What about the VRAM constraints caused by increased memory footprint (doubled back buffer size)?

I didn't think about that to be honest... I figured they did it on some games so it should work with all... lol

I think this is achieved by decreasing to 16bit color rendering. Here is one example:

20132F7C 34421400 //read 16bit, 12000090 to 00011400
20132F8C 00000000 //clean 120000A0
201336E0 24050100 //no squash

Wow, this patch is hideous. I have not looked into the code deeply, it does change the buffer address for the VU1 microprogram to send, but I do not understand why the colour depth is lowered. The videos do not work at all (because of the forced progressive mode), and the patch does manipulate the front buffer after all.

Well, the game has got a sharp and clean back buffer ready to enable. Here is the proper patch:

"The code works similar to other 448 height codes in the way that it will display 640x448 in 16bit, so it can fit in the same amount of vram"

These codes are made for PS2 hardware. I haven't tried the code in your link but the code I posted works fine with some limitations (FMVs,16bit etc)

I wish had the time and experience to find 480p codes. RR5 in 480p is still a dream...

I understand why it is switched to the 16 bit, I do not understand how. But I am not interested in this game to inspect it further. This code just looks inferior to me than the one I linked to. The overall image quality is lower and the game is broken (videos are not working). I like when the image quality is increased, not decreased after all.
