I buy a PSP in Canada but it cant play the Japanese game. What should i do

you cant make the xbox multiregion. The only way to play other region discs is to flash the firmware of the dvd drive and then the xbox gets instantly banned, plus you will only be allowed to play that regions games. So if you flashed a european xbox with say japanese then you could only play japanese games not european. If you jtagged the xbox then you can play any region no problems, but again it would get banned , only older xboxes can be jtagged and they are hard to find and not cheap to buy

Best bet is to buy an original xbox for whatever region to play the games

thats because you didnt buy it, you need to buy the game urself to play it on your psp as the game has a security feature that doesnt anyone but the person who bought in their psp play it. if you have firmware 5.03 or below then you can in install checkhen and you can install gen firmwares afterward, gl hf

this is a problem, only japanese games will work in a japanese console. Or, you can get custom firmware for psp(google it) and you can play games from any region, be it europe, japan north america etc.

because you upgrade the system of your psp to a sony official firmware that why you cannot play your games to your memory card you need mod your psp using magic memorystick, pandora battery and custom firmware so that can install custom firmware to psp.

u need a pandora battery ither buy or make one (search youtube)

YOU DO NOT NEED TO CHANGE YOUR REGION CODE 
PSP'S ARE REGION FREE
I BROUGHT SOME GAMES FROM CANAda and i livE IN THE UK
THEY WORK PERFECT

It might be because you have a Japanese texted game, If your running the 1.5 firware homebrew addon then you cant use asian text. What do you mean by normal text?

u can give the psp to sony company

The pal ps2 games and dvds will not play on a Japanese ps3 due to region coding. You can play all ps3 games and blu ray films because they do not use region coding. Some games will also play differently on a ps3, for example, Uncharted: Drakes Fortune (I highly recommend the game) will not have any blood on a Japanese ps3. The region coding feature can not be changed/modified. I would recommend returning Japanese ps3 and purchasing a European model instead if that is possible. Bon chance.
