Game Pauses On Its Own

[Kajune]

I don't know if this is the right place to post such info, but I need help.

---

I use JPCSP-2733, and I play mainly one game, called 'Katekyo Hitman Reborn Battle Arena 2'.

I previously tried to play it with an older version, and it didn't go past the loading screen. With this newer one, I can at least access the menus and choose characters to fight, but after doing so, it instantly pauses and doesn't respond.

I've gone into 'logger' menu or something, and I can't seem to find the cause there. I don't see any mention of an error, but the game repeatedly continues to pause.

Help?
