch the CPR directly from one of the C4CPC slots, I get a "no cartridge" error.
When I launch it from CprSelect, it crashes after drawing a few yellow lines (see below)
The same file works fine in an emulator (RetroVM), and other CPRs work fine on my C4CPC.
Tested on both a 464 plus and 6128 plus.
