fixes saveicons in Hentai Ouji To Warawanai Neko and in Toradora! Portable.

The following pics are the source of addresses of Kirameki School Life, Hentai Ouji To Warawanai Neko and Toradora! Portable,they pass the address to A2 and then call function,so replace at the start of the function it calls ,so that don't need to make each a hook.
