I'm having trouble running specific PS1 games, in particular Zanac X Zanac and Tetris Cardcaptor Sakura. These games have a modchip protection, which I think is interfering with the emulation. Zanac X Zanac stops loading when I select Neo mode, and Tetris Cardcaptor Sakura does not load past the initial blue text screen (http://i.imgur.com/9llZdBN.png). I've found some codes online that apparently solve this issue, but I have no idea where to input them (https://www.reddit.com/r/PSP/comment...e_tetris_with/). I currently trying to load them on my RetroPie, using the lr-pcsx-rearmed emulator.

Anyone has an idea of something I could try?
