What a coincidence, I just spent to wee hours this morning trying to find region free hack for the panasonic dvd-f87 5 disc player, didn't come up with a thing. Wake up to your post, tried it worked. Thank you. But it didn't work on my Panasonic Bluray player, which is a DMP-BD60, which doesn't look good for your bdt-220 bluray player.

Now I will try to help you. First code 0490, is the setup code to control your bluray, does it? Does power , play control the BR? If not, you will have go into the menu of the panasonic and adjust it to REMOTE 1 code, and the oem remote as well. I'll go on, The 5 digit codes have to be mapped to keys on your OFA remote, one at a time like so:

1. hold magic button until the DVD button lights up and stays lit
2. press 994 (DVD button blinks twice)
3. press magic
4. enter 0 0 1 9 1
5. press #1 key, the light blinks twice.

Now the next one:

1. hold magic button until the DVD button lights up and stays lit
2. press 994 (DVD button blinks twice)
3. press magic
4. enter 0 0 1 2 0
5. press #2 key, light blinks twice

next:

1. hold magic button until the DVD button lights up and stays lit
2. press 994 (DVD button blinks twice)
3. press magic
4. enter 0 0 0 6 5
5. press #3 key, light blinks twice

now repeat for the other seven 5 digit codes, except changing the 5 digit code in step four, and the button number in step five.

Once all digits are mapped, then try the steps, pressing 1 through 0, one after the other.
