![]() So that's why I say it might be an undertaking. However, this would definitely mean non-trivial changes to the game's code. There may be a performance penalty, but it might be livable. That being said, it's theoretically possible to relocate textures and CLUTs to regular RAM. So it may have become a decision of more vibrant colors or better shadows, for example. You basically double your remaining VRAM by using 16-bit colors, allowing you to do a lot more other effects. So many games may have chosen 32-bit color simply due to free space, not even because of bandwidth. * Other buffers (to create bloom effects, or shadows, etc.) So you can see that with 32-bit color, you're quickly left with only 2048MB (VRAM) - 272KB (depth) - 1088KB (colors) = 688KB of remaining VRAM.īut you say, "it fits, doesn't it? Is that a problem?" But this VRAM has to be used for other things: So it's actually 555KB vs 1088KB.Įven more, most games will require a depth buffer to render properly at all. Additionally, you essentially must double buffer on the PSP, meaning you need two of those buffers. The PSP had 2MB of VRAM, or in other words 2048KB.Ī 16-bit color buffer requires 272KB. ![]() Well, forcing games to run at 32-bit color on a real PSP may be a feat, unfortunately. I have Kingdom Hearts and this is what I will try now. If you read the link from PPSSPP devs, you can see that Kingdom hearts has an option to choose 16 or 32 bit color and this could be a way to understand what function does this, and port it to other games. So, what we REALLY need to do is force the games to run with 32 bit color on a REAL PSP, identifying the code that set this. It is same trick as used in PS1 games thats why you can see it on those games."Īnother user says: "Blame it on the PSP's limited memory bandwidth, which forced a lot of games to run in 16-bit color or less."Īlso, READ HERE about 16/32 bit color from PPSSPP devs. (01-05-2016 12:51 AM)Kabuto_Kun Wrote: "Technical" info:Īccording to some user from a different forum, the dither effect on PSP "It is done to save VRAM so that more textures can be loaded and helps to keep higher fram rate.
