A while back I found this patch for CTTR that adds the PSP content to PS2 save files on PCSX2. I found out recently that PCSX2 runs are now accepted and I know a lot of PS2 runners use Crash's PSP car since it's most optimal, so I'd thought I'd share this and was hoping maybe it could be accepted in runs. I've been using it for months now without issues and it works really well. It automatically adds all the PSP content to any save file you have load. You can even load a different save or create a new save without having to close the game. You can also patch the iso file directly and use it on an actual PS2 and/or PS3. Here is where I found the patch: https://www.reddit.com/r/crashbandicoot/comments/1c3agno/crash_tag_team_racing_psp_exclusive_content/
